Abstract
Description
Claims (1)
- 대형 디젤 엔진용의 대형 연료 분사 밸브(1)를 그 밸브(1)의 입구측에 압축 오일을 공급함으로써 테스트하며, 입구측에서의 오일 압력을 점진적으로 상승시키면서 기록하는 것인 테스트 방법에 있어서,분사 밸브(1)의 개방 압력을 초과하여 입구측의 압력이 강하하는 순간에 입구측에 오일 압력을 제공하는 압축 공기의 공급을 일시적으로 중단함으로써 분사 밸브의 개방 압력을 일시적으로 유지시키고, 그 후에 개방 압력을 현재 상태의 분사 밸브가 엔진에 사용하기에 적합한 가를 결정하는 데에 사용하는 것을 특징으로 하는 방법.
