Winter, cold, lonely houses and... a big nice snowdrift in the place where you left your car yesterday. Say it doesn't happen! How it happens! Winter is an unpredictable time. It may not even reach a car immured in a snowdrift, but all the same, a car that has stood for several hours in severe frost is unlikely to start.
So, an emergency situation: it's cold outside - your car is half dead. Or is it still half dead? Be an optimist - hope for fortune.
Great luck if you removed the battery in the evening and kept it warm at home, but if this capricious part of the car did not warm up at home, then it’s better not to try to start the car right away - take care of the charge!
Also consider it lucky if the car stopped in a crowded place, that is, where there are still cars and sympathetic drivers. They will help with advice, try to start the car with a pusher (this is if the gearbox is mechanical) or, out of the kindness of their hearts, they will give you a "light" from their working battery.
But if luck turned away, no one offers help, then rely only on yourself.
We suggest you use five effective ways from experienced motorists how to solve the problem of starting a car in hard frost.
Tip one, the most primitive - "grandfather's" way
It consists in warming up a frozen battery by any means at hand. You can take it off, take it home, lean it against a radiator, or even immerse it in a hot bath. It is impossible to completely fill the battery with hot water - it will deteriorate. But, if you are a fragile girl or an intelligent young man in a festive suit, wearing a battery is not the right thing to do. In this case, if the mountain does not go to Mohammed ... That's right, we ourselves carry heat to the battery. We collect two two-liter plastic bottles of very hot water, grab a warm blanket and carry all this wealth to the car. We put the bottles on the sides of the collector and carefully wrap it with a blanket, touchingly tucking it in on the sides. You should not sing a lullaby, you just need to wait a little - ten to twenty minutes. To calm your nerves, you can drink a plastic cup of coffee in the cold - it greatly adds optimism and confidence that you are a brilliant follower of the national inventor Kulibin.
After such simple manipulations, you need to turn on the high beam for a few minutes to start the process in the battery, and then you can start the engine.
The beauty of this method is that it is simple, understandable, affordable and, most importantly, free!
Tip two, low-budget - use synthetic oil
If in the summer you buy an ordinary mineral oil, then in winter you should change your preferences and buy synthetic or semi-synthetic oil. The fact is that synthetic types of motor oils have a pumping temperature much lower, due to which the engine starts normally even in cold weather. But this advice is relevant only if the reason for the failure to start the engine is thickened oil in the crankcase. Actually, in winter engine oil worth checking when buying. Leave the canister in the cold, and then look - good winter oil splashes, and unsuitable - thickens, a hard film forms on top of it. Perfect advice - buy engine oil (as well as diesel and gasoline) from famous brands and in approved locations.
Tip three, exclusive - for those who have a car in a paid or guarded parking lot
Set a timer on the starter that can periodically start the engine for a few minutes so that it does not cool down so much. The optimal period between such offline launches is every three hours. Warming up the car in this way is a good way out, but only if the parking lot is closed and guarded.
Tip four - for those who are at least a little minder: clean the candles
The performance of glow plugs should be checked at least occasionally. Due to old and bad spark plugs, the car may refuse to start in the cold. Candles may be new, but if you immediately pressed the gas terribly hard with a frozen engine, they can simply fill with gasoline. The way out is to change the spark plugs. But it's a long time, and you need to go now. If there is no time to change the candles, then you can simply clean them from soot or from gasoline. It is necessary to unscrew the candles (not too long a procedure, but requiring at least some kind of "green" concept in the motor) and clean them, for example, with a toothbrush. To heighten the effect, use modern cleaning powders or gels. Do not get carried away too much - you can damage the insulating layer. Then it is desirable to dry the candles or just heat them up. The hotter the better. Replace clean and dry spark plugs and start the car.
Tip five, not cheap, but the most optimal: buy a start-up Charger
All folk remedies are good, but special technical devices are always better and more reliable. It's like treating a cold: we drink herbal tea for a while, gnaw on lemons and swallow honey, and if it doesn't help, we buy medicines in a pharmacy.
Such a “pharmacy” preparation for a frozen car is an autonomous starting device. This is a compact and convenient device, popularly referred to as a "booster" - a real lifesaver for a motorist in the event of a battery failure. The starting device acts as a current source for the starter, the charger charges battery, and the launcher-charger (ROM) device does both.
