Kia-Hyundai G4FA engine

Characteristics

Malfunctions and repair of the G4FA 1.4 l engine.

The G4FA engine belongs to the Gamma series, which was released in 2006 and replaced the outdated Alpha engines. The Gamma includes a number of engines, the most famous of which are the 1.4 liter G4FA and the 1.6 liter G4FA. G4FC, assembled on a single cylinder block, but we will focus on the younger representative.
The engine is based on an aluminum cylinder block with cast-iron liners, in which a crankshaft with a piston stroke of 75 mm, long connecting rods, pistons with a kind of displacer and a height of 26.9 mm are installed with an offset of 10 mm.
This block is covered by an aluminum 16-valve head with two camshafts. The Solaris / Rio 1.4 engine is equipped with a variable valve timing system, but only on the intake shaft, in addition, there are no hydraulic lifters on the G4FA engine, so valve clearances must be adjusted every 95,000 km if the situation requires it.
Compared to older Alpha series motors, the G4FA uses a timing chain with a tensioner that does not require maintenance throughout its official life. Indeed, in practice it is quite reliable.
A single-stage ordinary receiver is installed at the inlet, without various length change systems.

In addition to well-known cars Hyundai Solaris and Kia Rio this engine It is also installed on Kia Cee'd II, i20 and other vehicles in a slightly derated version - by 100 hp.
On the basis of the G4FA motor block, a 1.6 liter engine of the Gamma series - G4FC was also developed. Later, other close motors appeared: G4FG, G4FD, G4FJ and L4FC.
The release of the engine was discontinued in 2018 and is now being replaced by a 1.4-liter version from the Kappa family.

Problems and disadvantages of KIA-Hyundai G4FA engines

Many are interested in which manufacturer of the Hyundai Solaris / Kia Rio engine, and so it is produced by the Beijing Hyundai Motor Company, but the engine is Chinese, but do not rush to shout “garbage / fall apart / junk ...”, let's take a clear look at the shortcomings and main malfunctions of the G4FA, and then let's conclude:

1. Knocking in the Rio or Solaris engine. If your warm-up knock disappears, then most likely it is the timing chain that makes noise (in 90% of cases) and there is nothing to worry about, if it is also heard when it is hot, then the problem may be in unadjusted valves, they can also be adjusted incorrectly on factory. Contact the service and put them in order.
2. Noise. Sounds reminiscent of clicks, clatter, chirping, etc., are normal work nozzles and otherwise they do not know how.
3. Oil leaks. Not often, however, the valve cover gasket is not perfect and traces of oil are signs of this. Change the gasket and drive on without problems.
4. RPM fluctuates, uneven operation of the Rio/Solaris engine. The problem is solved by cleaning the throttle valve, if it did not help then fresh firmware.
5. Vibration on idling. The cause of this phenomenon is dirty throttle valve or candles. We clean the damper, change the candles and enjoy the pleasant operation of the motor. In case of strong vibrations, look at the engine mounts.
6. Vibrations at medium speeds. This happens at about 3000 rpm and no one knows what is the reason, official dealers Hyundai-Kia talk about engine features and rightly so. At these speeds, the G4FA motor comes into resonance and, thanks to the peculiar design of the engine mount, all the vibrations are on your steering wheel and wherever possible. Give the gas or release the pedal, the motor will go out of resonance and the vibrations will disappear.
7. Whistle. A sore subject, the whistle appears due to the weak tension of the alternator belt, change the tensioner pulley and everything disappears.
8. Eats oil. The problem has been with motors since 2011., these power plants do not have a very reliable catalyst, and due to poor-quality fuel (especially for regions), it tends to fail after 50 thousand km. In the process of its death, ceramic dust enters the cylinders and forms scuffs in the cylinders. As a result, we have high oil consumption and the need to overhaul the block sleeve. Solution: either pour very good fuel, or knock out the catalyst.
This problem does not affect the first engines with exhaust manifold"ram's horn".

Despite the declared motor resource (at least 180 thousand km), over the years of operation, these motors have shown themselves very well, they have a resource of at least 300 thousand km. The main thing is timely maintenance and the use of good oil.

