煤制乙醇在柴油机上的高效清洁利用研究
Research on the efficient and clean use of coal-derived ethanol in diesel Engines
为了有效降低传统燃用燃料在发动机上的排放，缓解能源短缺问题。在分析了煤制乙醇理化性质的基础上，设计优化了柴油机使用煤制乙醇时的部分参数选择，对发动机掺烧乙醇后的动力性能、经济性能以及废气排放等方面进行了研究。研究结果表明:柴油机上掺烧20%的煤制乙醇时，其动力性与排放性得到最佳改善，在掺烧25%的煤制乙醇时当量燃油消耗率下降最明显。
In order to effectively reduce the exhaust emissions of traditional combustion fuels on the engine and alleviate the problem of energy shortage. On the basis of analyzing the physical and chemical properties of coal derived ethanol, the design optimizes some parameter selection when using coal derived ethanol in the diesel engine, and studies the dynamic performance, economic performance and emissions of the engine with ethanol, and the research results show that when 20% coal derived ethanol is mixed on the diesel engine, its power and emission performance are best improved, and the equivalent fuel consumption rate decreases most significantly when 25% coal derived ethanol is blended.
