초록

본 연구에서는 유로형(EURO type) 클린 디젤 CRDI(common rail direct injection) 엔진용 오버플로우 밸브 성능 평가 시스템을 구현한다. 친환경 조건에 맞도록 정밀 기능을 구비한 오버플로우를 위해 스프링의 하중을 고려한 구현이 중요하다. 특히 정밀제어에 따른 디젤 차량의 성능평가는 연비 향상과 환경 규제 만족이 필연적이다. 이에 성능평가를 위한 평가 알고리즘의 기본 조건은 100cc 미만에서 3.0 bar, 150 cc 이상에서 3.3 bar, 250 cc이상에서 4.0 bar를 사용하여 시험한다.

In this paper, we have estimated the performance of an overflow valve for EURO type CRDI(common rail direct injection) engine. In order to implement the overflow valve with friendly circumstance, it is necessity for considering spring load. Especially, the performance evaluation of diesel car with accuracy control will be considered a mileage improvement and circumstance regulation. In order to evaluate the performance of overflow valve, The leak test system checks the pressure, switching time and operating time under 3.0 bar below 100 cc, 3.3 bar among 150 cc and 200 cc, finally 4.0 bar upper 250 cc.
