The Mitsubishi 4M4 engine is a series of four-cylinder diesel engines first introduced by Mitsubishi Motors Corporation, the third generation of its Montero Pajero SUV. They replaced the previous family of 4D5 engines, and no new engine has been able to replace them to date.

4m40, that's the classic Mitsubishi engine. While you won't find much of the current trendy technology in this engine, it's still employing a simple single-camshaft construction. But it's quite durable, and its reliability has been well proven.

Cons:

1. High noise, valve sound, the consistent characteristics of Mitsubishi machine, regardless of high-end and low-end.

2. Thermostat.

There are many problems, and I don't know if there is any improvement now.

3. Spark plugs.

The hole seal opening is small, making the spark plug sleeve difficult to insert. It is easy to damage the seal.

There is a resonance zone between 3000 rpm, which is very noisy, and it is quiet above or below this speed.

5. The original high-voltage line.

The quality is poor, and it will not work after several plugging and unplugging, so it is recommended to change to a sturdy modification line.

6. Cold start in winter.

There may be a pulley whistle and the hot car disappears.

7. Due to engine reasons, there is little difference between the sound insulation of the heartbeat version. Gearbox.

Mitsubishi's F5M41 has the characteristics of large torque capacity, high transmission efficiency, low vibration and noise, easy maintenance, light gear change, etc., due to the use of advanced synchronization technology such as double cone, making the shift operation very light and reliable. To say, before the second half of 05, this gearbox used single bevel gear technology, so the previous gearbox was more difficult to hang on to the 1-2 gears.

After that, double bevel gear technology is used, so the gear is smooth and easy. Clutch.

A total of three have been used: Mitsubishi, Chongqing Daikin, Changchun Yidong, Mitsubishi and Daikin are good, Yidong is not very stable, sometimes there is a start-up shaking. Most of the cars that are now loaded and may be Daikin.

The hydraulic clutch is used, and the hydraulic pedal of FML is too light, and the foot feeling is not as good as that of Racehorse and Ling Shuai.

Each has its own merits, and they are all very good engines

It is a multi-point EFI engine of displacement, and I adopt it for swimmingInhale naturallyThere are a total of 4 cylinders arranged in the shape of an L.

Gasoline engine.

Gasoline Engine is a Zen engine that converts internal energy into kinetic energy using gasoline as fuel. Since gasoline is less viscous and evaporates quickly, gasoline can be injected into the cylinder with a gasoline injection system, after compression reaches a certain temperature and pressure.

Use a spark plug. ignites to make the gas expand to do work.

The gasoline engine is characterized by high speed, simple structure, light weight, low cost, stable operation, and convenient use and maintenance. Gasoline engines are on cars, especially small cars.

on a large number of uses.

Due to the small viscosity of gasoline and fast evaporation of gasoline, gasoline engines can form a uniform mixture with air outside the cylinder, and then suck the mixture into the cylinder, or use a gasoline injection system to inject gasoline into the cylinder to make the gas expand and do work.

The disadvantage of gasoline engines is thermal efficiency.

It is lower than that of the diesel engine, the parking consumption is higher, the ignition system is more complex than the diesel engine, and the reliability and maintenance convenience are not as good as the diesel engine. The gasoline 4G69 engine is an engine produced by Mitsubishi in Japan. The 4G69 engine is a very mature technology with a failure rate.

Very low, powerful engine. Maintenance is also cheap, and the 4G69 engine is used in many models.

Mitsubishi engine models include 4G G G G, 61 AND SO ON. Mitsubishi announced that the next-generation Mitsubishi EVO will no longer feature the 4G63 engine. Now, EVO has evolved into its 10th generation, and the 18-year history of EVO is "tried-and-test".

Mitsubishi engine**.

The 4G63 does not occupy the altar like the Renault F1 racing car RS26 engine, which makes people look up to it. Although the M4G63 has given one surprise after another in the nearly 20 years since its debut, 4G63 is a civilian 4G63 through and through.

Not only can he be found on the EVO, but he is still an absolute workhorse in civilian cars such as the Lancer - even including many non-Mitsubishi brands, such as domestic Zhonghua, Chery and other models.

The model number is 8A80.

Starting from the M100, the V8 engine has gone through multiple generations of models such as M116, M119, M113, M273, and M278. From the original 16-valve single overhead camshaft mechanical fuel injection engine, it has evolved into a 32-valve overhead camshaft in-cylinder direct injection engine, and has advanced engine technologies such as double overhead camshafts, dual continuously variable valve timing, variable length intake manifolds, and twin turbocharging.

Mitsubishi has its own V8 engine, model 8A80, and uses Mitsubishi's own in-cylinder direct injection technology (GDI technology), the maximum known displacement is: It has a maximum horsepower of 280ps at 5000rpm and a maximum torque of 412Nm at 4000rpm.

Above, 8a80, engine.

This engine was previously used in Mitsubishi's high-end sedans "Proudia" and "Dignity", and legend has it that the "Dignity" was once a special car for the Japanese imperial family, and money could not buy it.

The picture is "proudia".

However, these two series of cars have been completely discontinued.

Later, Mitsubishi cooperated with Hyundai for technical exchanges, and now this engine has been used in Hyundai's high-end sedan Yakos.

The picture shows the first-generation Accos sedan.

South Korea's Hyundai Group simplified and optimized the engine, and named it OMEGA

Hope it helps.

Mitsubishi company does not have its own mature 8-cylinder gasoline engine, the current maximum displacement is only V6, that's it, if you see an ordinary car with the words V8, it is not a person who knows how to stick it in order to save face, and then some non-ordinary passenger cars may use Mitsubishi's diesel engine.

Mitsubishi V8? This is a diesel engine, and the largest gasoline production engine is the V6 liter on the Pajero.
