Baotou beiben parts of engine starting difficulty, exhaust a lot of gray smoke for diesel vapor.
The reason
The engine temperature is too low, the diesel is not easy to evaporate combustion.
Injector atomization bad
The delivery time is too late.
The amount of oil under lean mixture.
The cylinder leakage is too much, can not reach the end of compression ignition temperature.
The diagnosis and treatment methods
The cold season if the engine temperature is too low, should check whether the failure of cold starting preheating device, namely Baotou beiben accessories preheater control circuit is open circuit, short circuit or heater failure phenomenon.
If the low temperature preheating device is normal, check whether the injection timing is correct. Turn the engine and insert the engine camshaft timing pin, that is, at the end of a cylinder compression TDC, check the injection pump camshaft lock pin can be inserted. If you can not insert, indicating that the timing of fuel injection is wrong, need to be adjusted.
Whether the quality of the spray should check Baotou beiben accessories to meet the requirements of each cylinder injector.
If the first two normal, should check the amount of oil is too little. Cold start, due to the low temperature in the cylinder, fuel viscosity, evaporation conditions are poor, requiring the starting oil supply than the rated fuel supply.
Finally, check the cylinder pressure, pressure far should be maintenance.
