Baotou beiben heavy truck engine power shortage of parts, the exhaust pipe exhaust smoke gray, is generally too late due to injection time. At this time not only high-speed operation is bad, acceleration is not sensitive, and the temperature is too high.
The reason
The fuel injection advance angle is too small.
Injector atomization bad.
Engine temperature is too low.
The cylinder is in the water.
Water in diesel.
The diagnosis and treatment methods
Lack of the engine exhaust pipe, exhaust smoke gray, first hand on the muffler outlet, if the left hand drops, it should check the diesel cylinder and has no water (or not in accordance with the difficulty of starting the engine starting and exhaust white smoke fault repair).
When the engine is just starting to run gray smoke, the cause of the temperature is too low at the start, part of the diesel fuel evaporated into steam, not directly caused by the combustion. If the engine temperature increases after the gray smoke gradually disappeared, it is a normal phenomenon. If the engine just starting when at elevated temperature and gray smoke, black smoke, the cylinder pressure is insufficient, while the combustion conditions improved, but still can not completely diesel combustion, the engine power is insufficient to cope with cylinder pressure check.
The Baotou beiben heavy truck engine power shortage of parts, the exhaust pipe ash white smoke, is usually caused by fuel injection advance angle is too small. If the engine temperature is too high, slow speed, can be considered as fuel injection time is too late. If this phenomenon occurs suddenly, the fuel injection pump shaft relative to the fuel injection pump gear rotation lead to too small fuel injection angle. Adjustment of fuel injection timing.
Finally, check the Baotou beiben Heavy Truck Parts Injector atomization, and adjustable injector.
