4g64 type engines are quite common. They can be found on cars of different brands, including: Hyundai Sonata, Hyundai Grandeur. Kia Sorento, Brilliance BS6, Dodge
(versions of Ram 50 and Stratus coupe), Chery Tiggo and others. But the most common car brand that is equipped with this engine is Mitsubishi (versions Galant, Chariot, Starion, Tredia, Sapporo, Triton Zinger Magna Eclipse, Outlander, Montero, Space Runner and others). That is why our company offers to repair the Mitsubishi 4g64 engine professionally, quickly, reliably and efficiently! Having worked in this field for many years, our specialists have studied a lot of aspects that are worth paying attention to, so you can be one hundred percent sure of a favorable outcome of the case.
Review and search for problems in the transmission
The Great Wall five-speed manual transmission is not very reliable; the transmission on a Chinese car is characterized by noisy operation and unclear gear shifting. If the manual transmission is noisy at idle, and when the clutch is depressed, the sound disappears, then this means that the input shaft bearing is noisy
. Such a defect can appear on a car quite early, at 30-40 thousand km, but usually the box is repaired after the first hundred thousand kilometers.
An automatic transmission manufactured by Aisin is installed on the Hover paired with a 2-liter diesel engine; there are practically no problems with an automatic transmission. So that the “automatic machine” serves for a long time
, it is necessary to change the transmission fluid on time; it is replaced after approximately 60 thousand km.
Steering and chassis
The suspension on the Chinese SUV is a bit harsh, but the chassis parts last a long time. Shock absorbers are the first to fail; they usually give up after a mileage of 70 thousand km.
The undoubted advantage of a Chinese jeep is that Great Wall spare parts are cheap, their cost cannot even be compared with the prices of a Mercedes or BMW.
The steering rack rarely fails, which cannot be said about the power steering. But if the pump hums
, it is not necessary to change the entire power steering; it is enough to repair the unit by replacing the bearing.
Body parts and paintwork
The crossover's paintwork is not of high quality; paint chips appear on the body quite quickly. The rear wheel arches are primarily susceptible to corrosion.
, and to prevent the body from rusting, anti-corrosion treatment should be carried out.

