Why do most Volgas have huge fuel consumption? How to reduce consumption on the Volga? Gas 24 Volga consumption.

The history of the famous Volga car begins in 1956. For a long time, this car was a symbol of the Soviet era and the dream of millions of citizens. And it so happened that the flagship of the Gorky Automobile Plant was both an incentive to move forward and a burden for the enterprise to reach new heights.

The first car under the proud name of the mighty Volga River bore the GAZ 21 index. Having left the assembly line, it immediately received the status of a symbol of that time. The car was constantly filmed in films, successfully exported, received prestigious awards at car shows around the world. This model became, without much exaggeration, the first premium car that a simple Soviet citizen could afford. Especially considering the fuel consumption per 100 km, which was significantly lower than the competitors' cars produced at the same time.

By the way, the Volga became the first model that could be equipped with automatic transmission, which was considered an unprecedented "bourgeois lotion". It was, in truth, an outstanding and very successful car, which received the status of a cult, and is still often remembered with enthusiasm by connoisseurs of the classics. Too bad things didn't go according to plan...

Fuel consumption GAZ-24-10

In the wake of the success of the 24th Volga, it was decided to carry out a deep modernization and launch a new car into large-scale production. The first car GAZ 2410 was produced at the end of 1985. This model belonged to the middle class. It is worth noting that the novelty received from its predecessor not only moderate fuel consumption, but also high build quality, as well as a reputation for increased reliability. In addition to the standard sedan version, modifications were made to work in a taxi service, an ambulance, as well as a station wagon model. In each of the above types of car, the same power unit, whose fuel consumption is shown in the table.

GAZ-3102

The model, known as the GAZ-3102, is also a middle-class car, the release of which started on New Year's Eve 1982. This machine was developed on the platform of the most popular 24 model and was supposed to be its successor. But everything did not go so smoothly, and for many economic and even political reasons, the Volga 3102 was produced in small batches, amounting to no more than three thousand copies in one calendar year.

The characteristics and consumption rates of gasoline of the model made it possible to use it as a means of transportation for middle-level Soviet officials, that is, for those people who, according to their status, were not entitled to Chaika limousines. By the way, in model range 3102 engine options were much more than 24. The fuel consumption of the Volga per 100 km can be found in the table.

Fuel consumption GAZ-3110

Since the end of the 80s. representatives of the car factory constantly talked about the imminent appearance of a new model. True, words, for some reason, always disagreed with actions.

And so, in 1997, the company decides to restyle model 31029. The novelty is published under the index 3110.

However, nothing new, with the exception of the modified 402 and 406 motors, new car could not boast. All other declared options were available on the previous model. Only exterior differences were striking. Although the refinement of the steering has benefited: now the car has become soft and supple to drive.

Fuel consumption GAZ-31105

The appearance in the lineup of the new GAZ-31105 was more of an attempt to change at least something, since the car practically copied the version with the index 3110. The list of improvements includes a pivotless front axle suspension, the appearance of a stabilizer roll stability in rear suspension, as well as a modernized checkpoint. To the credit of the design department of the plant, work on the exterior of the Volga 31105 was carried out extensive and painstaking: in place of the front angular headlights, modern analogues in the form of drops appeared, the radiator grille, front fenders, bumper and hood were replaced.

In the period from 2006 to 2007, the company worked on the release of model 311055, which received an extended wheelbase. However, the business class version was made to order and did not go on mass sale.

Volga Cyber

The company needed to be urgently saved with the release of a new model. For these purposes, it was decided to borrow a licensed front-wheel drive platform from the auto giant Chrysler. So in 2001, the production of the model was launched. Volga Siber, which was designed by the famous British studio UltraMotive. During the design of the Volga Siber, the goal was to apply to the maximum the existing developments of American automakers. Wherein domestic car was supposed to have classic exterior features familiar to many.

It is worth saying that, like many cars, the fuel consumption of the Volga for a hundred kilometers in winter is slightly higher than in summer, this must be taken into account before making personal measurements.