Engine number G4FA

The engine number is stamped on the cylinder block near the junction of the gearbox and flywheel.

Engine tuning Hyundai-Kia G4FA

Chip tuning G4FA

One of the fastest, easiest and cheapest ways to increase power is to recalibrate the engine. The offices promise 110-115 hp after the chip, try it for the sake of experiment, but don't expect significant changes. It's better to see what sensible things can be done with your motor.

G4FA 1.6

A more effective tuning option is to increase the volume of the G4FA to 1.6 liters. You don't need to change the cylinder block to pull off this scam, it's the same as on the 1.6L engine, the heads are the same except for the intake camshaft.
To assemble the stroker you will need a G4FC crankshaft with 85.4mm stroke, G4FC short connecting rods and G4FC pistons (they are recessed to reduce compression). After installing all this, you need to flash the ECU. For a full G4FC conversion, add a G4FC intake camshaft to that.
All this will give a typical 123 hp.

To go even further and get 130+ hp, you need to install a variable geometry intake manifold from a G4FG. To do this, you will have to spend a little effort and money on the receiver, the VIS system control unit and the probe from the G4FG with a guide.
If we are talking about the G4FG, then its intake camshaft will be meaner and, with certain modifications, it will fit on your engine.
To all of the above, you can add a cold inlet, a normal 4-2-1 spider and an exhaust on a 51 mm pipe. After tuning, all this stuff will give you about 140 hp.

It is useful for owners of budget vehicles to find out the features of power units installed on Kia cars Ria.

The upcoming study focuses on the advantages and disadvantages of these engines, recommendations for proper maintenance and maintenance. The proposed publication will help determine the appropriate fuel and oil.

What is bad and what is good about the Kia Rio engine.

Adviсe owners for proper care

Not every driver can afford a business class car from leading European manufacturers.

Most are content with little, choosing domestic cars.

There is another a budget option provided on Russian market Korean automotive suppliers. This article will tell you what the engine is in reality Kia Rio, and what measures will help the owner to maintain the original characteristics of the unit for a long time.

Characteristics of the power plant Kia Rio

Korean manufacturers have taken care of the convenience of Russian motorists. Their creation is great for domestic roads. This is facilitated by the following characteristics of the power unit:

• the possibility of refueling AI-92 gasoline. For most budget owners vehicle the issue of saving is in the first place, so the use of cheap fuel is important;
• in difficult conditions Russian roads very useful is a special anti-corrosion compound, protecting the bottom of the body from the effects of domestic dirt;
• harsh climate is not a hindrance to starting the engine. The developers have provided the ability to start the engine at temperatures up to -35 C. Therefore, the car has proven itself perfectly even in the conditions of the northern regions;
• domestic public utilities are struggling with the icing of winter roads, generously sprinkling them with salt. Korean manufacturers secured the radiator, protecting it with a special composition that protects against such troubles.

It should be noted that the Kia Rio provides for the installation of power units two types differing in volume and power. Each of them requires separate consideration.

Features of the 1.4-liter Kia Rio engine

To begin with, we note that this power unit is basic. Its characteristic is the ability to 6300 revolutions per minute to develop engine power, considered equivalent 107 Horse power. Given the use of AI-92, this is a very good indicator. Mechanical transmission allows for just 11.5 seconds for a car to reach a speed of 100 km/h.

On an open track, such an engine consumes only 4.9 l fuel. Driving on city streets increases the absorption of gasoline to 7.6 l. Movement in the combined cycle is characterized by fuel consumption in 5.9 l.

In another measurement system, 1.4 l corresponds to a volume of 1396 cm3. The engine has four active cylinders. Each of them has 4 valves. The working stroke of the piston is determined by the value 75 mm inside a cylinder with a diameter of 77 mm.

Fully using the resource of the Kia Rio engine, the driver is able to reach speeds of up to 190 km / h. Such indicators are very acceptable for domestic motorists who prefer fast driving at minimal fuel costs.

Features of the 1.6-liter engine

The relatively small volume, however, allows the power unit to develop engine power comparable to the efforts 123 frisky horses. This allows the driver to feel unshakable confidence in the reliability of the vehicle.

