Experimental study on the performance of dimethyl ether engine

• 摘要：

  The experimental studies on diesel engine fueled with dimethyl ether(DME)were conducted in the aspects of exhaust emissions, power and energy consumption. The results show that DME engine smoke emissions are very low. However, at the high load condition, the CO and HC emissions are very high due to the fuel/air mixing worsening. Supercharging can improve combustion, exhaust emissions and energy consumption of DME engine. Exhaust gas recirculation (EGR) can reduce NO_x emission obviously, but at the high load and high EGR rate conditions, the combustion will be worsen. The combination of supercharging and EGR is beneficial to meet ultra-low emission regulation for the DME engine.