Brief technical characteristics of 4g64
The 4g64 engine is manufactured by Shenyang Aerospace Mitsubishi Motors Engine Manufacturing Co Ltd Shiga Plant and is known under the Sirius brand. The start of production dates back to 1983 and
continues to this day. Cast iron is used as the starting material.
The engine has an injection power system and four service valves. Moreover, its volume is 2351 cubic centimeters, which allows it to achieve a power of 112 horsepower at 5000 rpm.
A-95 gasoline is used as fuel. At the same time, the toxicity standard for 4g64 corresponds to classes up to Euro-5. All this together assumes fuel consumption per hundred kilometers:
- in the amount of 10.2 liters in the urban cycle;
- in the amount of 7.6 liters in the extra-urban cycle;
- in the amount of 8.8 liters for mixed trips.
- Lowest price for engine overhaul in Moscow
- Diagnostics using modern equipment
- Individual approach to each client
- Guarantees for work performed
- After the repair, you will receive a video report
Some features when using 4g64
The basis for the development of the rather large 4g64 was 4g63. Therefore, this model has some of its technical features. Firstly, there are hydraulic compensators, which eliminates the need to adjust the valves. Secondly, we must not forget about the frequency of replacing the timing belt: it should be done at least every 90 thousand kilometers. Otherwise, the belt may crumble or break, which can lead to more serious problems. Therefore, you should not delay contacting specialists if you notice changes in operation or extraneous sounds.
Preventing a problem from occurring is much easier than solving it later.
How to get to us
Interior
How to correctly format the technical characteristics of a product. Specifications are
Plastic surgery on the “face” of the Great Wall Hover never made it to the interior – the SUV’s interior almost completely copies the H3 model. Except that now the “fifth” Hover has a leather interior, electric front seats and a parking camera for viewing everything that is happening behind. The Chinese decided to get rid of dubious navigation. This is a completely reasonable move, given the inability to compete with mounted navigators. The decision to make a new car that can be classified as a luxury car, but at the same time to remain practical and convenient, is understandable; Asians want to reach as many potential customers as possible. The salon is equipped with comfortable ergonomic seats. The greatest comfort is possible only when there are no more than four people in the cabin. High-quality genuine leather was used as a finishing material; the steering wheel and many other elements were also decorated with it.
The designers of the Great Wall Hover H5 relied on a wraparound design, so the control panel blends smoothly with the lines of the wing. And the contrasting connection of the interior trim with the drop-down instrument panel makes the elements visible and the driver will not have any difficulties while driving. The seats in the cabin can be folded in three different ways to provide maximum comfort for the occupants. The driver's seat can be adjusted in six different positions. By the way, what is not typical for Chinese cars is heated seats, which is present in this SUV. The location of the on-board computer is very convenient; it will be very convenient to control the cabin acoustics and media system. While driving long distances, you may feel tired, since the front seats are made in a sporty manner, but do not meet all the criteria for comfort. It is worth noting that the headrests in the car are adjustable and even a tall person will be comfortable in the back seat.
The fifth model of the SUV is equipped with a spacious trunk, which in standard mode can accommodate 810 liters of cargo, and if the rear backrests are folded, then up to 2074 liters. There are two round diffusers on the center console, and directly below them there is a large monitor on which you can monitor the technical condition of the vehicle and control the multimedia system. Which by the way supports AUX, USB, Bluetooth and all popular music formats. The rear of the car is equipped with a camera, so when driving backwards an image will appear on the same monitor. The climate control is divided into two zones and equipped with sensors. Therefore, do not be surprised if the system detects a decrease in the temperature outside and automatically turns on the heating in the cabin. Having given the interior solidity, the Chinese still forgot to attach hooks for clothes, change the manual transmission poker and do at least something with the chaotic combination of plastic of different textures. Well, okay, given the origin of the car, everything can be forgiven for it.
Engine tuning 4g63
Technical characteristics of the Toyota Land Cruiser Prado Toyota Land Cruiser Prado 2.7 AT 163 hp 4WD
Car enthusiasts tune the engine installed on Mitsubishi Galant cars and other models. Thus, it is possible to improve the technical characteristics of the power plant. To upgrade the 4G63S4T, perform the following series of actions:
- Replace the camshafts with products with a different phase. Replacing camshafts will make it easier to supply the fuel mixture to the working chamber and remove exhaust gases;
- Eliminate irregularities in the intake tract. This is necessary for the smooth supply of air mass into the combustion chamber;
- Flash the electronic engine control unit.
Firmware of the electronic control unit will allow you to change the timing of fuel injection. This will make it possible to increase the maximum power and dynamic performance of the engine. To reprogram the electronic control unit, specialized equipment is required.
From the above it follows that the Mitsubishi 4g63 engine is a high-quality power unit. The motor is distinguished by high technical performance and unpretentiousness to operating conditions. The engine was installed on various Mitsubishi cars. During production, several modifications were released.
Tuning the Mitsubishi 4G64 engine
DOHC+Camshafts
To increase the power of the 4G64 without a turbine, we will need to remove the single-shaft cylinder head and buy a head from the 4th generation Hyundai Sonata (G4JS engine) along with the intake manifold, modify it, remove roughness, and combine the channels. In addition, we need to purchase an Evo throttle body, a cold intake, ARP studs, forged pistons for a higher compression ratio (~11-11.5, for example Wiseco), Eagle connecting rods, remove the balancer shafts, buy 272/272 camshafts with split gears and reinforced We take springs, a fuel rail from Galant, injectors with a capacity of 440-450 cc, a Walbro 255 pump, a 4-2-1 exhaust manifold (4-1 is possible), an exhaust on a 2.5″ pipe, additional small things and re-flashing. With all these components, the 4G64 engine's power will rise to 200+ hp.
4G64T
To further increase the power, the modifications described above will not be enough and the engine must be inflated. The easiest way is to buy a cylinder head from Lancer Evolution, with everything attached, with a turbine, intercooler, fan, manifold, exhaust, which needs to be modified to fit the desired car. In addition, the oil supply to the turbine will require improvements, at the same time you will need ARP studs, 272 turbo camshafts with split gears and reinforced valve springs, a forged piston (compression ratio ~8.5-9), Eagle connecting rods, you need to remove the balancer shafts, buy injectors from Evo 560 cc or more efficient, Walbro 255 pump. After tuning, we get 400+ hp. For increased torque of the 4G64, it is necessary to replace the crankshaft with an 88 mm from Evo or a lightweight one, 156 mm connecting rods (titanium for high power) and bore the cylinders to 87 mm, in total this will give 2.1 liters and a very high revving engine. At this low end you can put a Garrett GT42 with everything that comes with it and drive quite well... in a straight line.

