| Abstract: | To increase the service life of diesel engine's high-pressure fuel pipe,and prevent it from breaking,investigation has been carried out on both design and production technologies.The advantages and disadvantages of varied technologies are comapred and stuied.Based on a particular diesel engine,stress of high-pressure fuel pipes under different self-strengthing pressure are investigated.The comparison results show that self-strengthing technology may reduce the stress in high-pressure fuel pipe and increase ... |
