Popular diesel engines in Belarus and their “diseases”. Mitsubishi diesels

Engine history

The engine division of the Japanese automaker Mitsubishi has been developing the 4d56 engine for ten years. As a result, they produced a fairly powerful power unit that is capable of simultaneously quickly accelerating such a difficult car as the Mitsubishi Pajero Sport and overcoming off-road conditions.

Mitsubishi 4d56 (pictured in section) debuted back in 1986 on the first generation Pajero. It is the successor to the 2.4-liter 4D55 engine.

The short block of this engine is made of cast iron alloy, which includes an in-line arrangement of four cylinders. The cylinder diameter has been slightly increased compared to its predecessor 4D55 and is 91.1 mm. The block is equipped with a forged crankshaft with two balancing shafts and an increased piston stroke. The length of the connecting rods and the compression height of the pistons have also been increased and are 158 and 48.7 mm respectively. As a result of all the changes, the manufacturer managed to achieve an increased engine displacement of 2.5 liters.

On top of the block is a cylinder head (cylinder head), which is made of aluminum alloy and includes vortex combustion chambers. The engine gas distribution mechanism (GRM) is equipped with one camshaft, that is, two valves per cylinder (one intake and one exhaust). As expected, the diameter of the intake valves is slightly larger than that of the exhaust valves (40 and 34 mm, respectively), and the valve stem is 8 mm thick.

Important! Since the 4D56 engine was produced quite a long time ago, the gas distribution system does not feature any innovative solutions. Therefore, it is recommended to adjust the valves (rockers) for this engine every 15 thousand kilometers (the clearances of the intake and exhaust valves are 0.15 mm on a cold engine). In addition, the timing drive does not include a chain, but a belt, which indicates its replacement every 90 thousand kilometers. If this is neglected, the risk of belt breakage increases, which will lead to deformation of the rockers!

The Mitsubishi 4d56 engine has analogues in the engine model line from the Korean automaker Hyundai. The very first variations of this engine were naturally aspirated and did not differ in any outstanding dynamic or traction performance: the power was 74 hp and the torque was 142 N*m. The Korean company equipped their D4BA and D4BX cars with them.

After this, the production of a turbocharged modification of the 4d56 diesel engine began, where the MHI TD04-09B was used as a turbocharger. This unit gave the power plant new life, which was reflected in an increase in power and torque (90 hp and 197 Nm, respectively). The Korean analogue of this engine was called D4BF and was installed on Hyundai Galloper and Grace.

The 4d56 engines that powered the second generation Mitsubishi Pajero were equipped with a more efficient TD04-11G turbine. The next modification was the addition of an intercooler, as well as an increase in the main technical indicators of the engine: power to 104 hp, and torque to 240 N*m. This time the power plant had the Hyundai D4BH index.

The release of a version of the 4d56 engine with a Common Rail fuel system took place in 2001. The engine was equipped with a completely new MHI TF035HL turbocharger paired with an intercooler. In addition, new pistons were used, which led to a reduction in the compression ratio to 17. All this led to an increase in power by 10 hp and torque by 7 Nm compared to the previous engine model. The engines of this generation were designated di-d (pictured) and met the EURO-3 environmental standard.

An improved DOHC cylinder head system, that is, a dual-camshaft system including four valves per cylinder (two intake and two exhaust), as well as the Common Rail fuel injection system of the second modification, began to be used on 4d56 CRDi power units starting in 2005. The diameters of the valves have also changed, they have become smaller: inlet - 31.5 mm, and exhaust - 27.6 mm, the valve stem has decreased to 6 mm. The first variation of the engine had an IHI RHF4 turbocharger, which made it possible to develop power up to 136 hp and torque increased to 324 Nm. There was also a second generation of this engine, which was characterized by the same turbine, but with variable geometry. In addition, completely different pistons were used, designed for a compression ratio of 16.5. Both power units met environmental standards EURO-4 and EURO-5, in accordance with the year of manufacture.

