摘　　要：针对甲醇、生物柴油和聚甲氧基二甲醚PODE的优势,为了改善经济性,在一台CY25柴油机上分析不同引燃燃料对甲醇预混合气引燃燃烧模式经济性的影响。试验结果表明:两种甲醇预混合气引燃模式在小负荷时有效热效率有大幅度增长,且经济性较好。引燃模式受甲醇质量比影响很大,两者在不同质量比范围内,经济性表现不同。PODE引燃模式总体相较生物柴油引燃模式还是有较好的经济性。Based on the advantages of methanol,biodiesel and poly(methoxydimethyl ether)(PODE),in order to improve the economy,the effects of different pilot fuels on the economy of methanol premixed pilot combustion mode were analyzed on a cy25 diesel engine.The experimental results show that the effective thermal efficiency of the two kinds of methanol premixed ignition modes increases greatly at low load,and shows good economy.The ignition mode is greatly affected by the mass ratio of methanol,and the economic performance of the two modes is different in different mass ratio ranges.Compared with biodiesel pilot mode,Pode mode has better economy.
