Diesel engine burns diesel to obtain energy release. A prerequisite for the normal operation of a diesel engine is that well-atomized diesel can be injected into the combustion accurately and timely.
The compressed air in the room and the combustion chamber must reach a sufficient temperature to catch fire and burst. To meet these two conditions, it is necessary to have a sufficiently high speed and make cylinders have a certain temperature. When the diesel engine cannot be started, it should look for reasons from the start-up work, diesel fuel supply system and compression.
Possible cause one: Diesel engine cannot start due to low ambient temperature. In the case of low temperature, the diesel engine should be warmed up, otherwise it will not be easy to start.
Probable cause two: The diesel engine cannot start due to low starting speed.For a diesel engine that is cranked by hand, gradually increase the speed, and then move the pressure reducing handle to non-decompression position so that there is normal compression in the cylinder. If the pressure reducing mechanism is not adjusted properly or the valve is against the piston, it will often feel difficult to shake the car. It is characterized by the crankshaft turning to a certain
One part won’t turn, but it can be returned. At this time, in addition to checking the decompression mechanism, you should also check whether the timing gear meshing relationship is wrong. And for using electric starter, if the starting speed of the diesel engine is extremely slow, most of the engines are weak, which does not mean that the diesel engine itself is faulty.
