Abstract

본 발명은 자동차 기관의 환기구조에 관한 것으로서, 엔진오일의 열화를 지연시켜 주기 위해, 기관 상부에 헤드커버(13) 일측에 흡기다기관에 연통되는 크랭크실환기밸브(22)가 연결되고, 공기여과기에 연통되는 벤트호스(21)가 상기 헤드커버 타측에 연통되는 것에 있어서, 상기 기관의 크랭크실 하부에 압력제(30)가 내부와 연통되게 장치되고, 상기 압력계에서 감지된 압력상태를 인가받는 제어기(31)가 상기 크랭크실환기밸브에 제어 가능하게 연결되어, 상기제어기가 인가받는 압력상태에 따라크랭크실환기밸브(22)의 개폐량이 조절되도록 구성하여, 압력계(30)에 의해 크랭크실 내의 압력이 계측되고, 이 압력이 제어기(31)에 인가되어 기준치 이하일 때는 크랭크실환기밸브(22)를 통해 배출되는 유량이 증가되도록 하고, 인가된 압력이 기준치 이상일 때는 제어기(31)에서 크랭크실환기밸브(22)를 조절하여 배출되는 유량이 감소되도록 하는 자동차 기관의 환기 제어장치이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation structure of an automobile engine, in order to delay deterioration of engine oil, an crankcase ventilation valve 22 connected to an intake manifold on one side of the head cover 13 is connected to an upper portion of the engine, and an air filter In the vent hose 21 communicated with the other side of the head cover, the pressure agent 30 is installed in the lower part of the crank chamber of the engine to communicate with the inside, the controller is applied to the pressure state sensed by the pressure gauge 31 is controlably connected to the crankcase ventilation valve, the opening and closing amount of the crankcase ventilation valve 22 is adjusted according to the pressure state applied by the controller, so that the pressure in the crankcase by the pressure gauge 30 When the pressure is applied to the controller 31 and is below the reference value, the flow rate discharged through the crankcase ventilation valve 22 is increased, and when the applied pressure is above the reference value, The controller is a ventilation control apparatus of the vehicle engine so that 31 controls the crankcase ventilation valve 22, the flow rate is reduced is discharged from.