Personally, I pour into the gas tank of such an engine exclusively AI-95. In this case, saving by refueling with cheaper fuel is very unwise, since this can negative to impact on performance characteristics motor for Kia Rio.

Another distinctive feature of the engine that equips the Kia Rio is timing drive, represented by a chain mechanism. This greatly simplifies the replacement process and increases the durability of the device. Although the timing chain contributes to an increase in some driving rigidity and noise in the cabin, these shortcomings are fully offset by an increase in the reliability and endurance of the power unit.

When driving around the city, a 1.6-liter engine consumes approximately 8 l fuel. If you intend to travel on an open highway, fuel should be poured into the tank at the rate of 5 l. It is somewhat more difficult to determine how much gasoline will be needed when driving on a combined type of terrain. Experienced drivers for mixed cycle stock 6.6 l.

The dynamic performance of the engine is similar to the previous model. Only the piston stroke and cylinder diameters differ. For power plant 1.6 liters they are 85.4 and 87 mm, respectively.

1.6 liter engine flaws

Possessing a sufficient number of positive characteristics, the considered motor model also has quite significant flaws. They deserve special mention:

• limitation space engine compartment at enough large sizes engine makes access to some nodes very problematic. Therefore, it is possible to repair certain parts only after additional dismantling of the power plant;
• since the temperature of the engine in operation is quite high performance, problems may arise due to the material of manufacture of the cylinder head. As you know, aluminum does not tolerate thermal surges. However, this flaw is compensated by the output performance of the technological alloy;
• ignition and gas distribution systems must be replaced only in set. It simplifies overhaul engine, reducing labor costs, but making it impossible to partially replace the parts of these mechanisms;
• perhaps the most significant drawback of the considered power units is considered low maintainability. Even professionals of specialized services with great reluctance take on major repairs after damage to the main components.

These shortcomings do not detract from the undeniable advantages of this motor. They are also worth considering in more detail.

The advantages of the power unit 1.6 l

Most modern motorists prefer to buy cars with just such an engine. The selection takes into account the following positive sides characterizing the motor:

• saving due to lower fuel consumption. Moderate driving on the combined cycle route requires only 6 liters of fuel. Personally, I have always poured gasoline from this calculation;
• attractive is the extreme reliability of the main functional units, ensuring trouble-free operation of the engine of the Kio Rio sedan for more than 200 thousand kilometers;
• high dynamism, characterized by the ability to accelerate to 100 km / h in just 10.3 seconds;
• optimal distribution of performance between the engine and transmission creates an excellent elasticity of the power plant. This instills confidence in the driver in the most difficult traffic situation.

Despite some difficulties caused by the impossibility partial replacement certain elements of the gas distribution mechanism and the ignition system, for professional mechanics of specialized service shops, repair of the Kia Rio engine is quite business as usual. The cost of such services is also considered quite acceptable.

The exclusivity of the resource of the power unit is confirmed by car owners who over a five-year period have overcome over 300 thousand km. The remarkable fact is that the sedan did not show any tangible problems with the engine.

The manufacturer provides for the need for technical inspection after passing every 10 thousand km. Even middle-income car owners may well afford to use the services of specialized workshops. The affordable cost of maintenance is due to the simplicity of the design of the power unit.

There are several secrets that can increase the life of the motor:

• The lifespan of a vehicle depends largely on what kind of oil is poured into the engine Kia Rio. It is recommended to choose brands verified producers, certainly taking into account the seasonality of the oil product. It also needs to be updated regularly. motor oil for Kia Rio, be sure to replace oil filter. Manufacturers have set the maximum mileage on the same lubricant, determined by 15,000 km. However, experienced drivers try to change the oil product every 7000 km;
• gasoline should only be poured into specialized gas stations. This will help eliminate the use of low-quality fuel. Cheap counterfeit fuel can quickly disable a completely serviceable power unit;
• The last piece of advice concerns driving style. Calm measured ride save the car much longer than recklessness.

look interesting video on this topic:

Back in 2000, Kia Rio was born in order to replace the already outdated Kia Avella, which was not distinguished by high reliability or quality. Kia lovers needed a car to get around the city. For this reason, manufacturers have released Rio in order not to let buyers around the world.

