The function of the automobile oil control valve is to adjust the oil pressure and prevent the oil pressure of the oil pump from being too high. At the time of high speed, the oil supply of the oil pump is obviously large, and the oil pressure is also significantly high, at this time, it is necessary to intervene in adjustment. Burning oil will cause the burning oil to cause the vehicle oxygen sensor to be damaged too quickly; Burning oil will lead to increased fuel consumption, excessive exhaust emissions, unstable idle speed, enhance the hidden dangers of the car, and increase the economic burden. Burning oil will lead to increased carbon accumulation in the engine combustion chamber, weak acceleration, slow speed, lack of power and other adverse consequences
