Abstract

This paper is a purpose to study and analyze the failure examples for timing belt, camshaft position sensor and ignition coil of LPG automotive engine. The first example, whe the service man install the front case bracket of engine, he excessively tightened up a 12mm bolt for being fixed of brackct. As a results, the bolt was separated from joint part so that it was put in between the crankshaft sprocket. Therefore the belt was broken off because of interference between timing belt and sprocket tooth. The second example, it verified the disharmony phenenomen of engine that the gap of the camshaft position sensor and camshaft senseing point assembled on cylinder head part was small more than iregular value so that the it was generated senseing damage phenomenon by pulse signal misconduct. The third example, it was found the engine disharmony phenomenon that the fire in the ignition coil was leaked by inner damage of Number 2 ignition coil.Therefore, the the manager of a car throughtly have to inspect not in order to arise the failure symptoms.

이 논문은 LPG 자동차 엔진의 타이밍벨트, 캠샤프트포지션센서 및 점화코일에 대한 고장사례에 관련된 연구이다. 첫 번째 사례는, 엔진의 프론트 케이스 브래킷장착을 할 때 12mm 볼트를 조이면서 과대한 토크로 인해, 볼트가 체결부에서 분리되어 크랭크축의 스프로킷에 끼여 타이밍벨트와 스프로킷의 이사이에 벨트 간섭에 의해 벨트가 끊어진 것을 확인하였다. 두 번째 사례는, 실린더 헤드부에 설치되어 있는 캠샤프트 포지션 센서와 캠축 감지부의 간극이 너무 작아 센서의 펄스신호불량에 의한 컴퓨터의 인식불량으로 인해 엔진의 부조화현상이 발생된 것을 확인하였다. 세 번째 사례는, 2번 점화코일의 내부불량으로 인해 점화를 할 때 점화코일에서 불꽃이 누설되어 엔진의 부조화 현상이 발생된 것을 확인하였다. 따라서, 차량관리자는 이러한 현상이 발생되지 않도록 철저한 차량점검을 해야한다.
