Brief Introduction Of Idling Speed Increase Of Wrecker

When using idling speed to heat up, due to the low speed, the oil pump cannot press the lubricating oil into the lubricating surfaces quickly, and the oil pressure is also low, so that the moving parts of the engine work under dry friction or semi-dry friction; the low temperature of fuel Poor atomization causes unburned fuel to flee into the crankcase, wash away the oil film on the cylinder wall, and also accelerate the wear of parts. Therefore, a few seconds after the engine is started, the fast idle speed is applied to improve the lubrication conditions of the engine.