out of curiosity, they would read what is written on the valve cover - MIVEC (phases and valve lift heights change (Mitsubishi Innovative Valve timing Electronic Control system)) - they began to use it in the late 90s, and it is also written that the turbo .. this engine has about 260 -280 mares in stock .. and the engine in the photo is hardly older than 2000 ..

dimagalant What is this 4G63 you have, what is 109 hp. ? This engine was installed on old Galantes and Evos (starting with the 3rd, I think) and is still installed on the IX, as well as on Clips of the first two generations. Depending on the degree of boost, its power varied from ~140 to ~150 hp. in a naturally aspirated version.

I forgot about the eight-valve 4G63, I’ve just never seen one like that... I saw the ’88 Galant. There was a 4G63 Turb, about 210 hp, everything except the intake/exhaust was stock, they said it ran no worse than the current Imprez WRX.

This 2-liter 4-cylinder, 16-valve miracle engine of Japanese engineering with a turbocharger and intercooler of charge air of Japanese engineering was and is installed on the Lancer Evolution IX. At any point in the external speed characteristics, the Mitsubishi 4G63T MIVEC turbo engine produces “hurricane” torque. To improve dynamics at low and medium speeds, Mitsubishi engineers equipped the engine with a new proprietary system of electronic control of valve timing and valve lift MIVEC, and also optimized the operation of the turbocharger. The result is obvious: driving characteristics have improved in all modes, and especially in the proprietary Lancer Evolution range - from 3000 to 5000 rpm. This means that on the road, the Evolution takes off from a standstill and accelerates powerfully when overtaking (acceleration to 100 km/h takes just 5.7 seconds).

on the 63rd turbo engine they were installed from 2005 to 2007 and that’s it, later motors with the index B came in. On the Galanta, in principle, such engines were not installed as stock.. with MIVEK, motors were installed since 1992 on Lancers and Mirages with the index 4G92.. ( if we talk about inline fours)

The K9K858 diesel engine, which became the basis for the restyled Dusters, should wear out in the same way as the 884 series engines. Over time, the power will drop in any case. And also, the elasticity of the engine will gradually disappear. It, as stated here, is the main advantage of all Renault diesels. Just in case, here is a list of them:
- K9K796, K9K830 – 86 hp.
- K9K884, K9K892 – 90 hp.
- K9K896 (4x2 only) – 107 hp.
- K9K856 (4x2 only) – 109 hp.
- K9K858 (for 4x4) – 109 hp.
- K9K898 (for 4x4) – 110 hp.
The Renault catalog contains many more options - for example, K9K728 or 724, but they are not related to the Duster family. Renault installs all the best in crossovers - believe me, in reality this is so.
The main character of the last chapter is the K9K858 motor
Exterior
The appearance of the Hover H5 has not changed much, with the exception of the front part. Now the Chinese SUV is even more similar to the Mazda CX-7 thanks to a new bumper, modern lighting technology and smooth lines. As for the dimensions, the Great Wall Hover H5 test shows that the car has grown in length to 464.9 cm and in width to 181 cm. But it has lost height compared to its brother H3 - 174.5 cm versus 180 cm. Second generation SUVs from the famous manufacturer Great Wall are also all-wheel drive. The design of the car has undergone a number of changes. This especially affected the radiator grille; it became completely unique and unlike other cars. A clear benefit to the design of the car was that the engineers decided to follow their own path of development, and not copy someone else's style.
During the production process, only the highest quality metal with a high margin of safety was used for the body, which also gives the car solidity. According to a representative of the Great Wall company, the plant has installed the latest equipment that performs laser welding of the frame. In addition to the radiator grille, significant changes affected the optics. The pronounced lines of the front and rear headlights give the SUV a sensual aggression that just begs to be seen. The car's bumper is decorated with stampings, which is typical for premium class cars. Massive fenders and seventeenth-radius wheels give the car additional uniqueness and originality.
The headlights are convex in shape and divided into unique sectors with the latest optics. On the radiator grille, the designers placed the brand's signature stripes in the style of bird wings and the manufacturer's logo. Turn signal indicators are installed on the side rear view mirrors. The rear bumper has a special threshold, which is useful during loading and unloading operations. What is surprising is that the company produces great wall hover h5 in various colors.

