Abstract

본 발명은 자동차의 엔진으로 공급되는 흡입공기의 습도를 조절하여 흡기의 노킹 방지성을 높일 수 있게 한 자동차의 엔진흡기 습도조절장치에 관한 것으로서, 엔진으로 흡입되는 공기에 수분을 공급할 수 있는 수단 및 이를 제어할 수 있는 수단을 구비하여, 엔진의 운전 상태에 따라 흡기의 습도가 알맞게 조절될 수 있게 함으로써, 엔진의 노킹 발생률을 감소시키고 이로 인한 엔진의 전체적인 성능향상을 도모할 수 있게 한 자동차의 엔진흡기 습도조절장치를 제공하고자 한 것이다.The present invention relates to an engine intake humidity control apparatus of a vehicle that can adjust the humidity of the intake air supplied to the engine of the vehicle to increase knocking prevention of the intake air, and means for supplying moisture to the air sucked into the engine; By means of controlling this, the humidity of the intake air can be appropriately adjusted according to the operating state of the engine, thereby reducing the knocking rate of the engine and thereby improving the overall performance of the engine. It is to provide an intake humidity control device.
