The real resource of the engine Hyundai Solaris 1.6. Overhaul of the Solaris engine - the complexities and features of the process. How the engine works

To complete a fairly popular car brand, two engines are used, the volume of which is 1.4 and 1.6 liters. The Hyundai Solaris engine is manufactured by the Chinese division of Hyundai. The assembly technology and control over the production process are carried out by Korean engineers, so it is safe to say that the Hyundai Solaris engine is Korean, simply produced and assembled at an external production site.

The Solaris engine is aggregated with a 6-speed manual transmission or a 5-speed automatic transmission. Both motors used to complete the car belong to the Gamma series.

G4FA

The G4FA engine is used on Solaris, Kia Rio and Kia Sid vehicles. This is not surprising, since the Kia car brand belongs to the Hyundai Corporation. The Gamma series is the second generation of modern 1.4-1.6 liter engines, which replaced the Alpha series in 2007.

The 1.4 G4FA engine is an in-line petrol four with an overhead camshaft. The camshaft is driven by a chain drive. Classic L4 SOHC engine layout. Engine capacity is 1399 cubes. Maximum power 100 hp.

The motor delivers a maximum torque of 13.4 Nm at 4000 rpm. The power curve of the engine is almost linear and depends on the rpm. In city driving mode with an average speed of 3000 rpm, the motor produces about 50 hp. The maximum is reached at 6000 rpm.

The torque curve has a constant value mode in the range from 2500 to 3000 rpm and in fact the operating mode is located above the 12 Nm mark throughout the entire operating range.

The factory declared service life is 180,000 km.

G4FC

The G4FC motor is a continuation of the development of the Gamma series. Has the same block as G4FA. The increase in the volume of the combustion chamber was achieved through the use of a different crankshaft and connecting rods, which made it possible to increase the piston stroke, and accordingly the volume. The working volume was increased to 1600 cm3. This led to an increase in power and torque, which became 111 hp. and 15.4Nm, respectively.

The design of the engine has not changed and remained the same L4 SOHC, which implies the use of an 8-valve cylinder head. The drive is also a chain drive that does not require replacement during operation.

Engine resource 180,000 km. This corresponds to the maximum engine life. The limitation is laid down at the design level and is determined by the resource of the cylinder block. Depending on what kind of oil is poured into the engine, the declared resource can be increased or decreased.

Fuel used

Engines of the Gamma series are designed to use fuels with an octane rating of at least 92. Leaded gasoline is not allowed. The capacity of the Solaris fuel tank is 43 liters.

Oil system

Oil for Hyundai Solaris is used on semi-synthetic and synthetic bases. The volume of the oil system is 3.3 liters, but when replacing, 3 liters must be poured into the engine. This is due to the presence of a non-selectable residue that remains on the walls of the highways and the surfaces of the CPG. To determine which oil to fill in the engine, you need to refer to the owner's manual.

What kind of oil to pour according to viscosity indices is influenced by climatic operating conditions, driving mode, operating load. It is almost impossible to formulate an answer to the question - which engine oil is best for use in a particular car.

If the engine often spins up to maximum speed, or the car is used in mountainous areas, which implies frequent prolonged climbs, then it is better to use synthetic motor oils with increased protective characteristics and a viscosity of 0w50 or 5w50.

For normal urban use, the use of synthetics 5 w30 or 10w30 is sufficient. Although, according to its solutions, the engine can operate normally on semi-synthetic oil. The use of mineral lubricants is not permitted.

Engine maintenance

It is recommended to carry out maintenance of power units every 15,000 km of run. The actual operating time before the maintenance of the engine is determined by the operating conditions. When using the car in extremely dusty conditions, heavy operation, implying mountain serpentines, the operation of the car with frequent full loads requires a halving of the service interval.

During standard maintenance, the oil and oil filter, the filter of the incoming air are changed. The chain does not change, since its resource is comparable to the total life of the internal combustion engine. The spark plugs last 30,000 km and the fuel filter must be changed every 60,000 km.

The design of the power unit does not provide for the installation of hydraulic lifters, therefore, every 90,000 km of run, the Hyundai Solaris valves need to be adjusted. Valve adjustment is a rather complicated technological process, therefore it is better to entrust this work to the technicians of a certified service center.

Solaris engine repair

Overhaul of the Solaris engine is not provided. Cast iron sleeves fused into an aluminum block are thin enough and do not require any additional machining. The block boring is not structurally laid.

