Sealed garbage truck engine power shortage reasons

What are the reasons for the lack of power of the sealed garbage truck diesel engine? The lack of diesel engine power refers to the engine can not reach its rated power and maximum speed, the main reasons are as follows: plug the fuel tank vents, oil out of the fuel tank switch or loose low-pressure pipe joints. Diesel filter plugged. Air filter plugged. There is air in the oil or moisture in the diesel. Insufficient oil supply to the pump. Fuel injection pump is uneven or insufficient. The injection time is too early or too late. The fuel pump manipulator will not be able to reach the maximum fuel supply position. Governor improperly adjusted.

Individual cylinder injectors are poorly sprayed and the diesel atomization quality is poor. Sealed garbage truck injection pump worn or even stuck. Piston rings wear excessively. The valve mechanism of the valve train is not strict. The engine is blue, mainly due to burning oil. The following are some common causes of malfunction: Excessive oil in the air filter. The oil in the oil filter of the air filter is too much. In the case of a hot car, the oil becomes thin and can easily be brought into the cylinder to burn, causing the engine to emit blue smoke. The oil level in the oil ring of the piston ring cannot exceed the oil level. Surface ring groove. Excessive oil in the sump. The oil in the oil pan is too much, and the oil splashed on the cylinder wall also increases accordingly. Some of the oil squeezes into the combustion chamber from the gap in the piston ring and burns, resulting in blue ripples.

After the piston ring of the sealed garbage truck is worn out, the gap between the piston ring and the cylinder sleeve is too large. When the piston ring is cemented with coke, the wear of the piston ring and the gap between the cylinder sleeves are too large. The ability to reduce the turbidity, the oil scumming, will cause the cylinder liner to row. The trachea emits blue smoke, and it can also discharge oil when it is serious. Cylinder liner and piston set grinding table is not good. In a new or overhauled locomotive, the cylinder liners and the pistons and piston rings have not been well-grounded. Since the piston rings cannot clean the oil on the cylinder walls when they start working, they will also emit blue smoke. However, after a period of running-in, you can eliminate it yourself.