The 24D model engine has a high compression ratio of 8.2. For its normal operation, it is necessary to use gasoline with an octane rating of at least 85 units (according to the motor method), i.e. AI-93 or "Extra" gasoline. Gasoline AI-93 - leaded, it is colored blue. It should be remembered that leaded gasoline is poisonous and requires special rules when handling it. Avoid contact with leaded gasoline on the skin of hands, clothing and body upholstery. Particularly dangerous consequences are caused by the ingress of leaded gasoline into the respiratory system or into the oral cavity.

The use of gasoline with a lower octane number (A-76 and even more so A-72) is completely unacceptable for the 24D model engine.

The Model 2401 engine uses A-76 leaded gasoline, painted green.

Gasoline consumption GAZ-24 Volga

Volga cars have high efficiency, which, however, is achieved only with the correct installation of the ignition, fine adjustment of the carburetor, the use of oils of the specified viscosity for the engine and transmission, the correct adjustment of the front wheel bearings and maintaining normal air pressure in the tires.

Efficiency also depends to a very large extent on the correct driving techniques. Fast driving with sharp acceleration and frequent braking increases gas mileage.

Fuel consumption largely depends on the operating conditions of the car and the qualifications of the driver. Fuel consumption is also affected by speed, load, road surface condition, terrain, air temperature, driving techniques, etc.

With increasing speed, fuel consumption changes in a certain relationship ( rice. 230 ). As seen on rice. 230 , the minimum consumption is obtained at a speed of 35-45 km / h. If possible, choose the most economical driving speed.

Driving on country and cobblestone roads, as well as on city streets with frequent braking and stopping, inevitably increases fuel consumption. Fuel consumption at winter operation increases by 10%. Particular attention should be paid to the technical condition of the car, which has a decisive influence on the efficiency of its operation. In order to increase economy, the following is recommended:

1. Correctly adjust undercarriage and, first of all, the front wheel bearings.

2. Apply lubricants of the required viscosity in accordance with the manufacturer's instructions.

3. Maintain the air pressure in the tires according to technical specification.

4. Correctly adjust the convergence of the front wheels.

5. Precisely adjust the parking brake actuator.

6. Use AI-93 gasoline or "extra" gasoline for the 24D engine and A-76 for the 2401 engine. In the case of using gasoline with a lower octane number, the engine runs with detonation, and when a later ignition is installed, gasoline consumption increases.

7. Correctly set the ignition and check its setting while driving. A small amount is recommended early ignition so that when you sharply press the throttle control pedal at a speed of 30-40 km / h, a slight, quickly disappearing detonation is heard. Driving with constant detonation, including with increased load (on slopes, on sand, etc.), is unacceptable.

8. Precisely adjust the carburetor, especially the RPM idle move and the fuel level in the float chamber. The fuel level is adjusted by bending the tongue on the lever, to which the float is soldered (see Fig. 51).

9. Use the candles specified in the technical specification, adjust the gap within 0.8-0.9 mm, replace the candles with new ones in a timely manner (after a run of 20-25 thousand km).

10. Monitor the tightness of the fuel line connections, avoiding fuel leakage.

11. Maintain the temperature of the coolant within 85-90 ° C. It is recommended to close the blinds at stops and move off without opening them. In winter, additionally cover the radiator lining with a warm cover.

12. Maintain economical driving speeds. Make good use of the terrain and road conditions.

A fully run-in vehicle with a properly adjusted running gear must roll freely on a flat asphalt road at a speed of 50 km/h until a complete stop of at least 500 m. 35-45 km / h should be within 8-8.5 liters per 100 kilometers.

The dependence of gasoline consumption on a flat asphalt road on the speed of movement is shown in rice. 230 .

The actual gasoline consumption of a GAZ-24 car with a ZMZ-24D engine at speeds of 80-90 km / h is:

On the highway - 11.5 - 13.0 liters. per 100 km.

In the city - 13 - 15 liters. per 100 km

High dynamic qualities and good stability of the car, combined with a soft elastic suspension, allow you to move at high speed like on good roads asphalt, and on roads with significant roughness. However, it should be borne in mind that, although the driver and passengers, when driving on bad roads, hardly feel road bumps, the resulting load is still fully perceived by the chassis. part of the car, causing accelerated wear on the suspension and bodywork. In particular, high speed cornering should not be allowed, as this leads to rapid tire wear.