In addition, the manufacturer does not supply the overhaul sizes of pistons and rings, implying that after the resource is developed, it is necessary to purchase the so-called short-block, i.e. a cylinder block with a crankshaft and mounted CPG elements. As an option for repairing a "disposable" unit, you can use plasma spraying of the material followed by boring to the nominal size.

Such repairs can restore the resource values ​​of the operation of engines. The repairs carried out using this technology have shown a good result, while not only the cylinder walls are restored, but also the crankshaft journals.

Major malfunctions of the Hyundai Gamma series

The most common problem is noise or knocking caused by the circuit. But this malfunction occurs when the engine warms up. If the knock does not go away, then the valves should be adjusted, since incorrectly set gaps are the second reason for knocking.

The Gamma series is very picky about the quality of the supplied air. Dirt on the throttle valve can affect the stable idling of engines. In addition, dirt can affect the stability of the driving speed.

Another malfunction is the whistle. But this sound is not a manifestation of a malfunction of the motor, but signals that the bearing of the tensioner roller is worn out; after replacing the roller, the noise disappears.

Failures often include vibration that appears around the 3000 rpm engine operating mode. Bench tests of the motor show no such vibration. This manifestation is associated with the frequency characteristics of the engine-body system, which enters a resonant state at these speeds of the crankshaft. Increasing or decreasing revs while driving eliminates this annoying feature of the car.

Tuning

Tuning the Hyundai Solaris engine using a different camshaft, changing the intake and exhaust manifolds, turbocharging, as well as making any design changes to the CPG in conditions of simple daily operation is not very common.

An easy way to tune a Hyundai ICE is to change the control unit software. Cancellation of restrictions, according to the ecological class, allows you to add 10-15 hp.

Many motorists are interested in the Hyundai Solaris 1.6 engine resource. After all, the service life of the car directly depends on this indicator. There are 2 types of this indicator. One is called the engine factory life. This value refers to the estimated engine life. Another indicator is the actual resource, and it depends directly on the features of operation. In practice, one owner can drive 200-300 thousand kilometers without any problems, while the other will lose the engine for 50 thousand.

Therefore, the factory resource can only be viewed as a reference material. You can find out the resource of a specific power unit from the technical specifications published by the manufacturer.

Specifications

The resource of the Hyundai Solaris 1.6 engine is one of the indicators of the technical characteristics of this vehicle. In general, the power unit installed on this model is quite reliable. During operation, it practically does not cause any complaints. Engine breakdowns are almost never encountered. With normal maintenance of the power unit, its resource is at least 180,000 kilometers. This indicator is indicated in the vehicle operating book. But, nevertheless, drivers first of all always pay attention to other technical characteristics of the motor:

• Engine volume - 1.591 liters;
• Valves - 16;
• Engine power - 122 HP at 6000 rpm;
• Torque (maximum) - 155 Hxm / 4200 rpm.

The gas distribution system should be considered in particular detail. The mechanism is used here DOHC... The use of such a gas distribution scheme made it possible to make the engine more durable and reliable. The system has a special mechanism of two tensioners that make it impossible for the chain to slip, even when it is strongly stretched. The service life of the chain is calculated for the entire service life of the power unit.

There are also several more positive features that increase the reliability of the engine and its units. The axis of the cylinders is slightly offset relative to the crankshaft, this reduces the load on the piston skirt. The cylinder block is made of hard aluminum alloy. This made it both lightweight and durable.

Engineers abandoned valve hydraulic compensation. Unlike previous engine options found on Hyundai Solaris, this engine will not knock on valves when starting. The lifting of the hinged elements was also a positive feature. In particular, now the generator practically does not suffer even when driving through a rather large puddle.

How to increase the resource of the motor?

Judging by the factory resource, the life of the engine is short. But, with proper care, you can easily extend the life of this unit for a fairly long time without any problems. Even if you do not plan to use the car all this time, proper use will reduce the risk of breakdowns.

The most important job for maintaining the health of the engine in adequate condition is changing the oil. Always use high quality lubricants recommended by the manufacturer. Also take into account the climatic features of operation. The oil must be suitable for the season, otherwise you may get engine problems. It is also important to replace the oil and air filters in a timely manner. This is done simultaneously with the filling of new oil.

Refuel should be done only at proven gas stations. This will guarantee the quality of the fuel, which in turn will extend the life of the engine.

You should not constantly drive the engine at high rpm. Operation of the power unit in modes close to the limit leads to increased wear of parts and premature failure of the motor.

Conclusion... The service life of the power unit of any machine depends on the technical characteristics and features of operation. The service life of the Hyundai Solaris 1.6 engine is relatively small, but with proper use of the car, it can be significantly extended.

