Lack of diesel engine performance: speed can not be improved to the proper index, each cylinder work is not uniform, acceleration is ineffective, or enter the vehicles loaded with sand, mud and other feel powerless. The following parts and conditions should be observed.

(1) when the oil pressure is normal, the engine runs smoothly, and the exhaust pipe doesn't smoke when the air temperature is idle. Under the rated load, there is a small amount of black smoke coming out of the exhaust pipe at the moment of the emergency refueling door.

(2) the oil pressure is normal. When the idle speed is running, the engine is slightly trembling and knocking, and a small amount of black smoke is discharged from the exhaust pipe.

(3) the oil pressure is normal. The Baotou Bei Ben heavy duty truck engine is not smooth at high speed, accelerates insensitivity, and the exhaust pipe is white smoke or black smoke. The temperature of the engine is too high, usually due to the late oil supply time.

(4) the oil pressure, engine operation is not smooth, the exhaust pipe smoke vapor like white smoke, the broken oil test, the difference of each cylinder work may have little water in diesel exhaust pipe; a row of black smoke, may be Baotou beiben accessories individual cylinder not working or air filter plug.

(5) Baotou beiben parts of oil pump low pressure or pressure gauge diesel engine running hand did not rise, not smooth, do not smoke or exhaust smoke is few, there is a general air into the low-voltage circuit, or by dirt blocking, or poor performance of oil pump.