Autonomous PU is also safe for supernova cars with digital control system, because it will simply supply starting current to the circuit to start the engine. Practical and small starters with good protection will help out anytime and anywhere - in the field, in the forest, in the city. You only need to connect the terminals and press the button.
Every driver knows that starting the engine of his favorite car in severe frost has a detrimental effect on its further operation. The battery loses its power up to 50% already at -20 degrees C, all chemical processes in the engine slow down, frost binds the engine oil. To facilitate the safe starting of the engine, the industry offers various devices, chemicals: "starting" liquids (the most common are "Arktika", "START-UP"), start-charging devices, remote start systems (the engine starts automatically at a given air temperature) and much more. Not every average driver after buying a car has the funds to purchase additional devices.
There is a need to find other ways to "revive" a frozen car. To start the engine in severe frost, there are no universal tips. There are drivers' skills that have been developed during operation, which are successfully used in the winter season. However, starting the engine first of all begins with the application of some general rules.
The main condition when starting a car engine in severe frost is that the battery should not be old and weak. To give strength to the battery, you need to warm up the electrolyte by turning on the high beam of the car for 15-20 seconds or for 5 minutes of “dimensions”. Before turning the ignition key, it is necessary to fully depress the clutch pedal (on the "mechanics"). This greatly facilitates the cranking of the engine by the starter. Attempt to start - no more than 4 seconds. If necessary, this action can be repeated several times with a period of one to two minutes. You don’t need to get carried away - 3-4 times is enough, otherwise gasoline will flood the candles. It is possible, after depressing the clutch, to turn on the ignition, while not starting the engine. Wait a couple of seconds, allowing the fuel pump to come into operation, and start the engine. The clutch is released only after the engine warms up, smoothly, without jerking, while the gearbox must be transferred to the neutral position.
Drivers also successfully use this method of starting a carburetor engine - “pour into the eyes”. Its essence is that a small amount of ether is poured into the fuel wells of the carburetor. It is important to close the lid tightly, since it is not the ether that ignites, but its vapors.
When starting the engine, you can also use the so-called “explosive mixture”, adding a small amount of gasoline already in the tank (5-6 liters per full tank) with an order of magnitude higher octane rating. If you use this mixture only in emergency cases, then it will not cause harm to the engine.
With an injection engine, cylinder purge is successfully used. To do this, the gas pedal is pressed to failure and an attempt is made to scroll the engine using the starter.
The way to “revive” the car perfectly helps - “light it up”. This requires a second car. Two batteries are connected by wires in order from weak to strong (donor). "Engine donor", while it must be muffled. After connection, the “donor engine” starts and keeps in working condition. After a while, it is muffled, and an attempt is made to start the required engine. In this case, you need to remember that a weak battery, when receiving a large amount of current, may explode. To ensure your safety, it is better to move away from a weak battery.
Drivers should remember that when starting a car engine in severe frost, it is necessary to turn off all additional energy-consuming equipment: car oven, radio, radio, headlights, lights, heating.
If, after the resuscitation measures taken, the car still does not start, the search for other methods acceptable to this situation begins.
One of the recommended ways to start a car is to warm up the engine with a heating source - a household heater. To do this, insulated material is thrown over the motor part of the car to the very bottom. The heater is placed under the engine, but it must be with a closed coil and under constant control. The method is dangerous. Instead of a heater, it is better to use a fan heater, it will be safer. It, like a household heater, is installed under the engine.
The greatest effect is achieved if the intake manifold is heated by pouring water on top of it. You need to start with warm water (so as not to burst from a sharp temperature drop), gradually increasing the temperature to hot.
When warming up the carburetor engine, it will be good to squeeze the gas pedal several times (2-3). In the intake manifold, the pump will supply a small amount of gasoline. As a result of heating, it will evaporate and form an easily ignited mixture.
IMPORTANT! Do not use a blowtorch to start a car engine in severe frost when heated. DANGEROUS!
It is guaranteed to start the car engine in severe frost in the simplest ways:
- put the car in a warm box;
- take off and put in warm room battery;
- go out periodically (after 2-2.5 hours) to your car and start the engine to warm up.
Reliable and safe.
Good luck on the roads!
Probably every motorist faced the problem of starting the power unit in extreme cold, when you need to drive, and the car let you down and you had to get on foot in the cold. But maybe the fact is that you made a mistake during its launch?
For an easy start, the safety of some elements in good condition is important, but it's not just about them. We will tell you the correct actions and their order when starting in cold weather, as well as their differences in gasoline and diesel cars.