First of all, the presentation took place in Geneva and Chicago, the audience was presented with a sidan and a hatchback. Rio was different modern design, comfortable interior and a number of trim levels, which had an optimal ratio of quality and price for that time, which captivated the public.

The second generation, produced in 2005, fully complied with European standards. As a result, the price also increased. Produced for five years (2006, 2007, 2008, 2009, 2010). A version was delivered to Russia in which the engine capacity was 1.4 liters, but a choice was given: mechanics or automatic.

The third generation of 2011 release remains relevant to this day. A new version Kia was intended for sale in Europe. The version of Rio for the inhabitants of Russia was presented in Moscow, August of the same year, but left the assembly line in St. Petersburg. Since 2012, in addition to the sedan, it began to be produced.

In 2013, a sedan and a hatchback were also released, which differed only in body shape and weight. turned out to be 100 kg heavier. For Russian drivers, Rio was distinguished by characteristics specially selected for our roads.

Namely:

• Engine running on AI-92 gasoline.
• Anti-corrosion coating of the bottom of the body.
• Possibility of starting at temperatures down to -35°C.
• A radiator treated with a special protective compound, which is appropriate on winter roads covered with salt.

Features hatchback and sedan 2012:

• Gasoline with an octane rating of 92.
• Volume fuel tank- 43 l.
• Mass of Kia Rio hatchback and sedan - 1565 kg.
• Trunk volume: hatchback - 389 liters, sedan - 500 liters.
• Dimensions: hatchback - length 4120 mm, width 1700 mm, height 1470 mm, sedan - length 4370 mm, width 1700 mm, height 1470 mm.

Both in Russia and in other countries, Kia Rio ranks first in sales. In 2014 he took 3rd place. In just 4 years, the Russians have bought about 300,000 of these cars. New Kia Rio was born in 2015 and was distinguished by the appearance of the interior and body.

Interesting! Kia owners Rio can choose which engine their car can be equipped with: a displacement of 1.4 liters and a power of 107 horsepower, or a displacement of 1.6 liters and a power of 123 horsepower.

Each of the engines has one of the gearboxes in accordance with the configuration: 5 manual transmissions, 4 automatic transmissions, 6 manual transmissions or 6 automatic transmissions. Engines, both one and the second, run on gasoline.

Accordingly, its future characteristics will depend on the choice of the engine. such as acceleration speed, maximum speed and fuel consumption.

Features and specifications for the Kia Rio 1.4 engine

The third generation Rio engine, having a volume of 1.4, is the base one and produces 107 horsepower, 6300 rpm. Which is quite a lot for such a volume, given that the engine works with 92nd gasoline. mechanical box transmission provides acceleration to 100 km / h in 11.5 seconds.

Fuel consumption of a 1.4-liter engine:

• In the city - 7.6 liters.
• On the highway - 4.9 liters.
• In the combined cycle - 5.9 liters.

Dynamics:

• Engine capacity - 1396 cm3.
• Cylinder diameter - 77 mm.
• Piston stroke - 75 mm.

Features and specifications for the Kia Rio 1.6 engine

Kia Rio with this modification of the engine is very popular car in our country. Owners are undoubtedly attracted by the comfort and throttle response of the model. Despite some disadvantages, there are still more advantages, which attracts drivers.

The motor, having such a small volume, has good power indicators of 123 horsepower, which contributes to comfortable driving on the highway outside the city and to feel confident.

One of the drawbacks is the increased noise and harshness of driving. The belt also ensures silence in the cabin. The risk of a chain break is reduced to zero, but just like a belt, it needs to be replaced.

A motor that makes an accompanying noise will give the driver a sign that it is time to change it. There is also a problem that cannot be fixed. In Kia Rio, vibration is often observed when the tachometer needle reaches the average speed, closer to 3,000. This is a factory malfunction of all Kia Rio. There is a resonance that does not lead to a negative outcome.

Kia manufacturers promise a chain life of up to 200,000 kilometers.