Important! This engine is also characterized by periodic valve adjustment; it is recommended to carry it out every 90 thousand kilometers. Their values ​​for a cold engine are as follows: intake – 0.09 mm, exhaust – 0.14 mm.

Starting in 1996, the 4D56 engine was removed from some car models, and a 4M40 EFI power unit was installed instead. The final completion of production has not yet occurred; cars in individual countries are equipped with it. The successor to the 4D56 was the 4N15 engine, which debuted in 2015.

List of car models in which it was installed

The 4D56 engine was used on the manufacturer’s assembly line to equip Mitsubishi SUVs:

• Padjero II – mid-size SUV, 1991 – 2002;
• Strada - frame large pickup truck, 1991 - 1997/1999;
• Canter – light-duty truck and special equipment, 1993 – 2002;
• Delica/Star Wagon/L300 – minibus and truck, 1986 – 1999;
• L200 – pickup truck 2 – 4 doors, 1998 – 2006;
• Delica/Space Gear/L400 – truck and cargo-passenger version, 1994 – 2007;
• Challenger - mid-size SUV, 1996 - 1998;
• Pajero Sport I – SUV, 1998 – 2008.

Mitsubishi Delica

The resulting engine characteristics allow it to be used in trucks and SUVs. Power and torque are achieved at low to medium speeds, which is especially important for off-road driving and cargo transportation.

Specifications

The displacement of the 4d56 engine in all its versions was 2.5 liters, which made it possible to produce 95 hp without a turbocharger on later models. The engine does not feature any new design solutions and is made in a standard form: an in-line arrangement of four cylinders, with a cylinder head made of aluminum, and the block is cast from cast iron. The use of just such metal alloys ensures the required temperature stability of the motor and, in addition, significantly reduces its weight.

Another feature for this engine is the crankshaft, which is made of steel and has five support points in the form of bearings. The sleeves are dry and pressed into the block, which does not allow sleeves to be made with capital. Although the 4d56 pistons are made of lightweight aluminum alloy, they are still characterized by excellent durability and reliability.

Vortex combustion chambers were installed in order to increase power characteristics and also improve environmental parameters. In addition, with their help, the designers achieved complete combustion of fuel, which increased the efficiency of the entire engine, while at the same time reducing the level of emissions of harmful substances into the atmosphere.

Since 1991, the Mitsubishi 4d56 power unit has undergone some changes. It was equipped with a special system for increased engine heating before starting. This made it possible to solve the age-old problem with operating a diesel car in winter, because from that moment on, owners of 4d56 engines forgot about the problem associated with diesel fuel freezing at low temperatures.

The same version of the Mitsubishi 4d56 engine was equipped with a turbocharger, which was air and water cooled. Its presence made it possible not only to increase power characteristics, but also to provide more confident traction, starting from lower speeds. Despite the fact that this was a new development, the turbine, judging by feedback from owners, had an excellent level of reliability and was overall extremely successful. Its breakdown was almost always associated with improper operation and poor quality maintenance work.

It should also be emphasized that the Mitsubishi 4d56 is unpretentious in operation and maintenance. After all, even an oil change can be done every 15 thousand kilometers. The high-pressure fuel pump (pictured) also had a long service life - it is replaced no earlier than after a mileage of 300 thousand km, when the plungers wear out.

Below is a table of the main technical parameters of the Mitsubishi 4d56 engine, in naturally aspirated and turbocharged versions:

Transmission identification number

The transmission type code is stamped on the information plate attached to the rear bulkhead of the engine compartment (see above). The transmission identification number is engraved on a boss molded into the top of the front wall of the transmission housing. Drive Axle Identification Number (Galant AWD models only) The axle code is engraved on a boss molded into the differential housing. Transfer case identification number (Galant AWD models only) The transfer case is not assigned a separate code. On all-wheel drive (AWD) models, the transfer case number is located on the transmission housing.

