线性调节乙醇体积分数对柴油机排放物的影响

Linear Regulation Ethanol Volume of Conventional Diesel Engine Emissions Impact

针对目前日益加剧的能源危机和环境污染,在单缸柴油机上设计了线性调节掺醇比供油系统,同时采用对比试验方法,研究了乙醇体积分数在E0-E30范围内发动机常规排放物的变化情况。结果表明,线性调节供油系统满足试验要求,碳烟排放和NOx排放降低,HC和CO的排放增加,为进一步推广醇类燃料在柴油机上的应用提供了一定的参考依据。

In light of growing energy crisis and environmental pollution, in a single - cylinder diesel engine, the design of the linear regulator alcohol - doped than oil supply system, while comparative test methods used to study the alcohol concentration in the E0 - E30 within the framework of conventional engines Emissions from the emissions changes. The results showed that the linear - conditioning system to meet the test requirements of oil, soot emissions and lower NOx emissions, HC and CO emissions to increase for the further promotion of alcohol in diesel fuel on the application of a certain reference.
