Abstract

본 발명은 가솔린엔진의 냉각시동용 흡입공기 가열장치에 관한 것으로서, 자동차의 전원공급부(90)에 전기적으로 연결되어 엔진 기동시에 작동되며, 흡기다기관(6)내부의 원주에 걸쳐 설치되어 스로틀바디(2)로부터 흡입되는 공기를 가열하는 제1가열히터(50)와, 상기 흡기다기관(6)과 연통된 실린더헤드(8)의 흡입포트(10)내부의 원, 주에 걸쳐 설치되어 상기 제1가열히터(50)로부터 1차로 가열된 흡입공기를 재차 가열하는 제2가열히터(60)를 포함하는 것을 특징으로 하여 흡입공기와 가솔린을 가열하여 가솔린의 기화를 도와 시동성 및 초기 아이들링상태를 향상시킴으로써, 배기가스를 줄이고 엔진의 수명의 연장시킬 수 있도록 한 것이다.The present invention relates to an intake air heating device for cooling start of a gasoline engine, which is electrically connected to a power supply unit 90 of an automobile and operated when the engine is started. 2) a first heating heater 50 for heating the air sucked from the air, and a circle and a state inside the suction port 10 of the cylinder head 8 communicating with the intake manifold 6; And a second heating heater 60 which heats the suction air primarily heated from the heating heater 50 again to heat the suction air and gasoline to help vaporize the gasoline to improve startability and initial idling state. This helps to reduce emissions and extend engine life.
