Abstract : Electronic unit pump system is a new type fuel injection system with high injection pressure which can be applied to control fuel quantity and timing of injecting flexibly. Various Electronic Fuel Injection System have been developed and applied to different fields, all of them are still continuously being developed and consummated. We engaged late in the research of the electronic fuel injection of the diesel engine, the level is also lower. But it is the urgent task for our diesel engine industry to track the advanced technology and develop new electronic fuel injection system which is suitable for Chinese conditions
Which is a suitable electronic fuel injection system for Chinese conditions and its failure structure and principle? The process of operation and the major functions of the Electronic unit pump system are analyzed in this paper systematically. Next we had a structure analysis and assemble test on the most important part of this system, that is the electronic unit pump. Last the trouble of the Electronic fuel Injection System has been analyses and serviced.
With the advantage of the Electronic unit pump has been standing out .This technology will be widely used. So the research will help people get a better using and safeguarding of this pump.
Key Words : Electronic Unit Pump ; Diesel ; Injection System;Trouble; structure and principle
