    Abstract
  • This paper measured the combustion characteristics of different fuels on the spark ignition engine with CB-566 combustion analysis instruments, studied the influence of DME-LPG blends fuel on the combustion process of spark ignition engine, and compared it with that of gasoline. It is pointed that the flame development angle and combustion duration of DME-LPG blends fuel engine are longer, maximum cylinder pressure is higher than that of gasoline engine. The two engines are alike in combustion characteristics. The results indicate that the additive with high octane number and high heat volume to dimethyl ether (DME) improves the quality of DME greatly, and the spark ignition engine without changing its structure can use DME-LPG blends fuel.
