Abstract

Abstract

By contrasting the testing results of engine fueled with dimethyl ether (DME) blends and gasoline, this paper evaluated the practical characteristics of different component and the ratio of DME blends on spark ignition engine. The investigation and analysis of power performance, fuel economy and idle emissions were carried out on spark ignition engine fueled with two different ratio blends, which were made up of DME, liquefied petroleum gas (LPG) and methanol. The results indicate that the antiknock property of DME-LPG blends is better than that of gasoline, through adjusting the fuel supplying and ignition system of engine, the power of DME-LPG blends is greater than that of gasoline at low and middle engine speed, lower than that of gasoline at high engine speed, the specific fuel consumption of DME-LPG blends is lower than that of gasoline under all range of load, the HC, CO and NO_x emissions of DME-LPG blends are obviously reduced compared with gasoline under idling condition. The performance of DME-LPG blends engine is generally the same as that of gasoline engine.
