Diesel engine is an internal combustion engine with diesel oil as the main fuel. The combustion of fuel is carried out directly in the cylinder, releasing the chemical energy and transforming it into heat energy, using gas as the medium, and then converting the heat into mechanical energy. As the ignition of diesel fuel is spontaneous combustion by the high temperature of the compressed air, the diesel engine is also called the compression ignition (compression ignition) internal combustion engine.

The black smoke from diesel engine is caused by too much mixture and incomplete combustion. Usually it is caused by too many fuel injectors. It can stop the oil injection inspection of each cylinder of Baotou Mercedes spare parts. During inspection, if a cylinder is not injected, and the exhaust pipe does not smoke black and the engine speed changes little, it indicates that the cylinder nozzle is faulty, or the fuel injection volume of the single cylinder is too high. In this case, remove the injection pump side cover and check whether the locking nut of the cylinder has been loosened. If it is in good condition, continue to check and adjust the nozzle of the North Baotou Mercedes Benz fittings injector.

If the fuel injection volume is too large, the governor cover should be opened. Check whether the ruling line of the gear lever is moving too much into the fuel injector casing, and check whether the fly hammer of the governor is stuck.

If the fault is not detected, the injection time can be delayed slowly, and whether the exhaust pipe of the Mercedes Benz parts in the north of Baotou is still smoked. If the black smoke disappears, it is the reason that the time of the injection is premature.
