摘　　要：由于具有较高的十六烷值,相对简单的化学结构、无碳烟排放以及易于与运送的特点,二甲醚被公认是最有发展潜力的柴油机代用燃料之一。而重油作为海洋运输中最主要的燃料,燃油品质低劣。在此项研究中,我们通过试验,在一台直燃式柴油机上燃用二甲醚和重油混合燃料,观察并测量排放情况。结果发现:二甲醚和重油复合燃料是一种有效的清洁代用燃料,能有效降低柴油机废弃物CO、HC和烟度的排放。DME（Dimethyl ether） is regarded as one of the candidates of alternative fuels for diesel engine,because of its higher cetane number suitable for a compression ignition engine.Also,DME is a simple chemical structure,colorless gas that is easily liquefied and transported.On the other hand,Bunker oil has long been used as a basic fuel in marine diesel engines and is the lowest grade fuel oil.In this study,the combustion and emission characteristics were measured experimentally in the direct injection type diesel engine operated with DME and Heavy oil mixed fuel.From our experimental results,it is induced that DME and Heavy oil blended fuel would be an effective fuel which can reduces the concentration of harmful matter in exhaust gases.
