Simulation on Diesel/DME Mixed Injection System

Dimethyl ether (DME) is a promising and excellent alternative fuel for compression ignition DI diesel engines. In addition to the significant merit of no soot emission, DME would be of better ignition quality, lower auto ignition temperature and better atomization compared with diesel. The paper presents models and simulates fuel injection system of diesel/DME engine. Simulation calculation proven that DME could injected into mixed cavity propitious and mixed rather equality with diesel. Injecting characteristic of fuel system was impacted by blended DME, and the incidence came along with DME proportional.