Fuel consumption 1.6 liter Kia engine Rio:

• In the city — 8 liters.
• On the highway - 5 liters.
• In the combined cycle - 6.6 liters.

Dynamics:

• Engine capacity - 1591 cm3.
• Cylinder diameter - 77 mm.
• The piston stroke is 85.4 mm.
• The number of cylinders / valves is 4/16.
• The maximum speed is 190 kilometers per hour.

Judging by the reviews of Rio car owners, fuel consumption in the city is much higher, which is another disadvantage. Despite this, most Kia drivers still prefer cars with this particular engine size.

The total resource of the Kia Rio motor

Modern cars consist of a complex system of mechanisms and assemblies, controlled by electronics. You need to understand that the resource of the mechanism is limited and Rio is no exception. New Kia Rio models have a Chinese engine.

The resource of such a Rio motor reaches the mark of 150,000-250,000 kilometers. This is due to the load on the motor and other related factors. Therefore, approaching these marks, owners need to be more careful and attentive to their cars, to carry out maintenance.

Interesting! Basically a resource Kia engine Rio provides for a mileage of 100-150 thousand km.

300 thousand km. - approaching this figure indicates that it is time to repair the sixteen-cylinder engine. The four-cylinder unit installed on the Kia Rio needs more frequent repairs. Kia also has a powerful eight-cylinder engine in its production, the resource of which reaches close to a million kilometers.

If you have purchased a used Kia car, its resource is reduced by several times.

How to extend the life of the engine?

It is worth noting that at correct operation, the motor can work without problems even if the resource is increased. Regular engine lubrication will extend the life of your Kia. Depending on the season, choose the right synthetic oils. Refuel only with high-quality fuel at proven gas stations.

Using cheap gasoline or diesel fuel will quickly disable the engine. Savings later can turn into even greater costs. Carry out preventive maintenance in time and preferably every 5000-7000 kilometers, although Kia officials mention a figure of 15,000.

It is better to pay little by little for the extension of work than to immediately give a large amount. The driving style also affects the engine resource, do not try to squeeze the maximum out of the car. These recommendations will help your unit last a long time and save money.

KIA cars occupy the first positions in the sales ratings of budget models. One of the most popular passenger cars called Rio has been in stable demand for more than one year. One of the reasons for this phenomenon is reliable engines. Many buyers choose a 1.6-liter power unit, to which we decided to dedicate a new article. Today you will learn the resource of this engine, its advantages and disadvantages, as well as the recommendations of experts to extend the life of the unit.

Advantages and disadvantages of the engine

The most famous virtues can be called:

1. Good economic performance. The average fuel consumption of a 1.6-liter Kia Rio is about 6-7 liters in the combined cycle. It's not in "retired" mode, but it's not in racing mode either. This result was achieved by high build quality, as well as well-thought-out parameters of the engine ECU.
2. Magnificent power. Note that according to this indicator, Rio is one of the first lines in its segment. Thanks to this, the car is very dynamic, it copes with overtaking just fine. According to official figures, acceleration from standstill to 100 km / h lasts only 10.3 seconds.
3. High elasticity. The developers were able to best distribute the characteristics between the engine and gearbox. As a result, there is a pleasant feeling of confidence in various situations on the road.

disadvantages engine 1.6 steel:

• Low maintainability. Certain engine components cannot be replaced individually (you have to change as an assembly). Although the repair process itself is greatly facilitated, the disadvantage is the high cost of such procedures. However, this can be said about almost all modern budget cars.
• Engine dimensions. Engine compartment significantly limited, so there are difficulties with access to various components of the engine and its attachments. We have to disassemble some details along the way.
• Aluminum cylinder head. If the engine overheats, the compression ratio as well as compression can significantly deteriorate. At the same time, engines with such a cylinder head are considered more powerful (the difference is 20-30%, compared with engines with a cast-iron cylinder head).

Features and real engine life

One of the very significant advantages of this motor is its reliability and long service life. Since many cars with this unit are already more than 5 years old, there are instances with real mileage exceeding the mark of 300 thousand kilometers. At the same time, the motors work perfectly and do not cause any complaints.

