Abstract

본 발명은 내연기관에 사용되는 연료의 예열장치에 관한 것이다.The present invention relates to a fuel preheater for use in an internal combustion engine.

종래에는 엔진에 공급되는 연료가 연료탱크(10)에 저장시의 낮은온도를 유지하며 그대로 엔진의 실린더속으로 들어가기 때문에 연소실에 분무되어 연소될때 착화 및 발화가 늦어져 불꽃의 전달속도 즉 연소속도가 느리기 때문에 연료가 완전 연소되지 않아 배기개스에 유독 성분이 발생되어 공해가 발생되고 엔진의 출력이 떨어지며 노킹현상이 일어나 내연기관의 수명을 단축시키는 폐단이 있었다.Conventionally, since fuel supplied to the engine maintains a low temperature when stored in the fuel tank 10 and enters the cylinder of the engine as it is, ignition and ignition are delayed when sprayed and combusted in the combustion chamber, so that the flame delivery speed, that is, the combustion speed is slow. Therefore, the fuel is not completely burned, so toxic components are generated in the exhaust gas, causing pollution, lowering the engine output, knocking, and reducing the life of the internal combustion engine.

따라서 본 발명은 상기와 같은 폐단을 해소하고자 안출된 것으로, 연료탱크(10)에서 실린더로 흡입되는 연료를 배기매니폴드에 설치된 연료예열장치로 통과시키면서 엔진의 열과 히터의 열로 폭발에 적당한 온도로 가열하여 연소실에서 연소시 착화, 발화 및 불꽃전달속도 즉 연소속도가 최상의 상태로 공급되도록 함에 따라 완전연소를 이루도록 하므로 유해개스의 양을 줄여 대기오염을 방지할 수 있고, 고출력의 엔진을 얻을 수 있음과 동시에 기관의 수명을 길게 보호할 수 있도록 하는데 그 목적이 있다.Therefore, the present invention was devised to solve the above-mentioned waste end, and the fuel sucked into the cylinder from the fuel tank 10 is passed to the fuel preheater installed in the exhaust manifold and heated to a temperature suitable for explosion by the heat of the engine and the heat of the heater. It is possible to achieve perfect combustion by ignition, ignition and flame transfer speed, that is, the combustion speed is supplied in the best state during combustion in the combustion chamber. Therefore, it is possible to reduce the amount of harmful gas to prevent air pollution, and to obtain a high-power engine. At the same time, the aim is to be able to protect the life of the organ for a long time.
