3. The tighter the pump fan belt, the better.
The tighter the belt, the better. The belt is too tight, which will not only elongate or break, shorten the service life of the belt, but also cause the generator shaft, pump shaft deformation and bending and early damage of the bearing because of too much tension. The tightness of the car engine fan belt should meet the technical requirements, and the deflection of the normal belt assembly is 10-15mm.
4. The engine heats up with idle speed.
When heating with idle speed, due to the low speed, the oil pump can not quickly press the lubricating oil into the lubrication surface, the oil pressure is low, so that the engine moving parts in dry friction or semi-dry friction state work; Fuel because of low temperature atomization, so that the unburned fuel into the crankcase, wash off the oil film on the cylinder wall, will also accelerate the wear and tear of the parts.
