| 摘 要： | 二甲醚(DME)是一种重要的超清洁能源产品,文中分析了二甲醚的理化特性,并在D1110柴油机上掺烧D90(二甲醚柴油质量分数比9:1),结果表明:功率和转矩略低于原柴油机,PM排放大幅度下降,NOx在整个负荷范围内得到控制.结果体现了柴油机燃用二甲醚柴油混合燃料在降低排放方面的优越性能.

| Abstract: | DME is an important mean of ultra-clean energy products.The paper analyses the physical and chemical properties of Dimethyl Ether(DME),the diesel engine blends with D90 fuel(the ratio of DME and diesel in the mass: 9 to 1),and the testing results show that engine power and torque decrease compared with the original diesel engine,PM emission largely decreases,and NOX emission is under control at all the load scale. |