No one would argue that most modern cars are programmed to age. And the sudden. If the Solaris engine cannot be repaired, why, who is to blame for this, what to do in this case and what to do to prevent accelerated wear of the motor, let's try to figure it out right now.

Everyone who manufactures cars is interested in selling them as much and as expensive as possible, while at the same time with minimal investment. Hyundai is no exception, especially for the budget Solaris. There are many fairly cheap solutions, inexpensive materials and technologies in the design of a car.... This also applies to the engine.

Official opinion

Officially, Hyundai gives a warranty on the engine without attachments for one hundred thousand miles, or about 180 thousand km, which is about five years of operation. Of course, it is far from the fact that the engine will crumble at the 181st thousand, because we know people who drive Solaris for 250-300 thousand, but there is one factor that no one will be able to avoid.

The Solaris has an engine Gamma G4FA volume 1400 cubic meters in or G4FG-G4FC with volume 1.6 l.

A distinctive feature of motors developed in the early 2000s is the widespread use of aluminum, in particular, the use of this metal for the manufacture of the foundation of any engine - a cylinder block.

Gamma G4FC engine.

On the one hand, aluminum is much lighter than cast iron, which is practically not used for building blocks, it has excellent thermal conductivity. On the other side, aluminum is very ductile and less wear-resistant than cast iron... This is what casts doubt on the possibility of overhaul, which will be relevant for a run under 200 thousand km.

How is an engine overhaul done on Solaris?

The high degree of wear due to the contact of two aluminum parts (piston and cylinder walls) forces engineers to come up with new means to prevent rapid wear.

Often a cast iron liner is pressed into the cylinder block. which wears out much more slowly than aluminum. But there are other methods, for example, on expensive high-performance engines, the cylinder walls are chemically treated with nickel and silicon carbide to obtain a durable wear-resistant surface, or the cylinder mirror is etched and a surface with a high silicon content is obtained.

Impossibility of boring

These are very effective, but expensive techniques, and besides, it is often impossible to bore such a cylinder to the oversize.

Cylinder block liner.

Gamma engine got an aluminum block with thin-walled cast-iron sleeves poured into it. It would seem that this is the very technology that should have made it possible to spend capital over time - to bore a cast-iron sleeve to a repair size, install a repair kit of pistons and rings of larger diameter and wind kilometers further with a repaired block.

Engine problems on Hyundai Solaris

The problem is that the thickness of the liner wall does not allow boring, the liner is almost impossible to get out of the block and replace (it is filled with aluminum at the production stage), and Hyundai did not provide for the possibility of producing repair parts, rings and pistons.

Ideally, each cylinder block with wet liners (surrounded by a water jacket) has liner replacement options, while the Gamma engine has dry liners, that is, tightly fixed in the block.

Repair "in theory"

Already bored cylinders for liners.

Theoretically, replacement of liners in our motors is possible, there are car services that undertake this, it's all about the price. After all, you can buy a new block of cylinders and it will cost an amount comparable to buying a quarter of a used Solaris.

The question arises about the advisability of buying Solaris in the secondary market - in any case, sooner or later the cylinders will wear out and then the capital will again light up the engine.

When is a Solaris engine beyond repair at all?

Diagnosing a dying engine condition is fairly straightforward. This will be indicated by both the mileage on the odometer and quite objective symptoms.:

One-type "disposable" motors

To some extent, the Gamma engine is still disposable, but it is not alone. The engine of the first Skoda Fabia, atmospheric BRZ 1.2-1.4 liters, also uses an aluminum block and thin-walled cast iron sleeves, recent Volkswagen motor EA211 TSI made according to the same technology and manufacturers can be understood - they are not interested in reliability and half a million runs, they need to sell a maximum of equipment at a minimum cost.

Video about the disadvantages of the Hyundai Solaris engine

The owners, however, have no choice but to closely monitor the condition of the engine, use high-quality fuel and oils, spare the engine in the heat and in winter, do not delay adjusting the valves and observe the maintenance schedule. This is the only way to maximize the engine life. Long run for all and smooth roads!

In fact, Hyundai Solaris is an exact copy of the fourth generation Accent sedan for the domestic Korean market. In Russia, the car was presented on September 21, 2010. And its production, and on a full cycle, for our market was organized near St. Petersburg. Cars with a local registration were modified taking into account Russian operating conditions. The first Solaris sedan rolled off the assembly line on January 17, 2011. And a few months later, in May 2011, the assembly of the five-door hatchback began.