Has anyone removed the 4G64 cylinder head? Are there any nuances?
Grandmother_Axe » May 29, 2020, 1:37 pm
Car P2 96.
dorest, engine 2.4 4G64 The gist is this: from the junction of the cylinder head with the engine, oil gushes from the side of the box, directly onto the box. It would be necessary to remove the cylinder head and polish it. Moreover, I have problems with the stove pipes there, I will also change them, and it’s easier to get to them when the cylinder head is removed. Well, I took the timing belt replacement kit and will change it just in case. In short, I will fix it. The question is, who filmed the thread? Are there any details about replacement? I'm especially concerned about the distributor. To replace it, I bought: - cylinder head gasket - intake manifold gasket - timing belt, tensioner and damper - camshaft and crankshaft seals - rings for the injectors (I’ll also remove and clean them) - oil and filter Maybe I forgot something? Maybe something else needs to be changed? And one more question, or rather a request for help. 1. Where in Vladivostok they grind the cylinder head, so that it is high quality, on a machine and with a grinding stone, and not with an ordinary shit milling machine. 2. Is there a place to download the manual? I'm interested in the tightening torque of the studs and the clearance in the valves. 3. Let someone use a torque wrench, a pulley tensioner wrench, and valve adjustment gauges. I don’t have such tools, only a small set. If one of the clubbers agrees to help and provides an equipped room for repairs, that would be great! Thanks to everyone who answers.

How does the torque graph change with engine wear on Renault Duster?
All Duster diesel engines are valued for the fact that maximum traction is achieved at low speeds. We are talking about numbers less than 2000 rpm, and this is the main “plus”.
But over time, that is, with increasing odometer readings, the maximum point shifts to the right.
Torque and power, “90 hp” version, mileage
From the graph you can understand what will happen to the K9K engine if it “runs” about 70 thousand km.
Features that were not present with “zero” mileage:
- The greatest traction force became equal to 204 N*m. Maybe the stand is “lying” (inflating the values). We will assume that the numbers remain the same - 200 N*m.
- Rated power decreased to 88 hp. But taking into account the “overstatement” of 2%, the power should be considered equal to 86.4 hp.
What exactly will be observed as the mileage increases?
At a mileage of a third or half of its life cycle, the engine begins to “age”:
- Power decreases: “at nominal” it should be 90, but there will be 86-87 “power”;
- We can talk about the loss of “elasticity”: traction is lost “at the bottom”, but not in the area of 2000-2750 rpm;
- The maximum torque value does not depend on wear in any way.