A few rules for starting a car in cold weather
A few tips on how to start the car in cold weather and not drain the battery, since cold start has several specific features:
- In severe frosts, before starting the engine, you need to warm up the battery. This can be done by turning on the high beam for 10 seconds. After that, turn off and wait a minute, run the start.
- If the engine does not start on the first try, you can try to put an additional load on the battery and turn on a few more current consumers, for example, heating or music.
- After ignition, wait a few seconds, at this time the fuel pump will pump gasoline, then start the car engine.
- It must be remembered that when starting up, all electronic devices of the machine must be switched off. This will help minimize battery consumption.
These tips will help not only to properly perform a cold start of the engine, but also to keep the battery in working condition.
Why is a good battery so important in cold weather?
The answer to the question “how to start a car in cold weather” is quite simple - a good and serviceable battery is the key to a successful launch.
A good battery is essential in sub-zero temperatures, as very cold weather puts a lot of strain on the battery. Namely, if you do not delve into the ongoing electrochemical processes inside the battery, then the reason for the decrease in the level of charge and the increase in the discharge characteristics of the battery is an increase in the viscosity and resistance of the electrolyte.
In a very negative temperature in winter, the resistance to scrolling the engine shaft increases significantly and, in turn, the starter current consumption from the battery increases. In conditions of extremely low temperatures without the use additional funds, facilitating the engine start, the battery gives off a charge faster than it restores. Therefore, with a systematic consumption of energy in the cold season, the battery cannot accumulate it to the required extent, which ultimately leads to its complete discharge.
Thus, in an unambiguous way to assess the condition of the battery will help the level of its charge.
The battery voltage rate is 12.6 - 12.9 (V) in a charged state, if the value is less, your battery is discharged.
Starting the engine with a dead battery
How to start a car in cold weather if the battery is completely discharged? The car can be started using an external power source. It can be a starting device or a battery of another car connected to a discharged battery with a cable.
Important! If the battery is frozen, then it is strictly forbidden to connect an external power source. This may cause an explosion.
Using the starting device, you can start the car without connecting the battery to a power source. Such recharging can guarantee 15-30 starts, which in the future directly depends on the air temperature and battery performance.
Starting Devices
The starting device is often used when replacing the battery in order to prevent the disconnection of current consumers and, as a result, the loss of saved data and settings.
If there is no charger at hand, but there is another battery, then you can use it to recharge the discharged one. This is of course long, but will allow you to start the engine.
There are a few things you need to know when charging a battery with another:
- It is important to remember to connect the terminals correctly as polarity mismatch can result in electric shock.
- A discharged battery must be correctly installed and connected to the vehicle's on-board network.
- The battery voltage must be the same.
- The nominal capacity indicators must correspond in such a way that the capacity of the battery from which there is a charge must be less than the capacity of the discharged battery.
- Before shutdown start cable it is worth turning on some electronic devices, with the possibility of eliminating current surges.
What else can help a frozen car?
Keeping in mind a couple of organizational points, you can be sure that the car will start in cold weather.
- You need to warm up the engine! Experienced auto mechanics recommend periodically warming up the car engine in frosty weather. And after starting, the temperature of the coolant should reach 40-50 degrees. If the temperature on the car is not displayed in numbers, then you can see the warm-up in terms of speed, they should drop to 1000 rpm. After that, it is possible to start a smooth movement of the car without sudden accelerations and braking.
- Bad oil. Due to the old and, as a result, contaminated oil, most often its primary characteristics no longer correspond to the operating mode, therefore, due to frost, such oil often “does not start” the moving parts of the car. Therefore, timely oil prevention will help to forget about this problem, especially since it is almost impossible to quickly change frozen oil, you will have to warm the car in a warm room.
- The spark plugs are full. If you have been turning the starter for a long time while pressing the gas, you may have flooded the candles, you must immediately stop trying to start the engine and wait a while. When gasoline drains, you can try again by fully depressing the gas pedal and then turning the engine with a starter, the car should start.
- If the car is equipped with a start-stop button, you must first press it to turn on the fuel pump and pump pressure into the system. You will hear the pump turn on. Then we already squeeze out the brake and press the button again.
The special science of the diesel engine
Due to the peculiarities of work and the principles of the structure, they have their own operating conditions during the period of low temperatures in winter. In practice, given these principles of operation, you can count on the successful launch of a diesel engine in cold weather.
