Abstract

본 발명은 차량엔진의 실화 검출장치 및 그 방법에 관한 것으로, 보다 상세하게는 차량엔진의 각 기통에 설치된 센서에 의해 연소상태를 파악하므로서 엔진실화를 감지할 수 있는 장치 및 그 방법에 관한 것이다.The present invention relates to an apparatus and method for detecting misfire of a vehicle engine, and more particularly, to an apparatus and method for detecting engine misfire by detecting a combustion state by sensors installed in respective cylinders of a vehicle engine.

본 발명은 차량엔진의 실린더내부에 압력감지센서를 장착하여 실린더 내의 연소시에 발생되는 압력을 직접감지한 후 컴퓨터부에 감지된 압력값을 인가하므로서 컴퓨터부에서는 이를 설정된 압력값과 비교판단하게 된다.According to the present invention, a pressure sensor is mounted inside a cylinder of a vehicle engine to directly detect the pressure generated during combustion in a cylinder, and then apply the detected pressure value to the computer unit, and the computer unit compares it with the set pressure value. .

즉 입력압력값이 설정압력값 보다 작게되면 실화(misfire)로 판단하게 된다.따라서 실화(misfire) 검출방법이 엔진의 실린더내부에 발생되는 연소시의 압력압력값을 직접 감지하여 판단하므로 실화감지가 정확하고 주변 노이즈(noise)에 의한 오판단이 크게 줄어들게 된다.In other words, if the input pressure value is smaller than the set pressure value, it is judged as misfire. Therefore, the misfire detection method directly detects and determines the pressure pressure value at the time of combustion generated inside the cylinder of the engine. It is accurate and greatly reduces the misjudgment caused by the ambient noise.
