Open publisher page 3 citations

Abstract

A double electronic valve fuel system is established based on an electronic unit pump and injector of common rail system,that can realize the independent control of fuel injection and fuel supply.Principle of this fuel system is studied.Control parameters of the fuel injection electronic valve and fuel supply electronic valve are changed in experiment.In this test,different fuel supply characteristics with the same oil output and high pressure in low speed can be reached.The result shows that high pressure in low-speed and flexible adjustable injection rate can be attained.
