Abstract

In this paper, we have implemented an overflow valve for EURO5 Type and the performance evaluation system based on IT. On injecting a diesel oil into an engine, it is necessity for an overflow valve that can sustain an engine oil status in front of the engine. In order to evaluate the performance of overflow valve, we need the leak test system with IT. The leak test system checks the pressure, switching time and operating time.

본 연구에서는 EURO5형 엔진의 오버플루밸브 및 성능평가 시스템을 구현한다. 친환경 조건에 맞도록 정밀기능을 갖도록 개발하고, 정밀측정이 가능하도록 사용이 용이한 성능평가 시스템이 필요하다. 특히 정밀제어에 따른 성능평가는 연비가 향상되고, 환경규제를 만족한다. 이에 정밀측정 성능검사기(10cc 미만에서 3.0 Bar, 150 cc 이상에서 3.3 Bar, 250 cc이상에서 4.0 Bar)를 사용한다.
