The first instances of the power unit were developed in 1975 for installation on Mitsubishi Galant. They were called G62B and calculated on a working volume reaching 1850 cubic centimeters.

The next stage of evolution was the G63B engine, which was distinguished from the predecessor greater tank, diametrical sizes of cylinders and casting on the block.

ATTENTION! Found a completely simple way to reduce fuel consumption! Do not believe? Auto mechanic with 15 years old also did not believe, until he tried. And now it saves 35,000 rubles per year in gasoline!

In 1980, the design was complemented by a mono-engine system equipped with turbocharging and had 12 valves. This model was developed for installation on the Lancer EX2000 and Galant Lambda. In 1984, the power unit of the injection variety, equipped with 8-shlnami, appeared. At about this time, a motor under the name 4G64 was developed, which had a different diameter of cylinders, a piston move and a higher location of the unit. Engine mounted on different types vehicles depending on the modification.

In the future, he has undergone significant changes. The designers conducted a deep modification of the power unit, the DOHC variants appeared, the power characteristics have increased significantly and the damage applied to environment. In 1986, a modification appeared with the 16th valves. She had a reduced dimension, but the capacity exceeded its predecessors.

New changes in the power unit were subjected to 1993, when the flywheel began to be attached to the crankshaft on 7 bolts.

In parallel with the novelty, the old version with the 6th bolts continued to be mounted on various vehicles. In 1998, the engine was used as a basis for creating a more powerful modification designed for a working volume reaching 2.4 liters.

It was made to install on Hyundai Sonata. The versions of the power unit, calculated on 8 valves, ceased to produce when the ecological standards tighten occurred and the effect of globalization occurred. The engines have become necessary for 7 years, and not at 15.

The last motor of a similar variety, equipped with a carburetor, lasted in production much longer due to low cost and high reliability. It was installed on commercial cars until 1998. In 1997, the Motor version of 6 bolts, equipped with turbocharging injector, was finally removed from mass production. In 2003, a modification of a power unit, having 7 bolts and the MIVEC bolt appeared.

The MITSUBISHI 4G64 engine was developed on the basis of 4G63 and had a working volume reaching 2.4 liters.

Initially, he thought as replacing the outdated 4G54, which was removed from production in 1983.

For its history, the power unit survived a large number of modifications and showed itself as a reliable and durable engine with good power characteristics.

Specifications

Mitsubishi 4G64 engine is a rather popular motor. In its block is mounted crankshaftwhich has a course of 100 mm. Compared to the predecessor, the diameter of the cylinders was boring and reached 86.5 mm. Balancing shafts were not subject to change, and the compression height of the pistons is leveling 35 mm at the length of the connecting rods reaching 150 mm.

The head of the cylinder block is made of aluminum alloy and includes 8 valves.

It is worth noting that during the mass production it was revealed that this is not enough, the number of valves increased to 16. On both versions of the power unit, a hydraulic compensator is mounted, excluding adjustment. The design includes a timing belt, requiring replacement every 90,000 km. It is necessary to carefully follow it, because the opening leads to education bent valves And excess spending. Like any power unit, the engine Mitsubishi 4G64 has a number distinctive features, namely:

1. Operating volume reaching 2.4 liters. This is equivalent to 2351 cubic centimeters.
2. Injector injection injection variety.
3. Power that may vary from 112 to 150 liters. from.
4. Fixed number of cylinders, equal to 4, on the engine of this brand.
5. The number of valves that can vary from 8 to 16, depending on the modification.
6. Fuel consumption consisting of 8.8 liters per 100 km. This value remains true if the power unit works in the offset mode.
7. Resource exceeding 400,000 km.

The Mitsubishi 4G64 engine is quite powerful and reliable. Uninterrupted work can be ensured if used quality details and consumables. The motorist stands responsibly approach the choice of fuel, since poor fuel can lead to premature troubleshooting. Full diagnosis I. maintenance It is necessary to exercise every 8000 km.

Many motorists have difficulties related to the search for the engine number. Often they do not know where it is located. This causes delays when the driver deals with the traffic police officers. As a rule, traffic cops are aware of the location of the digit set, but if it is not so, then the owner of the car should be aware that it is necessary to search from the left side. The number is under the collector. It is very difficult to see it, so a mirror is often used.

Moreover, the figures are often impossible to disassemble because of the dirt accumulating on the motor. In such a situation, you will have to clean with undergraduate means. With a large probability, you will have to remove some components for this.

How reliable the power unit

Motor has 16 valves and works on gasoline. Fuel injection is performed by e-device. The design is capable of providing high power and pretty stable work. The engine can function at elevated time for a long time and spend a small amount of fuel.

The average motor resource can be significantly increased if the car enthusiast refers to it carefully.

