What is the maximum speed of a diesel engine?

The maximum speed of a diesel engine is generally between 1,000 and 2,000 rpm.

Diesel engine; A diesel engine is an engine that burns diesel to achieve energy release. It was invented by German inventor Rudolf Diesel in 1892. To commemorate this inventor, diesel is represented by his surname Diesel, and diesel engines are also called diesel engines.

Rotational speed: The number of revolutions that an object in circular motion makes along the circumference of the circle around the center per unit time is called rotational speed (different from frequency).

Usually, the basic reason why a diesel engine emits black smoke is: insufficient and incomplete combustion of the fuel. In summary, the reasons for this incomplete combustion are mainly due to uneven fuel supply to each cylinder, poor atomization of the diesel duringcombustion, excessive fuel supply to each cylinder, insufficient air intake in the vacuum system or excessive injection time. /strong>.

Long-term black smoke indicates that there is a problem with part of the diesel vehicle. Here are some solutions:

1 When the air supply is insufficient, it's easy. black smoke. At this point we need to remove the air filter and observe the color of the exhaust smoke. If the smoke color is normal, it means the air filter is too dirty and replacing the air filter can solve the problem.

2. Generally speaking, poor diesel quality will lead to inaccurate fuel delivery, injector blockage and wear. You can try replacing the solenoid valve with a better quality diesel. If the problem is resolved, that means. that the problem lies in these two aspects.

3. Sometimes it can bewhether the fuel filter is of poor quality or has reached the usage limit and cannot effectively filter moisture and impurities present in diesel fuel. To be replaced. Try it.

4. While the engine is running, perform a cylinder-by-cylinder oil cut-off test. When a cylinder cuts off the oil, the engine speed decreases, the black smoke is significantly reduced, and the knocking noise becomes weaker or disappears, which means that the black smoke is caused by excessive oil supply into the cylinder .

5. Finally, it may be due to the widened gap between the pistons of the diesel engine. If so, it will be more troublesome and the only way is to go to the maintenance point. repair.