All the nuances of this type of engine lie inside it, in its design features devices.
First, this diesel fuel. At a temperature of about 0 degrees, the paraffins that make up the fuel become gel-like, which becomes an obstacle to its penetration into the engine itself.
Secondly, the method of ignition itself fuel mixture. Diesel fuel, unlike gasoline, where the ignition process occurs from a spark, ignites from high pressure. But at a negative temperature, diesel fuel is not able to warm up and flare up.
For diesel engine winter comes with a temperature of + 5 degrees and as it decreases, all the problematic moments make themselves felt at startup.
To prevent this, it is necessary to change the fuel to winter fuel in time, there are three types of diesel fuel in total:
- summer - freezes at -5 ° C;
- winter - used up to -35 ° C;
- arctic - freezes at -55°C.
Preparing for winter, if you will frequently start a diesel engine in cold weather, should include:
- Compression pressure check. If the compression index is less than 25, and the air temperature is below 20 degrees, then the car should not be left on the street or it is necessary to warm it up.
- Checking candles. Glow plugs must provide in the combustion chamber the temperature necessary for the process of self-ignition and mixture formation. When preparing for winter launches, it is worth checking by connecting them to a power source, within 5 seconds they should glow, otherwise replacement is necessary.
Starting a diesel engine in winter
When starting a diesel engine in low temperatures in winter, first of all, it is necessary to check the condition of the battery and only then proceed with the start. If it so happened that the engine does not start the first time, you need to ignite the glow plugs several times.
This is what a glow plug looks like
The light bulb will serve as a reference dashboard or characteristic sound- click relay. In the beginning, after warming up the glow plugs, you must wait until the relay turns them off. Then turn off the ignition and, after waiting for a while, about 15 seconds, repeat the same action. With this method, if your candles are in good condition and the fuel is flowing properly, the engine should start.
If there are no problems with your engine, then you can use a special flammable aerosol. The use of such mixtures will help to reduce the required temperature threshold for fuel ignition. They also contain additives that lubricate the parts and thereby eliminate dry cold friction at the time of start-up.
Errors when starting a diesel engine
And so, imagine, on a frosty winter morning, you decide to start your car. Even if the car passed winter training in full, it is necessary to adhere to a certain algorithm.
It is important to remember about warming up the battery and candles. First of all, the biggest and most common mistake of car owners in this case is heating up the battery with a high beam, but this technique is effective only on petrol engine. Diesel behaves differently and the best option the ignition will be switched on for a while, up to 15 seconds. This helps the battery and spark plugs to warm up before winding.
Modern diesel cars very often they have in their configuration a system with a start-stop button. They have a special mode designed to warm up the glow plugs. In order to use it, you need to press the button, while not pressing the brake, usually 6 seconds is enough. After that, when the glow plug icon on the instrument panel goes out, your engine will be ready to start.
The diesel must be started with the clutch pedal depressed. At the same time, the starter turns the engine for 15 seconds. If the engine does not start, you can wait a few seconds and try starting again.
Therefore, take precautions and do not try artisanal methods if the car is dear to you and the time you lose if it breaks down, not to mention finances. It is more important to be prepared for frosts in advance and then you will not know what “won’t start” means!
With the onset of winter cold, many car owners face a problem: how to start?. Probably, there is not a single driver who would not ask for a "light" when No one is insured against a sudden stop of the battery. There are many reasons for discharging and breaking batteries. Before deciding on specific actions, it is necessary to familiarize yourself with all of them in more detail.
Reasons for a dead battery
There may be several of them:
- Expiration of battery life;
- Battery failure;
- Untimely recharging of the battery;
- Improper operation, frequent recharging.
How to start it? What to do if the car battery runs down in the middle of the road? These questions concern many. Most batteries lose their charge in cold weather. This is facilitated by a sharp change in temperature conditions. The cold time does not benefit the device. This is especially true for cars that are on the street for a long time. Also of no small importance for operation in the cold season is the load.
If the load is excessive, it is natural that the device will be discharged faster, and this will lead to a decrease in its shelf life. You can get out of this situation.
Extending battery life
Ways to minimize battery failure:
- correct operation vehicle, which provides for proper care for him at sub-zero temperatures. In other words, the car can be left in the cold at low temperatures only if the battery is removed from it;
- do not leave the vehicle unattended for a long time;
- when the battery is discharged, it is necessary to provide an emergency method of charging or have a spare one;
- you can try to “light up” the engine or ask other motorists to do it;
- use special for fast
There are times when it is impossible to count on someone's help and only special device. Therefore, the best way out of this situation is considered to be a one-time cost of funds for the purchase of charging equipment.