The temperature regime of the engine also affects the efficiency of the engine and the wear of its parts. The temperature of the liquid in the cooling system must be maintained within 85-90 ° C, avoiding movement with a cold or insufficiently warm engine. The temperature in the cooling system is controlled by a thermostat and the degree of opening of the blinds. In winter, when the ambient temperature is low, the blinds must be completely covered and a heat-insulating cover should be put on the radiator lining.

It must also be borne in mind that during the engine warm-up, the thermostat in the cooling system is closed, water does not circulate through the radiator and can freeze in it, although it will be warm in the engine jacket. When the coolant temperature rises above the permissible limit, a red signal lamp lights up on the instrument panel.

In this case, it is necessary to check whether the blinds are open enough. If the lamp still does not go out when the blinds are open, then you need to stop the car and eliminate the causes that caused the engine to overheat. Overheating may be due to excessive overlap of the valves of the insulating cover, insufficient amount of liquid in the cooling system, weakening of the fan belts, etc.

The warning light sometimes comes on immediately after the engine has stopped running under heavy load, due to the interruption of fluid circulation in the cooling system. In this case, the movement can be continued without waiting until the lamp goes out. After starting the engine, circulation in the cooling system resumes and the lamp goes out.

Driving with an overheated engine is not recommended, since "this dramatically reduces the viscosity of the oil in the lubrication system, which leads to a reduction in the service life of the connecting rod main bearings of the engine.

Drain the water from the cooling system through two taps at open traffic jam radiator. In addition to the cooling system taps on the lower radiator tank and on the cylinder block, the heater tap must be open with right side engine (on the cylinder block in the area between the third and fourth cylinders).

AT very coldy it is recommended to cover the openings in the radiator shields with cardboard or rags, since the through flow of cold air greatly cools the oil in the steering mechanism and the brake fluid in the brake master cylinder, hydraulic vacuum booster and separator. Increasing the viscosity of the oil and brake fluid increases the force on the steering wheel when turning the car and on the brake pedal when braking.

Heating combustible mixture in the intake pipe, especially necessary in winter, is carried out with the help of exhaust gases that heat the intake pipe in its central part. A damper is installed in the cavity of the exhaust pipe at the place of its attachment to the inlet pipe, with the help of which the direction of the exhaust gases and the degree of heating are changed. The damper can be set in two basic positions: for summer and for winter; it is recommended to change the damper position in spring and autumn according to the coming season.

An oil cooler is installed in the GAZ-24 lubrication system. In summer (when the air temperature is more than +5 ° C), the radiator must be turned on. In winter (when the air temperature is below +5°C), the radiator should be turned off. To turn on the radiator, the handle of the valve located on the left side of the engine must be turned along the pipeline, to turn it off - across.

The engine oil is cleaned by a single full-flow filter with a replaceable filter element, which must be replaced every time the oil in the crankcase is changed. A slight darkening of oil containing additives is not a reason to change the oil or filter element.

in crankcase rear axle it is necessary to fill in only special oil for hypoid gears cars according to GOST 4003-53. Filling or adding any other oil, including hypoid oil for trucks according to TU TNZ 128-63, renders the main gear gears unusable.

AT brake system car mounted hydro vacuum booster, which comes into operation when the pedal stroke corresponds to the force on the pedal platform of 3.5-4 kgf. When the pedal is pressed further, the hydrovacuum booster has an auxiliary effect, providing the necessary braking efficiency with a relatively small effort of the driver's foot. Therefore, it is recommended to press the brake pedal smoothly, without much effort.

When the pedal is pressed hard (jerky), the pressure in the system after the hydrovacuum booster comes into action quickly increases, causing too sharp braking and even blocking of the wheels. Hard braking is especially dangerous on slippery roads. It should be borne in mind that in winter, due to an increase in the viscosity of the brake fluid in the system, the hydrovacuum booster comes into action with more effort on the pedal than in summer, and therefore more attention is required when braking.

Separator included in brake system, provides sufficiently reliable braking in case of failure of part of the braking system (front or rear brakes), but you can continue to move only in exceptional cases and with precautions.

The brake and clutch release systems should only be filled with brake fluids(BSK or ASK), made on vegetable oil. The use of liquids containing mineral oil and designed for oil-resistant rubber, for example, petroleum hydraulic brake fluid GTN, is strictly prohibited.