For a budget car, the sedan looks very attractive and even respectable due to the combination of complex edges and planes, expressive stiffeners and original optics. However, as our chef will say, design is a purely personal matter. But the people like it. And further. With its modest external dimensions, Solaris looks larger than its closest competitors. But most importantly, the Hyundai subcompact was distinguished by a very favorable price-quality ratio. For the base car with a 1.4-liter gasoline engine then they asked for 379,000 rubles. Solaris 1.6 went from 434,000 rubles. And in full "minced meat" the car cost 634,000 rubles.

Body and electrical equipment

All inclusive

Do not rush to look for money for new front hub bearings, in which play sometimes appears at 20-40 thousand km. It is usually sufficient to tighten the drive shaft nuts - their tightening is weakened by the worn plastic washer between the drive and the hub.

The automatic transmission, according to the assurances of servicemen who are familiar with this unit from other Hyundai and Kia models, has the same resource as the engine. The main thing is to update the branded gear oil in the box after 70 thousand km, which is by no means cheap. But for all its reliability and durability, the "automatic" does not differ in agility and agility. But the gears of a serviceable automatic transmission are shifted softly and smoothly.

Are we buying?

The impression was that the Koreans were in such a hurry to start assembling Solaris that they did not have time to bring it to mind. Indeed, in general, the result is far from the worst budget car in terms of reliability. And the vast majority of owners are happy with it. But minor design mistakes have brought their own fly in the ointment ... However, if you like the car, we advise you to stay on the 1.6-liter version with "automatic" - such a Solaris will create a minimum of problems in further operation.

Hyundai Solaris is a subcompact car, the first generation of which went on sale in 2011. This car, due to its excellent performance and affordable cost, is very popular with buyers. The economical and unpretentious Hyundai Solaris engine had a fairly simple design, which simplified its subsequent repairs.

Two motors of the Gamma series with a working volume of 1.4 and 1.6 liters were installed on the car.

Hyundai Solaris engines have proven to be quite reliable and economical. They were easy to maintain and did not require frequent maintenance. The technical recommendations of the automaker indicated service operations with the engine, and also stipulated which oil to pour into the engine.

Specifications

The base 1.4 liter engine has the following specifications:

The motor is installed on Hyundai Solaris, Hyundai i25 and Hyundai Accent.

The powerful 1.6 liter Hyundai Solaris engine with the following technical characteristics is very popular with buyers:

The engine is installed on Hyundai Solaris and Hyundai i25.

Design features

Both of these power units were distinguished by their reliability and excellent power, which was removed from a small engine.

With a relatively compact size, the engine had a piston stroke of 85 millimeters. The engines were characterized by unpretentious operation, which made it possible to pour inexpensive semi-synthetic engine oil into them.

Of the features of these power units, one can single out:

