| Abstract: |
| Considering the pressure wave variation of the weared pair-parts in fuel system of diesel engine,the pressure waves of the plunger pair,fuel delivery valve pair and needle valve pair of fuel injector were measured under the weared conditions with the method of distinguishing the pressure waves in high pressure pipes so as to study the wearing degrees of the pair-parts. |
| Key words: fuel system,pair-part,wearing,fuel pressure wave, |