Emission Control Systems Information Label (VECI)

The VECI label contains information on the location of components of exhaust gas emissions reduction systems, specification parameters for setting up individual components, and is used in conjunction with a nameplate on which the vacuum hose routing diagram is applied. The labels are usually attached to the back of the hood. In case of loss of information or discrepancies with the equipment actually installed on the vehicle, a new label can always be ordered from the service center of the vehicle manufacturer.

Typical faults

This engine has a good degree of reliability, but like any other engine it has a number of its own “diseases”, which at least sometimes occur:

• Increased vibration levels, as well as fuel detonation. Most likely, this malfunction occurred due to the balancer belt, which could stretch or even break. Replacing it will solve the problem and it can be done without removing the engine;
• Increased fuel consumption. In this situation, there may be more than one reason. The most common is a fuel injection pump malfunction. In most cases, by 200-300 thousand kilometers it wears out significantly, as a result of which it does not create the required level of pressure, the engine does not pull, and fuel consumption increases;
• Engine oil leaking from under the valve cover. The repair boils down to replacing the valve cover gasket. The 4d56 power unit is characterized by a high degree of resistance to overheating, due to which even high temperatures rarely lead to cylinder head deformation;
• Increase in vibration level depending on speed. Since this engine has considerable weight, the first thing you should pay attention to is the engine mounts, which need to be changed every 300 thousand kilometers;
• Extraneous noise (knocking). The first thing you should pay attention to is the crankshaft pulley;
• Oil leakage from the seals of the balancing shafts, crankshaft, camshaft, pan gasket, as well as the oil pressure sensor;
• The engine is smoking. Most likely, the fault is the incorrect operation of the nozzles, which leads to incomplete combustion of the fuel;
• The engine is tripping. Very often this indicates that the piston group has increased wear, in particular the rings and liners. Also, the fault may be an incorrect fuel injection angle;
• The bubbling of antifreeze in the expansion tank indicates that, with a high degree of probability, a crack has formed in the main central bank and liquid is leaking from it;
• Very fragile fuel system return pipes. Over-tightening them can lead to rapid damage;
• On Mitsubishi 4d56 engines working in conjunction with automatic transmissions, insufficient traction is observed. Many owners have found a solution by tightening the kickdown cable;
• If the fuel and the engine as a whole are not warmed up well enough, it is necessary to adjust the automatic warm-up.

It is very important to monitor the condition of the balancing shaft belt (every 50 thousand km) and, if necessary, replace it in time. Its breakage may interfere with the operation of the timing belt, which may lead to its breakage. Some owners get rid of the balancer shafts, but in this case the load on the crankshaft increases, which can lead to it breaking at higher speeds. The bottom photo shows the engine charging system:

The turbocharger in this engine has a good service life, which is more than 300 thousand km. It is worth noting that the EGR valve gets clogged quite often, so it needs to be cleaned every 30 thousand kilometers. You should also carry out service diagnostics of the engine for errors, as this allows you to monitor changes in engine characteristics.

Important! The Mitsubishi 4d56 engine, especially the 178 hp version, really does not like low-quality fuel, which significantly reduces the overall life of the power unit. It is recommended to replace the fuel filter every 15 - 30 thousand km!

Below is the location of the Mitsubishi 4d56 engine serial number:

Vehicle identification numbers

The 17-position Vehicle Identification Number (VIN) is stamped onto a metal plate (nameplate) mounted on the instrument panel under the windshield on the driver's side of the vehicle. The VIN encrypts data such as country and manufacturer codes, vehicle type, engine and body characteristics, as well as some specific vehicle parameters.

