Can the engine of an imported excavator be replaced by a domestic engine

**Just an indicator in the process of buying a product or service, if you simply compare**, in fact, the consideration is not so thoughtful. **, quality, service, reputation, whether it is suitable for their own situation, etc. need to be considered together.

It should be able to be modified, several problems: 1, the engine power must be equal, or not less than the original power, otherwise the existing equipment cannot be brought away. 2. The direction of the engine must be the same, and you should understand the reason.

3. Whether the connection between the output part and the input part of the engine can be changed. If you are going to have a major surgery, it will not affect the operation. 4. Electrical part, instrument part, control part and so on.

These are all things to consider. 5, especially for the safety of the operation has no impact, this is the top priority. FYI.

It stands to reason that it is definitely OK, and it is the same as the domestic Yuchai machine, but can it be cheaper to buy a single machine?

It depends on what brand yours is, if it is EFI, the most important thing is the problem in the circuit, if it is direct injection, it will definitely be fine.

The size can be installed. No problem.

Direct injection is definitely no problem, but electric injection will be very troublesome.

Dear, hello, I'm glad to answer for you, can China produce excavator engines. Answer: It can be produced, and the excavator engine technology made in China has long been available.

Only the top excavator is equipped with a Hinatal side engine. Zhejiang Weilin Machinery Parts is a national high-tech enterprise specializing in the manufacture of excavator engine forged steel crankshafts. At present, it has formed an annual output of more than 30 kinds of different series of crankshaft models, and its wear resistance, toughness and fatigue strength are better than similar foreign products, which can completely replace imported products and fill the gap in the production of forged steel crankshafts for domestic excavator engines.

Summary. There is no difference between the engine of the car and the engine of the excavator in the structure, but there is a great difference in the computer tuning, the excavator engine belongs to the constant power work, the automobile engine is in the output power at any time in the change, the adjustment of its own oil volume and the response of the engine are very high, and the excavator engine as long as the work is stable, fuel saving and effective output of engine power. Whether it is a car engine or an excavator engine, timely maintenance is very important, and we must use a better diesel fuel to prevent serious carbon deposition in the fuel injector and cylinder of the high-pressure oil pump, which has a serious impact on power and fuel consumption.

There is no difference between the engine of the car engine and the excavator in the structure, but there is a big difference in the computer tuning, the excavator engine belongs to the constant power work, the car engine is in the output power at any time in the change, the response requirements for the adjustment of its own oil volume and the return to the line of the engine are very high, and the excavator engine as long as the work is stable and leakage, fuel saving and effective output of engine power. Whether it is a car engine or an excavator engine, timely maintenance is very important, and we must use a better diesel fuel to prevent serious carbon deposition in the fuel injector and cylinder of the high-pressure oil pump, which has a serious impact on power and fuel consumption.

Can a car engine be installed on the excavator?

It can be installed, the convex machine uses the engine on the car, the fuel injector and the oil pump and the control program uses the excavator on the original car on the line.

My engine is scrapped, and I can't change the engine assembly to a car.

Yes, no problem, look at the engine model, there are 1800 rpm and 2200 rpm, don't make a mistake with this.

The engine of the loader excavator can not be installed.

Yes, as long as the model is the same.

Car engines and loader engines do not have a speed sensor.

The electronically controlled ones have a speed sensor, otherwise they cannot be started, and the mechanical large pump does not need a speed sensor.

Because the computer version of the excavator must have an engine speed signal.

In this case, when you change the engine. You can use the shed excavation parts on the original car. The new engine is not on the mind, you can use the original car on the line. Convex machines are all the same.

There is no place for the speed sensor to be installed on the large pump.

The big pump, you use the original big blind car, I said just change the convex machine, the convex machine does not include the large lead pump. The convex machine is only the cylinder block and cylinder head, without any other accessories. In this way, as long as the engine model is the same, it must be able to be installed.

Let me add to you Komatsu is to buy out a series of Cummins, and then say that it is independently developed and produced by himself, most of the domestic excavators are Isuzu, there are also Cummins's, Kobelco's is Hinode's engine, and domestic ones like Sany Liugong Sunward Intelligence are basically Isuzu's, mainly Isuzu's engines are cheap and fuel-efficient, suitable for the Chinese market.

I have a friend who drives an excavator, and he said that there are generally many jade firewood in China, and jade firewood is powerful, and there are also Weichai use.

The excavator is not expensive in the engine, it also has only one engine, and the truck engine is not very different, but because the excavator working environment is worse than the truck, the engine requirements are higher than the truck.

The expensive aspects of the excavator are mainly concentrated in its hydraulic system, which is dominated by the main pump (converting the rotational kinetic energy of the engine into high-pressure hydraulic energy), the main valve (distributing the hydraulic energy output from the main pump to various working devices), the hydraulic cylinder (converting the hydraulic energy into reciprocating kinetic energy), the hydraulic motor (converting the hydraulic energy into rotational kinetic energy), and the hydraulic motor

In addition, the excavator chassis and cab are also quite expensive.

In addition to the engine, the truck only has a steel body, so it is relatively cheap.

There is an engine, not the same.

Generally speaking, due to the different use environment and conditions, the application principle of automobile engine and construction machinery engine (referred to as industrial machine) is different.

Car Engine:

In daily life, our requirements for cars are fast, smooth, and able to cope with short-term bad road conditions; In addition, the cooling conditions of automobile engines are more complex, and they need to face long-distance uphill and downhill slopes, which have strict requirements for emissions and noise, and have higher requirements for economic use. Therefore, for the automotive machine, we require it to have the characteristics of good acceleration, large reserve power, steep torque curve, and large reserve torque.

Excavator Engine:

The excavator needs to run continuously and continuously when working, and it also needs to deal with various complex sudden working conditions, but the speed requirements are not high.

The working machine requires continuous constant power, many operating conditions, and high reliability of continuous operation; The acceleration performance requirements are not high, basically at high speed (loaders and forklifts are more special, and there are more acceleration and deceleration conditions), because there is no vehicle machine can be cooled in the wind, and the cooling performance is high, and the emission requirements are not high.