Devices for starting the engine with a dead battery can be varied:
- Asian origin;
- European;
- CIS countries.
Sometimes a starting device for a car is called a booster. Unknowing people consider this device to be auxiliary.
But they are deeply mistaken. This is a completely separate equipment with certain quality characteristics:
- its capacity is much less than a conventional battery;
- the internal "stuffing" is also different;
- produces a different voltage.
Connecting a device to start the engine with a dead battery provides for its connection to power unit vehicle. This booster is only suitable for cars, since the power for its use must be about 12 V.
How to use the device?
Tricks to use:
- The process of operating a device for starting an engine with a dead battery involves throwing "crocodiles" on a dead battery, as a result of which an electric current will appear. The rules for using devices are different for each manufacturer. Therefore, before using it, you must carefully read the instructions, and only then take action.
- Starting the device should not harm the battery. A single exposure to the battery should not exceed ten seconds.
- Charging works only from the mains. Therefore, if trouble happens on the road, only a cigarette lighter can help.
- When operating the booster, it is contraindicated to leave the device in the cold for a long time.
Exceptions are professional and semi-professional devices used by car service specialists.
Functional features of the device
If you decide to purchase a charger, the best option would be a device that contains a battery indicator indicator.
In the absence of this functionality, it will be difficult to use the starting device for the car. How to choose it correctly? When buying a device to start the engine with a dead battery, you need to pay attention to the following indicators:
- the device must have built-in zero discharge protection, since such a device will last much longer;
- the possibility of further charging;
- the power of the purchased device must be appropriate.
To avoid trouble, purchase equipment in specialized stores who will be able to provide relevant documentation on the quality and safety of the goods. Only in this way you can protect yourself and your transport.
How is the process carried out using a quick start engine?
First you need to know that when connecting, you must observe the correct polarity.
The next step should be to control a certain voltage flow, which should be 20 A. Depending on the battery, certain errors can be observed, but they should be minimal.
As the battery charges, the following conditions may occur:
- electrolyte viscosity decrease;
- drop in internal resistance;
- an increase in the starter capacity of the battery.
If you turned on the battery starter, while the battery was fully charged, then the voltage at its terminals should quickly reach the required values and it is not recommended to recharge it. In this case, you should pay attention to turning on the starter of the charger-starter. If, after the measures taken, your vehicle still does not start, turn off the ignition and give it the opportunity to rest a bit.
Practice shows that after this rest, the voltage on the battery will begin to increase and after the transition of a certain technical specifications indicator, you can think about recharging. If the experiment has taken a positive turn - disconnect the device from the battery. This action should not be ignored, as parallel operation can help recharge the battery. This will negatively affect the performance of the car.
be careful
After several ineffective attempts to start the engine, it is worth stopping any work in this direction and trying to find a breakdown problem in another. Otherwise, you will simply break the equipment and the starter, they will fail as a result of overload.
The second option for solving this problem would be to contact a car repair shop equipped with modern technology, which in the shortest possible time will be able to diagnose and find the cause.
Actions in case of prolonged stagnation of the battery
If you are faced with the question of starting the battery after a long period of inactivity, you need to have the following knowledge:
- We start the car after a long idle time carefully, carefully.
- What does the previous action mean? This means that a 3 month downtime period will not affect the battery. And in the event of a longer downtime, you will have to carry out a certain set of measures, namely, checking vital components.
After that you need to do right choice charger.
The safest method is to use a quick engine starter. Today it is the latest achievement of technology in the automotive world. This device is capable of passing a fairly large flow of energy through itself. It is this amount of energy that is enough to fully charge the engine.
Terms of Use
When working with such equipment, remember the following. If you start the car after a long period of inactivity, you will have to remove the battery from the vehicle and carry out a full charge. It is important not to overcharge the battery. Otherwise, it will boil, which will not have the best effect on its functionality. In time, high-quality batteries are charged from 1 to 2 hours. The maximum voltage is 12.5-13 V. At a lower value, the car simply will not start, at a higher value it will harm the battery.

