The fuel leaks into the oil basin, the plunger of the diesel engine fuel injection pump wears too much, the injector needle is not closed tightly or the needle valve is stuck in the open position; the clearance between the piston, the piston ring and the cylinder is too large, so that Fuel leaks under the cylinder wall to the oil sump.

It takes a while for the oil film to re-establish between the crankshaft and the bearing, between the piston and the cylinder liner after the engine is started. The optimum clearance between moving parts can only be obtained after the engine parts reach the normal working temperature. Therefore, with the engine's heat engine, the engine speed is gradually increased from no-load speed 650r/min to 1000-1200r/. The preheating operation of the diesel engine is carried out at min.
The main purpose of the diesel generator control panel is to distribute the electrical energy output by the generator to the user load or the electrical equipment. It is also used to indicate the operation of the diesel generator and to maintain the voltage stability of the generator under load changes. The control panel is generally equipped with a voltmeter, a frequency meter, an ammeter, a power meter, a three-phase current conversion switch, a three-phase voltage conversion switch, a voltage setting knob, and various indicator lights.
