X195型柴油机代用燃料的试验研究

结合X195型柴油机结构特点，在不改变原机结构的前提下，增设一套乙醇供给系统，进行柴油机代用燃料试验。发动机工作时乙醇喷射器适时向气缸内喷射适量乙醇，并与柴油混合燃烧。试验结果表明，增设的乙醇供给系统工作性能可靠，双燃料燃烧时，减少柴油达11．7％，烟度下降32％。

Experimental Research of Alternative Fuel for X195 Diesel Engine

Based on the construction features of a X195 diesel engine, a set of ethanol supply system was added on it without constructional modification of the former engine. When the engine operates , the nozzle will inject a certain amount of ethanol into cylinder. The ethanol will be mixed and burned together with the diesel injected by diesel injector to reduce the consumption of diesel and emissions. The experimental results showed that this ethanol system was satisfactory on operating characteristics and specific fuel consumption and the exhaust smoke density was considerably reduced to achieve the purpose of fuel saving and emission reducing. Meanwhile, the theory basis were available for further study.