Winter is a severe test for Russian motorists. One of the biggest difficulties is how to start a car in the cold that has stood all night on open parking or near the entrance. Problems begin already at -20 ° C, and in a severe cold, difficulties grow to the scale of a catastrophe.
In the article, we will consider how to start a car in cold weather or mechanics, carburetor or injector, diesel or gasoline. It is unrealistic to cover all the reasons and solutions, since there are thousands of options, but we will consider the main ones in detail. If preheaters are installed in the car, there are no difficulties even at -30 ° C, but these devices are expensive.
How to start a carburetor engine in cold weather
Let's start with cars with a carburetor engine. For example: how to start a VAZ in the cold, or UAZ? The main reasons that prevent you from quickly starting a gasoline engine in winter:
- thickened oil;
Look into exhaust pipe- Condensation can freeze in it. Sometimes it is enough to clean this part to make the car come to life. If the exhaust is free, we act according to the algorithm.
1. Battery preparation
When we start the car in severe frost First of all, you need to revive the battery. At sub-zero temperatures, the battery loses 20 to 50% of its power. The fact is that the electrolyte in the jars has cooled down, and the chemical reactions in it proceed slowly. On a weak battery, the starter will not be able to develop enough power to turn the engine shaft.
The first paragraph of the instruction on how to properly start the car in cold weather: you need to cheer up the battery by turning on the high beam for 5 seconds. The electrolyte in the jars will warm up and the battery will be ready for hard work. After 10 seconds, we proceed directly to starting the engine.
2. Checkpoint cut-off
The next step is to pull out the gas suction. Not necessarily all the way, enough for 15-20 mm. Now we start the engine, but first we squeeze out the clutch pedal. So we will facilitate the work of the starter - he will not need to turn the shafts and gears of the gearbox with oil thickened in the cold. This mistake is sometimes made by beginners who do not know how to start a car in cold weather.
Attempts to start the engine should last no longer than 5 seconds, otherwise you will completely drain the battery. In addition, the winding in the starter may burn out. Another problem is the wear of the bendix. Rewinding the starter windings or replacing the gear will cost a significant amount. If the engine fails to start after three attempts, take a minute off to allow the starter to cool and recharge the battery.
If you feel that the engine is about to seize, but something is missing, try to help a little with the gas pedal. You shouldn't do more than two light strokes, otherwise you will fill in the candles, then you definitely won't go anywhere. You will have to dry these elements of the ignition system.
3. How to properly start a car in cold weather by “lighting up” from another car
This advice how to start a VAZ in the cold or car another brand with a carbureted engine, in case all attempts were unsuccessful, and the batteries are almost at zero. Ask to "light up" - start from someone else's battery. It is useful to have wires with "crocodiles" - in this case, passing drivers are more willing to agree to help.
Strictly observe the polarity: minus to minus, plus to plus, otherwise you will ruin both batteries. You need to disconnect the battery in the following sequence - first remove the negative "crocodiles", then open the positive ones.
When the car is started, do not turn off the engine immediately. Drive it for about three minutes, attached to someone else's battery, so that the antifreeze and oil in the crankcase warm up. Don't step on the gas too much to load the generator.
4. How to start a VAZ or another brand of car in the cold “from a pusher”
well and how start the car in the cold if there is nowhere to "light"? There remains a radical method. It is necessary to ask neighbors in the parking lot or passers-by guys and men to help start the engine “from the pusher”. Put the third gear and try to "revive" the engine while the assistants push the car.
Important: The “push” start method works flawlessly only for cars with manual transmission, it is impossible to start an “automatic” like that!
Poor quality fuel is evil
If the engine does not start despite all attempts, then the problem may lie in low-quality gasoline. Some gas stations may add water to the fuel. This is fraught with the formation of condensate.
Condensate freezes in the cold and can block the fuel system. The exhaust pipe has already been mentioned - this is the most easily removable obstacle. Condensation can freeze on the fuel line grate in the gas tank. In this case, you will have to tow the car into a warm box so that the frozen condensate melts.
In order not to get into such a situation, refuel at proven gas stations. Try to always keep the tank two-thirds full in winter. The less empty space in the gas tank, the less condensation forms.
How to start a car with an injector in the cold
The main reasons why it is difficult to start an engine with fuel injection at temperatures below -20 ° C are the same as for carbureted counterparts:
- reduced battery power;
- thickened oil;
- condensate frozen in fuel system.
In an injection engine, the fuel supply is regulated electronic unit management. This is the main difference between the direct injection system and the carburetor scheme.