1. The location of the catalyst in the front of the engine and the timing chain drive. The latter saved the car owner from the need to regularly replace the drive.
2. The timing chain drive, which was used on Hyundai Solaris engines, is a rarity on small motors. This is the prerogative of mainly large-displacement engines from leading car manufacturers.
3. We also note the absence of hydraulic valve clearance compensators, which simplified the design of the motor, and at the same time ensured the smooth and stable operation of the engine.
4. It must be said that a similar engine was installed on the Hyundai Accent. The economical Hyundai Accent engine was distinguished by its ease of maintenance and reliability. This motor does not eat much oil, so these service work can be carried out at intervals of 15 thousand kilometers.
5. Hyundai Solaris engines are equipped with a point fuel injection system, which in turn has increased the power of the power units. It should be noted that the 1.4-liter engine turned out to be high-revving and showed its peak power at 6300 rpm. Whereas at low revs, there was a lack of traction. In the 1.6-liter engine version, this drawback was completely absent. He had an explosive character and a car with this engine showed excellent traction already from 3.5 thousand revolutions per minute.
6. A distinctive feature of the Gamma series power units from their many predecessors is the reverse position of the intake manifold. If the exhaust manifold together with the catalytic converter is located behind the engine as standard, the intake manifold is located at the front. This arrangement allowed to reduce the operating temperature of the engine, which affected the reliability of the unit and oil consumption. Cold air enters the cylinders through the manifold, which improves the combustion performance of the fuel.
7. Another advantage of this arrangement is that it saves space in the engine compartment. All this made it possible to significantly simplify access during repairs to most of the main components of the car.
8. To reduce the friction of the piston on the cylinder wall, its axis was shifted with respect to the crankshaft axis by ten millimeters. All this made the motor work smoother and quieter. The motor does not eat much oil and does not require any serious service. At the same time, there is no vibration and inertia is reduced.
9. The cylinder block is made of lightweight and tough aluminum. In the manufacture of the cylinder block, injection molding technology is used. This made it possible to reduce the weight of the power unit by 11 kilograms, and, at the same time, the power unit retained the strength and rigidity it needed.
10. The motor has no overheating problems, and the Hyundai engine itself has shown itself to be quite reliable and durable. The motor does not require the use of expensive lubricants, so the car owner may not even think about the question: "what kind of oil to pour" into his car, they are all available and are listed in the car's operating instructions.
11. The use of a timing chain drive saved the car owner from the need to regularly replace the belt and engine oil. This increases the ease of maintenance of the motor, and the risk of chain breakage is minimized. It must be said that many car owners are confident that the "eternal" chain does not require any service. However, it is not. Usually, it stretches to a run of 300 thousand kilometers, which requires timing adjustment. It is located in a common block.
12. In later versions of motors of this family, two hydraulic tensioners appeared, which eliminated the need for servicing the chain drive.
13. The gas distribution system is located on the exhaust shaft. The exhaust camshaft rotates according to the engine speed. This ensures high-quality gas-dynamic boost, which is responsible for the thrust and engine power. In particular, the use of such a dynamic valve timing system can improve traction at low and medium engine speeds.
14. The valve drive does not have hydraulic lifters, which made it possible to significantly simplify the design of this mechanism. In this case, it is not required to make any valve adjustments. Regardless of the quality of the fuel used, valve knocking is completely absent.
15. The intake manifold is made with a plastic resonator to reduce air pressure and noise. The absence of intake pulsation has improved the smooth operation of the power unit. The revs are always smooth and even, which in turn endows the small Hyundai Solaris with excellent vehicle dynamics.
16. The exhaust manifold is constructed from stainless steel pipe and has been designed in profile and length to ensure optimum performance of the engine cylinders.
17. Another feature of the Hyundai Solaris power units is the change in the location of the mounted units. The generator is located at the top of the engine, which simplifies the repair of this unit, and protects it from flooding when driving through puddles.
18. The air conditioning compressor has swapped places with the power steering pump. The latter is now located at the rear of the car, and the compressor is located in front of the engine.
19. Hyundai Solaris is one of the first vehicles from the South Korean manufacturer to use an electronic throttle pedal control system. That is, there is no mechanical connection between the motor and the pedal. This allowed the introduction of various electronic systems that are responsible not only for the safety of driving, but also improved the idling of the engine.
20. The operating mode of the generator has changed, which dynamically changes its power depending on the engine speed and the position of the gas pedal.
21. The engine cooling system was also upgraded with a double thermostat. This made it possible not only to increase the efficiency of engine cooling, but also to ensure the fastest possible warming up of the engine after a long parking of the car.

Engine breakdowns and how to fix them

Hyundai Solaris engine tuning

Currently, there are several ways to increase engine power on a Hyundai Solaris car:

• The simplest hardware tuning involves changing the engine control program. The advantage of this option is the ability to obtain a ten percent increase in power, without changing the reliability of the power unit. The cost of such hardware tuning ranges from 5 to 10 thousand rubles. All work takes about 30 minutes, after which the Hyundai Solaris engine receives the necessary increase in power, improving the dynamic performance of the car.
• Chip tuning is also popular, which implies the installation of an additional box with an engine control unit. Such actions are not difficult, which allows the car owner to carry out all the work on his own. He only needs to buy the chip block itself, and connecting it to the engine is not particularly difficult.
• There is the possibility of deep tuning of the engine with a volume of 1.6 liters. In this case, the car owner can get an increase in power of 30%, but this reduces the engine resource. Such engineering tuning involves the complex work of installing a new lightweight crankshaft, cylinder bore and installation of a new machined flywheel. Simultaneously with the change in the mechanical part, the engine control unit is reconfigured. The lambda probe is removed, a zero pressure filter is installed. It is also possible to replace the standard exhaust system with a forward flow.

It must be said that such engineering tuning has not received due popularity today, which can be explained by a number of reasons. First of all, this is the high cost of work, which can be half of the cost of the entire car. You should also take into account the problems with the reliability of the engine, the resource of which after such measures is significantly reduced.

• Some tuning specialists offer the installation of a turbine and balloon equipment with nitrous oxide, however, we would recommend that you refrain from such extreme tuning options. First of all, the car itself is not designed for such a high engine power, so it becomes uncontrollable and simply unsafe. And the resource of the motor with such an intervention is reduced to a minimum. It is not uncommon when, after installing the turbine, the power unit was able to hold out only a couple of thousand kilometers, after which it exploded, which led to the need for expensive car repairs.
