摘　　要：在直喷柴油机上掺烧低比例二甲醚(DME)和高比例柴油二元混合燃料进行试验研究,除低压供油系统进行技术改造外,原柴油机的结构和参数不做任何改变。试验结果表明:掺烧30%二甲醚与70%柴油二元混合燃料,不采取任何尾气处理措施,碳烟排放比原柴油机降低67%,NOx排放与原柴油机相当,燃油消耗率比原柴油机降低19.3%;直喷柴油机掺烧低比例二甲醚和高比例柴油二元混合燃料在降低碳烟和燃油消耗率方面的优越性能。The paper presented the research results of a direct injection diesel engine operation on a blend of low proportion dimethyl ether （DME） and high proportion diesel. Except the low- pressure part of fuel supply system, the structure and parameter of the archetypal one were not modified. The experiment shows that fuelled with 30% DME and 70% diesel without exhaust disposal, the gas carbon emission decreases by 67% and fuel consumption decreases by 19.3% than those of the archetypal one; the superiority of the direct injection diesel engine fuelled this blend in the smoke and fuel consumption.