The manufacturer claims that the resource of the Kia Rio 1.6 engine is 200,000 kilometers. But practice has shown that even with not the most accurate and timely maintenance, this unit can last at least twice as long.

How to extend the resource?

Of course, no matter how high the reliability of the power unit is, every motorist would like to avoid its breakdown and maximize the life of the engine. We will look at the main recommendations:

1. Quality fuel. Save money and fill up at trusted gas stations famous brands. Do not use low octane fuel.
2. Timely oil change. The quality of engine lubrication directly affects its resource. Only use oils recommended by the manufacturer.
3. Gentle driving mode. It is not recommended to constantly press on the gas, it is better to drive at medium speeds.

These simple tips will help you significantly increase the resource of the Kia Rio engine.

Summing up

In real conditions, the engine in question has established itself as a very reliable unit. This is one of the best options of those available on the market in this price range. many owners Kia car Rio is advised to buy a car with a 1.6-liter engine.

Today, few people argue that the Korean auto company that produces cars " kia", is very popular and recognizable among motorists. And is it really surprising if it mainly sells budget cars? Although for most Russians the prices are exorbitant. However, Korean models are bought, and this is a fact.

They especially adore Rio". There is nothing strange here either, because it is equipped with, perhaps, the most popular and beloved 1.6 liter engine. Such a volume is not valued in vain, it is the most popular, therefore, as a rule, good reviews are left about it. Such a power unit has excellent and special qualities, but has its own resource And technical specifications, not to do without minuses. This is what we will devote this article to.

Why is the Kia Rio 1.6 liter engine so good

Let's start with a good one. The unit is assembled in such a way that it consumes fuel economically - 6 liters on average. Of course, with reasonable driving and high-quality gasoline filling. It is impossible to disprove the fact that the engine is designed as it should be, and its details are paired without unnecessary gaps. Yes, and it is not made of any material. Plus: experts Kia correctly configured the control unit in this car. Here engine photo:

This motor is said to be the main component of a car that works optimally. Why? He distributes his technical forces in such a way that there is enough power not only for a monotonous trip through city streets, but even for the most virtuoso overtaking. And in general, the model of the “hero of our article” - the Rio motor, is the most dynamic among its “brothers”. Everyone already knows that the machine can accelerate to 100 km for a little more ten seconds. Maybe someone will be outraged, but the company itself claimed it.

Why do some people dislike the 1.6 Kia Rio engine: reviews

When publishing an article about the disadvantages of the Korean unit, we immediately note that although they exist, they are on technical indicators have no effect, much less engine resource. By the way, it is, according to the manufacturer's instructions, 300,000 km. Manufacturers consider such a figure to be the norm, of course. But an adequate and experienced driver will never agree. Here is the first drawback that people often mention in their reviews. In fact, it is often written that there are few shortcomings here, however, paying attention to the opinions of people who have already operated the Rio car, one willy-nilly there will be a desire to write about them.

It is noteworthy that there are motor components that are not completely disassembled. It is clear that this is just a chip that is beneficial for the manufacturer, but it is not easier for drivers. For this reason, the Kia Rio engine can be safely classified as a non-repairable category, because the breakdown will not be repaired by a single part, but by the entire assembly. We are talking, for example, about 2 such important systems as gas distribution and ignition. This is the second minus. And many breakdowns will be ignored altogether and said that they cannot be repaired. These are not our words, they say so Rio owners. Especially often they are sent home when boring of sleeves is required, and they are thin-walled here, and boring is impossible.

By the way, the sector for the engine is limited, and getting something specific is not so easy, sometimes additional analysis is needed. Here is the third item from the list of disadvantages. We can also name a fourth minus: the cylinder block includes an aluminum head, and this can lead to serious damage in case of engine overheating. We are talking about violations of compression and compression ratio.

What conclusion do we make about the Rio engine

Definitely engine "Kia Rio" 1.6 liters deserves attention, as he shows more in action good qualities. It is impossible to categorically note only the minuses, because the unit of any car also has them. It is worth relying on the general opinion about the motor of this model, because it belongs to the segment of modern and improved power devices.
