| Abstract: | The structure of low-pressure common-rail fuel injection system of DEM （dimethyl-ether） engine is reasonably simplified, and the mathematical model of fuel injection process is established. Matlab/Simulink is used to simulate the solenoid valve pulse and power supply control valve lift curve in different speed conditions of DEM engine, with which the DME injection law in the low-pressure common-rail system has been obtained. These provide simulation methods and theoretical basis for the designing of new fuel injection system of DEM engine. |