Extend the life of the engine will allow the use of high-quality oil and good gasoline, Regular diagnostics and maintenance. The first problems may arise in several years of continuous operation, but their operational elimination will avoid more serious problems and increase the service life. For the power unit, it is characteristic:

1. The presence of a problem related to balancing shafts. Problems often arise due to insufficient lubrication. Significantly increases the risk of the wedge of the parts and the sudden break of the belt on the shafts. A similar phenomenon leads to a more serious problem, such as the failure of the timing belt. Avoid breakdowns is quite simple. It is enough to acquire and pour into the engine only high-quality oil, monitor the state and regularly inspect the beltenis, if necessary, producing a replacement.
2. Vibration, which has a property to enhance and lead to serious problems, if not paying attention to it. Often it arises due to malfunctions in the cushion of the motor. At the first signs of vibration, the source will find the source and replace the faulty components.
3. Floating turns. They appear quite rarely, but require adoption of immediate measures. It is not easy to find the cause, since the source of the problem may be nozzles, temperature sensors, closed throttle or regulator idle move. You can avoid troubleshooting if you can perform regular check and clean the components of the power unit from the accumulated dirt.
4. Fast failure of hydraulic compensators. The problem appears with long-term use of low quality oil. When a similar breakdown is detected, it should be replaced faulty details And in the future, only high-quality lubricant material is used.

The power unit is characterized by a small number of troubleshooting. Even with inept operation and the complete absence of timely diagnostics, the motor resource will be more than 400,000 km. Thanks to such a feature, it has deserved popularity among drivers who value high reliability in combination with power. The listed problems are easily eliminated under the conditions of a personal garage in the presence of appropriate skills.

Maintainability and tuning

When using the Mitsubishi 4G64 engine, the motorist should explore the main problems described above. Their elimination can be engaged, without having specialized equipment on the hands. Any of the listed problems is eliminated in a personal garage without excess costs. Moreover, the reliable design makes it possible to produce tuning with your own hands. For this, it is not necessary to contact the service station if there are appropriate skills and experience.

Improvements are often produced in order to increase power. The motor is well served such a modification, which practically does not affect the resource with skillful intervention.

Most often, in order to increase power, changes in the turbine, and also replace air filter and set the so-called nulevik. In order to increase the power characteristics, the standard intake system Replaced with a straight-in inlet with a pipe that does not have any essence along the entire length.

Changes are subjected to pistons in the cylinders. They are doing more reliable so that they can cope with large loads. Self car enthusiasts prefer to acquire new turbines and subjected to the CBC modification. Such measures make it possible to increase the power of the force aggregate several times. Improvement allows you to increase the number horse power up to 1000. Such motors are not rare even today.

However, motorists who have achieved such a result know that vehicle With such characteristics should be equipped with a reinforced transmission. Otherwise, successful modification can turn into a number of problems.

What oil pouring

How repeatedly mentioned above proper selection Lubricant material will allow to extend the life of the motor and ensure stable operation. Mitsubishi 4G64 engine can be filled with marking oil:

1. 15W-50, which is a semi-synthetic lubricant material. It is well suited for the engine, working in hard conditions and on high revs. The number of distinctive features includes a high index, good indicators thermal stability and the presence of a complex of special additives. Oil effectively protects the parts of the motor from the formation of corrosion, foam and premature wear.
2. 10W-60, ideally suitable for a power unit possessing good operational characteristics. The lubricant material has a high viscosity that reduces the formation of Nagara. The leak is excluded due to the presence of special additives.

3. 10W-50, which includes additives in the form of long molecules, as well as mineral and synthetic components. Lubricating material refers to the all-season variety and is able to effectively protect the parts of the motor from wear during dry friction, carry out cooling of the components during operation, effectively remove the waste of combustion products, eliminate the formation of slag and oxidation, extend the operational period of the power unit, and reduce oil and fuel . Moreover, lubricating material having such marking does not need to be changed often, which contributes to savings. It is able to effectively perform its functions in a large temperature range and stabilize the operation of the engine in extreme conditions.
4. 10W-40, which is the most common. The oil is universally and has high technical characteristics. It is semi-synthetic and used both in summer and in winter with the same efficiency. The use of such a variety in regions with a temperate climate is a faithful solution. But the lubricant material freezes at 20 degrees. If the car does not turn out to be in such conditions, then quick Start The power unit is guaranteed. The top-temperature threshold of the described oil reaches +35 degrees. If you cross it, then the semi-synthetic will lose part of its properties and cannot effectively protect the motor from corrosion and premature wear.
5. 10W-30. It represents mineral oil and produced from natural components. Paraffin is used as the basis. The manufacturing process is accompanied by the use of innovative technologies. Special additives make it possible to use it all year round. If you pour it into the engine, it will be possible to significantly reduce the level of toxicity. exhaust gases, prevent rust formation, Nagara in friction assemblies and slow down the oxidative processes. The oil is ideal for working at elevated temperature mode.
6. 5W-50, which equally effectively performs its functions in new motors and having a large mileage. The composition includes unique patented additives, providing minimal clusters harmful substances, as well as the formation of soot and soot. Thanks to similar characteristics, the lubricant preserves beneficial features long period.