Another information plate is riveted to the rear bulkhead inside the engine compartment. In addition to the VIN, the nameplate contains engine and transmission type codes, as well as the body paint color code. It should be noted that the information contained in the engine identification number placed on the nameplate is different and is supplemented by the meaning of the letter occupying the 8th position in the VIN. Thus, by the 4-position code 4G63 from the nameplate, you can determine that the car is equipped with a 2.0 liter SOHC/DOHC engine, however, there is no information on the configuration of the unit with a turbocharging system, while the presence of the letter U in the 8th position in the VIN code clearly indicates the presence turbocharging devices. When presented separately, the engine type code can take the following values: 4G15 - 1.5L SOHC engine 4G61 - 1.6L DOHC engine 4G93 - 1.8L SOHC engine 4G63 - 2.0L SOHC or DOHC engine 4G64 - 2.4L SOHC or DOHC engine 6G72 — 3.0 l SOHC or DOHC engine 6G74 — 3.5 l DOHC engine

In addition to the two information plates listed, there is a third one, which is a certification label and is attached to the end surface of the left front door pillar of the car. The certification label codes include information about the vehicle's production date (the year of manufacture can be determined by the letter occupying the 10th position in the VIN), as well as VIN and data on the maximum permissible loads on the front and rear axles of the vehicle (GRVW). The VIN is also recorded on the vehicle title and registration certificate. The number contains encrypted information about the date and place of production of the car, the year of manufacture of the model and the type of body.

4D56 engine tuning

It is worth noting that such a middle-aged engine as the Mitsubishi 4d56 should not be boosted. However, some owners send this engine to a tuning service, where they perform chip tuning and change the engine firmware. So, a 116 hp model can be accelerated to 145 hp and add about 80 Nm of torque. The 136 hp 4D56 engine model can be tuned up to 180 hp, and the torque ratings exceed 350 N*m. The most productive version of the 4D56 with 178 hp is chipped to 210 hp, and the torque goes beyond 450 N*m.

What do mechanics recommend?

Why does a KAMAZ diesel engine breathe?

The “golden rules” of a competent driver are as follows.

One of the main tips given by automotive industry professionals is to constantly monitor the balance shaft belt. This must be done after driving 50,000 km. The breakage of this element leads to a rupture of the timing belt, violating the safety and peace of mind of the driver. Some craftsmen are trying to improve the condition of the power unit by throwing out the shaft belts. It is strongly recommended not to commit such a rash act. The load on the crankshaft will increase, ultimately contributing to its complete breakdown. This will result in expensive repair work.

The turbocharger resource is calculated by the manufacturers for 300,000 km. After every 30,000 km, it is worth cleaning the EGR valve and not neglecting serial diagnostics. A significant role for the 4d56 Pajero Sport engine is played by the quality of the fuel poured into the tank. This is especially noticeable in the 178 hp engine. With. Poor fuel is poured - a decrease in service life should be expected. It is necessary to change the fuel filter after passing 15 thousand km.

Regarding tuning an engine that is “outdated” in the world of the car market, experts do not advise enhancing its quality. Some brave souls, however, take the car to a tuning studio, ordering a chip tuning and flashing service. In this way, 178 “horses” instantly turn into 210.

The engine was used at various times as a power plant in the Mitsubishi Challenger, Delica, L200, L300, various modifications of the Pajero, Space Gear, and Strada.

Interesting fact. UAZ owners are successfully experimenting by installing this engine. Coupled with a manual transmission, they create an excellent union.

In general, a vital device is characterized as repairable. There are no problems finding auto parts for it. The main thing is to arrive at the service station in a timely manner and subject the vehicle to diagnostic procedures, change the oil on time, and monitor the condition of the unit and its elements. In this case, you won’t have to think about repairs. It is necessary to choose a technical center without sparing time; a lot depends on the experience of specialists.

