Abstract

본 발명은 열전소자를 이용한 엔진의 흡입공기 온도조절장치를 개시한다. 개시된 장치는, 엔진으로 흡입되는 공기통로상에 설치되는 원통형관과, 상기 원통형관의 내부에 설치되어 흡기관을 통해 연소실로 흡입되는 공기와 열교환작용을 하는 열전소자와, 외기온도 및 엔진 내부의 온도변화에 따라 열전소자의 구동을 제어하는 열전소자 제어수단을 포함한다. 따라서 엔진의 상태에 따라 연소실로 흡입되는 공기의 온도를 조절할 수 있게 됨에 따라 엔진의 예열시간을 단축시켜 배기가스중의 유해성분을 줄일 수 있게 되고, 엔진의 정상상태에서는 연소실로 흡입되는 공기를 냉각시켜 엔진의 냉각작용을 하게 한다.The present invention discloses an intake air temperature control apparatus for an engine using a thermoelectric element. The disclosed apparatus includes a cylindrical tube installed on an air passage sucked into an engine, a thermoelectric element installed inside the cylindrical tube and performing heat exchange with air sucked into a combustion chamber through an intake pipe, an outside air temperature, and Thermoelectric element control means for controlling the driving of the thermoelectric element in accordance with the temperature change. Therefore, the temperature of the air sucked into the combustion chamber can be adjusted according to the engine condition, thereby reducing the preheating time of the engine and reducing the harmful components in the exhaust gas.In the normal state of the engine, the air drawn into the combustion chamber is cooled. To allow the engine to cool.