1. Battery preparation
We act exactly as described carbureted engine: we flash the main beam, squeeze the clutch and try to start the engine with short turns on the ignition. Only suction is not required - the flow of gasoline is regulated by the ECU.
BUT how to start a car in cold weather? We do everything in the same way, but do not squeeze the clutch. On a car with automatic transmission, there is simply no such pedal. The starter has to rotate the shafts and gearbox disks together with the engine, but there is no other way. The selector lever must be in position P.
2. How to start the machine in the cold if the ATF liquid is frozen
In extreme cold transmission fluid in automatic transmission it becomes so viscous that it becomes necessary to warm up the car with external devices. The best option- use a heat gun. Some craftsmen use a blowtorch or a torch, but this is fraught with fire.
3. How to start the injector in the cold using the "lighting" method
"Smoke" the car with injection engine need to be careful. There is a danger of burning the ECU, which has adapted to the amperage, internal resistance and other parameters of the native battery. You can’t just throw wires from a third-party battery onto your batteries and start the engine.
We act according to the algorithm:
- We remove the wires from the battery.
- We connect the wires from the car that gave a "light".
- We are waiting 10 minutes.
- We remove third-party wires.
- We connect the "native" battery to the car's network.
- We start the engine.
Of course, this is more difficult and longer than directly “lighting up” from a running machine. It is better to make more efforts than to risk the "health" of the on-board computer.
How to dry flooded injector spark plugs
If the engine starts and immediately stalls, then during previous unsuccessful attempts, you filled the candles with gasoline. When you step on the gas, the electronics react to the throttle position. The computer thinks you want to speed up and sends more fuel to the injectors to richen the mixture.
To clean spark plugs from gasoline, you need to throttle valve opened all the way, but no fuel was delivered to the injectors. We turn off the fuel pump from the power supply by removing the fuse - there is nothing to pump gasoline with, and air is supplied through the throttle. If the injectors and the fuel pump are powered through the same fuse, disconnect one terminal of the fuel pump.
Turn on the ignition to start the engine. As soon as the engine starts, put the fuse in place. Now you can calmly accelerate, but not much - you should not load cold engine. One start of the engine in the winter cold can be compared in terms of damage with 200 - 500 kilometers at the optimum temperature. Shouldn't be exacerbated.
How to start an injector in cold weather from a pusher
If there is no one to “light it up”, or this operation did not lead to the desired results, there remains a radical method - “from the pusher”. How to start a car with an injector in the cold"from the pusher"? We ask neighbors in the parking lot or passers-by to push the car, set the third gear and turn on the ignition in time. Do not forget that this way you can start a car only with mechanics - automatic transmission under such actions breaks down.
How to start a diesel in cold weather
The main difficulty when starting a diesel engine is the low temperature of the fuel and air in the cylinders. In the internal combustion engine of this system, the fuel ignites due to strong heating when air is compressed by a piston. Strong cold creates obstacles to the detonation of fuel - it does not have time to heat up. How same start diesel in cold weather? The amount of effort expended depends on the condition of the car and the position of the thermometer.
1. Warm up the glow plugs
First of all, we try to simply warm up the glow plugs. When the ignition is turned on, voltage is applied to the candles, and they heat up, at the same time heating the air in the combustion chamber. Repeat this procedure three or four times when start in severe frost diesel engine.
2. How to start a diesel engine in cold weather if there is no fuel supply
If the starter vigorously turns the shaft for 8-10 seconds, and the engine does not want to start, then there is no fuel supply. Obviously there is a blockage in the fuel system. When diesel fuel freezes, the paraffin in it crystallizes, forming dense clots. These pieces clog fuel lines and filters.
In winter, be sure to use only winter diesel fuel. If extreme cold is expected, it is recommended to add special depressant additives to the fuel, strictly following the instructions. These anti-gels prevent paraffin crystals from sticking together, but cannot dissolve them.
If you missed the moment and the paraffin has already hardened, you will have to work hard. In this case, fuel heated to approximately + 40 °C should be added to the tank in the same volume that is already there. Even better if there is more hot diesel fuel. The heated fuel will dissolve the paraffin crystals, and the additives added in advance will prevent them from forming again.
How to start an automatic car in the cold with diesel? Just like with mechanics. The only difference is that in a car with automatic transmission, you do not need to depress the clutch at start-up, and you cannot start by towing or “from the pusher”.
