Matching design and application of high pressure common rail system on 135Ti diesel engine

The application of high pressure common rail electronic control fuel system on the diesel engine has been popularized in developed countries,however,the common rail system that is independently researched and developed in our country has not achieve scaled production phase.The paper discussed how to solve the problems occurred in design,manufacture and test of the electronic control high pressure pump,common rail tube and electron control fuel injector mounted in 135Ti diesel engine made in China,and comparison of pressure fluctuation simulation model of high pressure common rail system with test.