Maintainability of the Mitsubishi 4d56 engine

The Mitsubishi 4d56 engine has excellent maintainability. All elements of the piston group (pistons, connecting rods, rings, liners, etc.), as well as the gas distribution mechanism (prechamber, valve, rocker arms, etc.) are replaced separately. The only exception is the cylinder block liners, which must be replaced along with the block. Attachments such as pumps, thermostats, as well as elements of the ignition system should be replaced after a certain mileage declared by the manufacturer of the part. Below is a photo showing the location of the timing marks and the correct installation of the belt:

Pajero and its modifications (1st generation + restyling)

Let's start with the power units installed on the Mitsubishi Pajero Sport (and their modifications) of the 1st generation (including restyling). The first generation cannot please you with good quality diesel engines; there are two diesel engines in total for the first generation, the first is 4D56, the second is 4M40. There is no need to say much about the 4M40, and it is very rare to find a car with such an internal combustion engine in the Russian Federation, this is due to the purpose of the 4M40 for Mitsubishi Challenger cars (for the Japanese domestic market), so it is clearly not worth choosing a car with such an engine.

Typical problems for 4M40:

• problem with cracks in the cylinder head (coming from 4D56 engines) and the cooling system,
• timing chain stretching (on runs over 250,000 km),
• structurally weak injection pump design (contamination of the plunger pair, check valve, leaking seals),
• EGR valve (for cars with electronically controlled fuel injection pump).

The 4D56 is a much more common engine; if you pay attention to diesel, then definitely it. In the first generations (including restyling), this engine was in great demand due to its low fuel consumption (at that time) and high traction at the bottom. Despite the positive consumer characteristics of cars with 4D56, all its efficiency tends to zero, because this diesel engine is very capricious and requires constant attention.

Typical problems for 4D56:

• problem with cracks in the cylinder head and cooling system,
• rapid wear of the timing belt and balance shaft system,
• the motor can “triple”, in fact the “triple” effect is caused by the balance shafts,
• weak design of the crankshaft pulley, resulting in extraneous noise,
• structurally weak injection pump design (contamination of the plunger pair, check valve, leaking seals),
• EGR valve (for cars with electronically controlled fuel injection pump),
• weak cushions (supports) of the internal combustion engine.

With gasoline internal combustion engines, there are much fewer problems, despite the increased fuel consumption (relative to diesel engines), the design of gasoline engines turned out to be much more successful and more economical in terms of “children’s sores,” since there are practically no such problems. So, when choosing a 1st generation Pajero Sport/Montero Sport (+ restyling), you should first of all pay attention to gasoline internal combustion engines.

Typical problems for 6G72:

• contamination of the throttle assembly and airing of the system on the intake manifold, resulting in reduced traction, unstable operation at idle,
• increased oil consumption is caused by wear on the valve stem seals and rings, which can be easily solved by replacing them with new ones,
• increased noise of the internal combustion engine due to the breakdown of hydraulic compensators can be solved by replacing them,
• errors caused by oxygen sensors (there are 5 on the engine), so you should monitor their condition, as well as the quality of gasoline,
• weak engine cushions (supports),
• demands on the fuels and lubricants used.

Another gasoline engine is the 6G74, which is not widely used in the Russian Federation due to its rarity, and since this engine is based on a 6G block and belongs to the “Cyclone” line, the problems listed above about the 6G72 also apply to this to the motor. However, on the 6G74 the problem of internal combustion engine noise caused by hydraulic compensators is more pronounced, but on this engine noise can also occur due to a faulty hydraulic tensioner.

Mitsubishi 2.5 D/TD

The 2.5-liter Mitsubishi 4D56 diesel engine was produced from 1986 to 2016. It was installed on popular Mitsubishi crossovers, pickups and minibuses.

This engine became the basis for the popular diesel internal combustion engines produced by Kia / Hyundai of the D4BA, D4BF and D4BH series.

The 4D5 engine line also includes the 4D55, which was installed on Mitsubishi Galant cars, L200 pickups and Pajero SUVs from 1980 to 1986. 4D55 engines are notorious for numerous problems with the cylinder head, in particular with its cracking.

Review of faults and methods for repairing them

If the belt drive breaks, the 4D56 engine is guaranteed to bend the valve with pistons. There are not so many typical breakdowns for this power drive:

Replacing belts on that engine is not difficult; there is no need to dismantle other components and assemblies.
