为保证发动机正常工作,机油泵的压力和主油道的机油压力必须适当。当发动机转速增高或机油变浓时,机油压力就会增高,使飞溅到气缸壁上的机油过多,机油大量进入燃烧室,造成积炭和机油消耗量增 In order to ensure the normal operation of the engine, the pressure of the oil pump and the oil pressure of the main oil gallery must be appropriate. When the engine speed increases or the oil becomes thick, the oil pressure will increase, so that the oil splashed on the cylinder wall too much oil into the combustion chamber in large numbers, resulting in carbon deposition and oil consumption increased