Each type of oil, described above, is well suited for use in the Mitsubishi 4G64 engine, but the motorist needs to be chosen, based on the conditions in which the motor is operated most of the time. This will allow you to optimize the work.

Mitsubishi 4G64 / 4G69 Engine Hydrocomatcher Check

Immediately after starting the engine or during the engine operation, if a foreign (rattling) sound is heard, which comes from the hydrocompensator, fuel it and follow the check.

Check out motor oil And the frace or replace the oil if necessary.

If the amount of oil is insufficient, the air falls through the mesh filter of the oil pump in the lubrication system channel.

If the amount of oil is greater than the norm, then the oil is overly shaken when rotating crankshaftAnd a large amount of air gets into the oil.

Air and oil will not be easily separated if the oil is old (lost its properties - degenerated) and the amount of air in oil will increase.

If the air gets into the chamber high pressure The hydrocompensator, then it will be compressed inside it during the opening of the valve, and, as a result of this, the plunger of the hydraulic components "will seek", and an increased noise of valves will be heard.

This is the same effect as if the clearance in the valve drive is not adjusted (too much clearance).

The work of Mitsubishi 4G69 / 4G64 hydrocompensator will be normal when the air falling into it will be deleted.

To remove air from the hydrocompensator, run the engine, and gently press the accelerator pedal several times (10 times or less).

If the increased noise has disappeared, the air was removed from the high pressure chamber, and the work of the hydrocompensator returned to normal.

First, gradually increase the engine speed of the crankshaft from the idle speed of up to 3000 rpm (for 30 seconds), and then gradually reduce the rotational speed of the engine crankshaft back to the idle speed (for 30 seconds).

If the car is parked on a slope for a long time, then, sometimes, the amount of oil in the hydrocommovensector can decrease, and the air will fall into the high pressure chamber when the Mitsubishi 4G64 GDI engine is started.

If the car is parked for a long time, the oil will come out of the lubrication system.

Therefore, a small period of time is required to supply the oil to the hydrocompensor (the air can sometimes get into the high pressure chamber).

If the increased noise has not disappeared, then check the hydroke-compatherers in accordance with the following procedure.

Muffle the engine.

Install the first cylinder piston in the compression tact.

Press the valves on the rocker and check if the valve rocker moves or not.

Slowly turn the crankshaft 360 ° clockwise.

Check the Mitsubishi 4G64 / 4G69 engine valves rocker.

If the valve rocker moves down after pressing, then replace the hydrocompanator.

When replacing the hydrocompanator, remove the air from all hydrocompensators, and then follow the initial procedures.

In addition, if the valve is pressed on the rocker, there is an excessive resistance, and the rocker does not fall down, then the hydrocompensator is in order and cause of a malfunction in another.

Mitsubishi 4G64 / 4G69 Engine Invitation Angle Angle Angle Angle

Insert the clips to the 1-pin connector between the chain of the primary winding of the ignition coil and the obstigious resistor.

The connector should not be disconnected.

Insert the clip along the output from the opposite side of the connector latch.

Connect the tachometer test wire to remove the voltage in the primary winding circuit of the ignition coil to the clip installed in the connector.

Do not use MUT or MUT-II. If Mut or Mut-II is connected to the diagnostic connector, the device will show the current ignition advance angle, and not the base angle.

Start the Mitsubishi 4G69 / 4G64 engine and let him work at idle.

Check that idle rotational speed corresponds to the nominal value. Nominal value: 750 ± 100 rpm.

Turn off the "ignition" (key position "OFF").

Install a strobe.

Remove the waterproof plug from the ignition advance adjustment adjustment connector (brown).

Using the wire with the connector, connect the output of the adjustment connector of the base angle to the "mass".

The connection of this slot with the "mass" translates the engine Mitsubishi 4G64 / 4G69 to the mode of operation with the base angle of the ignition timing.

Run the engine and let it work at idle.

Check the magnitude of the base angle of the ignition advance, which should be within the specified limits. Nominal value: 5 ° to VMT ± 2 °

If the basic ignition advance angle does not correspond to the nominal value, then adjust the ignition advance angle to the rotation of the distributor housing.

The ignition advance angle will decrease if the ignition distributor is turned clockwise, and will increase if the ignition distributor is rotated counterclockwise.

After adjusting the ignition advance angle, gently tighten the mount nut so as not to move the ignition distributor.

Move the engine, disconnect the wire from the ignition alert adjustment connector (brown) and install the waterproof plug into the connector.

Run the Mitsubishi 4G64 / 4G69 engine and verify that the ignition advance angle corresponds to the nominal value.