Sidelights and rear lights of the body have housings made of plastic with decorative metallization. Contact with gasoline or solvent is not allowed, as it causes clouding and cracking of the plastic.

Machine lock

To prevent the engine from starting and stealing the car by unauthorized persons, the ignition key should be turned 90 ° counterclockwise, which not only turns off the ignition, but also locks the steering wheel. In this case, the front wheels should be put in the position of driving in a straight line. When unlocking the anti-theft device, it is recommended to simultaneously rock the key while turning the key. wheel round trip.

The buttons on the door panels in the pressed position block the lock drive both from the outside and from the inside. When the button is pressed, the inner handle of the lock is motionless. Keep the covers of their switches closed at all times to avoid contamination of the mechanisms of the door locks, the trunk and the hatch of the petrol tank. The use of the radio in the parking lot with the engine off with the ignition on is not allowed, as this can lead to overheating and damage to the ignition coil. To avoid draining the battery, it is not recommended to use the receiver in a parking lot for more than three consecutive hours.

It is strictly forbidden, even for a short time, to connect terminals III of the generator and voltage regulator to ground (for example, in order to check for a "spark"), as this may damage the voltage regulator.

The car is designed to carry 5-6 people and 50 kg of cargo in the trunk. The sixth seat with limited facilities is for short trips only.

It is allowed to carry cargo in the trunk up to 100 kg, but only on good roads and under the condition of driving at a reduced speed. Overloading the car, especially when operating on bad (dirt, cobblestone and unimproved highway) roads, inevitably leads to a reduction in the life of the car.

It is recommended to start off only in first gear, and while driving, switch to downshifts without excessive loss of speed. This protects the transmission parts and especially the clutch from excessive loads and increased wear. It should also be borne in mind that the engine has better traction and throttle response when operating at a higher speed.

Special instruction. Engine exhaust gases contain poisonous products of fuel combustion, including carbon monoxide (a colorless and odorless gas), which, if inhaled, can cause severe poisoning and, if exposed for a long time, can even be fatal. Therefore, long-term operation of the engine in the garage without special exhaust devices should be avoided. It is also not recommended to turn on the ventilation of the body in the parking lot with the engine running.

The Volga car has had a reputation as a voracious monster ever since Soviet Union. And indeed, despite factory numbers of up to 10 on the highway and up to 14 in the city, often real numbers significantly exceed the indicated figure, sometimes by 50%, and in especially neglected cases by 100%.

So what affects fuel consumption on the Volga, and how to reduce it?

All factors that affect fuel consumption are divided into those related to the engine and not related to the engine. In the first case, a serviceable and tuned engine is forced to overcome increased resistance to movement. In the second case, the engine does not work optimally due to a malfunction of its individual systems.

Consider engine problems affecting fuel consumption.

problems with the ignition system

malfunction of the ignition system. here the ignition distributor (distributor) is most often to blame. the fact is that the contact distributor is very sensitive to the cleanliness of the contacts, the adjustment of the gap, and especially to the axial transverse play. If there is a lateral play, it is IMPOSSIBLE to set the gaps in the contacts and the engine starts poorly and runs poorly, sooner or later it will stop working altogether. From a faulty distributor, the consumption can soar by 2 times, since misfiring, not optimal combustion significantly impair engine performance. It is ideal to replace the ignition with electronic. Its price will more than pay off with confident launches and stable fuel consumption.

incorrect gap in the spark plugs. too small a gap, although it prolongs the life of the contacts, but worsens the combustion of fuel. Excessive clearance leads to burnout of the contacts and, accordingly, to an increase in consumption.

soot on candles, faulty punched candles. like all malfunctions in the ignition system, faulty candles increase consumption, and when they die completely, the engine usually does not start, or starts very poorly.

incorrect adjustment of the ignition timing. if the ignition is later, fuel consumption increases, and there is also a risk of valve burnout. the ignition must always be adjusted to the knock threshold. Those. on the Volga at a speed of 40-50 km / h in 4th gear with a sneaker on the floor, detonation should be clearly audible. For gas UOZ is set for propane +7 from the 92nd gasoline, for methane +15 from gasoline (set at the detonation threshold).

