摘　　要：在丰田8A型汽油机上开展了汽油/二甲氧基甲烷(DMM)含氧混合燃料的性能与排放特性研究,得到了不同节气门开度、转速和负荷下的发动机性能和排放参数,为在汽油机上使用含氧燃料提供了试验依据。研究结果表明:在相同平均有效压力下混合燃料的燃油消耗率有所增加,但折算成当量汽油的燃油消耗率下降,热效率提高。CO和HC排放随混合燃料中含氧量的增加而降低,但NOx排放变化不大。The study of engine performance and emissions has been carried out in Toyota 8A gasoline engine fuelled with gasoline/dimethoxymethane blends. The experimental results show that the effective brake fuel consumption is increased while the gasoline equivalent fuel consumption is decreased and the engine thermal efficiency is improved compared with those of gasoline fuel. Meanwhile, the exhaust CO and HC will decrease with increase of oxygenate in fuel blends. However, addition of DMM in gasoline has little influence on NOx emission.