The 4G63T is a 1997 cm3 four-cylinder in-line petrol engine with turbocharging and DOHC valve timing. Maximum power 185-280 hp. With. at 6500 rpm, maximum torque 382 N*m at 3500 rpm. It has a cast iron block and forged steel connecting rods. installed on Mitsubishi Lancer Evolution from 4th to 9th generation inclusive. The victories of Mitsubishi cars in world rallies are numerous and they have received a huge number of awards. So racer Tommi Mäkinen was invincible at the wheel of this car from 1996 to 1999. His team won the 1998 World Manufacturers' Championship.
Engine design 4g63
Thanks to its design, the Mitsubishi 4g63 engine is a reliable unit that works well regardless of operating conditions. With the help of modernization, you can improve the technical characteristics of the motor several times.
Pistons and crankshaft
The Mitsubishi 4g63 engine has a crankshaft with five main and four connecting rod journals.
For stable engine operation, the crankshaft is equipped with counterweights. There are holes in the necks. They are necessary to supply lubricant to the plain bearings.
The transmission of force from the piston to the crankshaft is carried out using a connecting rod. The engine is equipped with forged connecting rods. A pin is installed on the upper part of the part; it is necessary for the hinge connection of the connecting rod with the piston. A sliding bearing is installed at the bottom of the product. The bearing is secured with a cover.
The engine pistons have grooves for installing compression and oil rings. Compression rings are necessary to prevent leakage of the working mixture from the combustion chamber into the crankcase. Oil scraper rings prevent lubricant from entering the working mixture.
The bottom of the piston is equipped with specialized openings. They are necessary to maintain the integrity of the valve mechanism in the event of a timing belt break. If the timing belt breaks, the open valves will fall into the openings.
Gas distribution mechanism
Depending on the modification, the Mitsubishi engine is equipped with a single-shaft or double-shaft gas distribution mechanism. Cam-type camshafts are driven by a pulley mounted on the crankshaft. A toothed belt is used for drive. The belt tension is automatic. A specialized tensioner is used.
When the camshaft rotates, the cam moves relative to the axis. The moving part of the shaft acts on the valve stem, thereby opening it. In the opposite direction, the valve moves under the action of a spring.
To prevent lubricant from entering the working mixture, the valve mechanism is equipped with oil protective caps.
Cooling system
Between the liners and the walls of the cylinder block there is a cooling jacket. At the top of the block the cooling jacket is open. It communicates with the channels located in the head. This design avoids overheating of the cylinder head regardless of the load.
Forced circulation of liquid in the cooling system is carried out by a pump. It is belt driven by a pulley mounted on the crankshaft. Under the action of the centrifugal force of the pump, the working fluid moves from the cooling jacket to the upper radiator tank. In the radiator, the liquid is cooled by passing through thin channels. From the lower reservoir, the liquid enters the jacket of the power unit.
Cooling of the liquid as it passes through the radiator channels is carried out by air. Forced movement of the air mass through the radiator honeycombs is carried out by an electrically driven fan.
Lubrication system
The Mitsubishi 4g 63 engine has a mixed lubrication system. The rotating parts of the crank mechanism are lubricated with oil sold under pressure. The oil pressure in the system is created by a gear-type pump.
To lubricate the plain bearings, there are holes in the crankshaft journals. When the power plant is operating, oil under pressure is supplied through the holes to the plain bearings. This design allows the bearings to be effectively lubricated regardless of the degree of load on the power unit.
Parts of the gas distribution mechanism and other parts not subject to high loads are lubricated by spraying oil. After splashing, the lubricant flows through the channels into the oil pan.
Design Features
The 4G69 engine was designed based on an earlier version of the same 4G64 series. The main design nuances were:
- long piston stroke of 100 mm, which required lightening the connecting rods from 623 to 530 g, the crankshaft from 15.8 to 14.9 kg and the pistons from 354 to 278 g;
- cylinder volumes increased to 2.4 liters, made of cast iron liners inside a block made of the same material;
- reducing the block height to 284 mm while simultaneously increasing the cylinder diameter to 87 mm;
- single-shaft SOHC 16V cylinder head with integrated MIVEC system;
- increase in valve size to 30.5 mm and 34 mm (intake, exhaust, respectively);
- timing drive by a narrow toothed belt with a service life of about 90,000 km;
- the presence of one balancing shaft with a belt drive;
- EGR exhaust recirculation system, which increases the European protocol for the environmental friendliness of the engine, but reduces the power and resource of the intake tract.

An important feature of the atmospheric version of 4G69 was the modified attachments. First, management changed the design of the intake tract, then the exhaust manifold had to be modernized. This power drive does not have a turbo version, but there is potential for inflatable and mechanical tuning with your own hands.
The MIVEC system was designed to increase engine power by 13%:
- 8% due to controlled valve lift;
- 2.5% due to accelerated supply of the fuel mixture;
- 1.5% due to reduced resistance in the exhaust valves;
- 1% due to a slight increase in the volume of the combustion chambers.
As a result of testing, additional bonuses were revealed - stable operation of the internal combustion engine, increased environmental standards and fuel economy. On the other hand, the fluid coupling is sensitive to the quality of the oil.
A single-shaft SOHC timing system for controlling 16 valves is not the simplest technical solution. This also reduces the service life and maintainability of the motor. Every 30 - 40 thousand kilometers the valve thermal clearances have to be adjusted.
ShPG 4G69
In the 4G6 series (Sirius), this power drive is the only one equipped with a phase control system. There are no official modifications to this engine.