carburetor problems

the carburetor as the main metering system of the engine often makes its own adjustments to fuel consumption. the main problem of the native Volgovsky carburetor K-126G is leakage, which leads to fuel leaks both outside and overflow into the engine.

valve problems

insufficiently large clearance in the valves leads to a decrease in engine compression, naturally decreases efficiency and, accordingly, fuel consumption increases. Always set the optimal clearance of 0.4-0.45 mm and only for the outer valves can be set to 0.35-0.4. On gas fuel, it is better to increase the gaps by another 0.05 mm.

burnt, cracked, non-lapped valves also naturally reduce compression and, accordingly, engine performance deteriorates significantly. in especially neglected cases, a cylinder with a valve defect stops working and simply spits out the fuel, and sooner or later it explodes in the muffler, spreading it to pieces. Therefore, if the engine troit (for any reason), do not continue driving, but check the ignition, and if it cannot be eliminated, it is better to call for help in tow or a tow truck. Even a kilometer on a triple can lead to an explosion of fuel assemblies in a silencer. Especially in the urban cycle when the engine cannot blow all the fuel into the pipe.

compression and general engine condition

the normal compression of the Volgovsky engine for 92nd gasoline is 13-14 atmospheres. With compression less than 10 atmospheres, overhaul. I advise you to measure the compression at each replacement of spark plugs (and unscrewing them for cleaning, adjusting the gap). Compressometer for gasoline engines It is not expensive, although this procedure is best done with an assistant. Compression is measured with the engine warm.

Consider other problems and nuances affecting fuel consumption

brake related problems

the brakes of the Volga car, especially the GAZ-24 models, are "abstruse" and not optimal. What is the problem? And the fact that they like to wedge. And they do it for different reasons. So there may be a faulty check valve for adjusting the residual pressure in the brake system (located in the GTZ), the coupling springs may be stretched, or the bearing fingers of the brake pads may turn sour, which will cause them to seize. Naturally swollen cuffs in the hydraulic vacuum booster (including its control valve), in the working and main brake cylinders, and the divider contribute to poor wheel release. In general, I strongly recommend that anyone who does not pursue originality install a normal vacuum amplifier. You can install a system from GAZ-2410, or foreign cars. Decide for yourself what you prefer. But the vacuum cleaner from the GAZ-2410 has the property of "za****t" and does not slow down. But he understands and the cuffs can be replaced, though the procedure is not easy. I installed a new one, while the flight is normal like.

running gear problems

overtightened wheel bearings, incorrect wheel alignment increase fuel consumption

deflated tires are one of the most common causes of increased consumption, in the end buy a normal pressure gauge and pump, and do not be lazy to check the pressure at least once a week. there are also caps with a control function.

transmission related problems

slipping clutch increases fuel consumption

too thick oil that does not meet the requirements of the plant in the bridge and box leads to a sharp increase in fuel consumption, this is especially noticeable in winter.

overloaded with stuff

the trunk in the Volga is large and many carry a bunch of rubbish and heavy tools there. think about whether you need 4 sets of keys and two jacks or 2 spares? every extra kilo is an additional expense. Many people throw a sandbag into the trunk in winter ... better install, they are still allowed in the CIS.

harsh driving style

The Volga is a heavy car, and "sporty" driving increases fuel consumption in a dramatic way.

don’t start it, or maybe something on the hodovka, the bearings can rub, maybe brake pads, collapse ...

Answer from Glushko Andrey[guru]
change the oil in the box and gearbox - in winter it will slightly reduce consumption, pump tires back to normal

Answer from Ludmila Ukrainian[newbie]
the whole thing can be in kilometers, if they are driven in first gear!

Answer from Garik Dobermanych[guru]
Valves - definitely - "do not play" - A large gap is not a shame! =)
Look at the ignition...
Although the neighbor on the "Volga" - the consumption is approximately comparable to yours .... well, maybe 1-2 liters back / forth ...
I don’t believe in the consumption of 9 liters on the Volzhan - fairy tales! - or clamped so that not only the second, but also the first chamber - does not breathe! =)))

Answer from Yury Bobrov[guru]
consumption on the Volga depends very much on the ignition setting, on these engines it is better to set the ignition not according to the grid, but according to the appearance of detonation knocks, when accelerating the car into 4 gears from a speed of 40 km, a slight detonation should be heard
