Fuel supply system failure caused sudden shutdown.

This kind of shutdown phenomenon is caused by gas entering the oil supply circuit of the engine or oil supply interruption. Before the engine suddenly stopped, the number of revolutions fluctuated and the working temperature was not fixed.

The causes of oil supply interruption are: insufficient diesel tank oil, should add enough fuel; Oil circuit seal is not tight.

When such a failure occurs, it can also be judged by the method of emptying the fuel system after shutdown.

If the oil is pumped with a hand pump and a lot of foamy oil bubbles are released at the air drain screw, the shutdown is caused by oil and gas in the oil.

The tightness of the low pressure oil circuit should be carefully considered. The injection pump camshaft is broken or the rolling key is broken, the connecting plate is broken, and the injection pump should be repaired.

Engine crankshaft lock causes sudden stop, stop, observe whether the water temperature is abnormal, oil pan whether there is water (oil is emulsified).

If the check is no problem, the engine engine crankshaft should be rotated, if it feels laborious or unable to rotate, it can be judged as burning the bearing shell or holding the engine crankshaft after burning the bearing shell.

After the failure of the burning bush, it is necessary to find out the cause, clean the oil passage, grind the engine crankshaft, replace the bearing bush and a few parts (connecting rod, etc.) before assembling the test machine.
