- 燃料噴射バルブ(1)の入口側の油圧を記録しながら、この油圧を徐々に増加するよう、燃料噴射バルブ(1)の入口側に加圧されたオイルを供給することにより、ジーゼルエンジンの燃料噴射バルブ(1)をテストするための方法において、
燃料噴射バルブ(1)の入口側の圧力の低下に対応し、燃料噴射バルブ(1)の開放圧力を越えた瞬間に、圧力の増加を、電子的に瞬間的に停止し、この瞬間に、燃料噴射バルブ(1)の入口側に油圧を供給するための圧縮された空気の供給を停止し、その後、開放圧力を使用して、現在の状態の燃料噴射バルブ(1)が、エンジン内での使用に適しているかどうかを判断することを特徴とする、燃料噴射バルブをテストするための方法。
