摘要
为研究甲醇裂解气-柴油混合燃料对柴油机排放的影响,设计了一种集成式尾气裂解甲醇反应器和进气共轨系统,将YC6A220型柴油机改装成燃烧由甲醇裂解而成的氢富气与柴油混合燃料的柴油机。实验研究表明,改装后的柴油机在中、高负荷运行时可以使NOx、HC和碳烟大幅度降低,且随着甲醇裂解气掺烧量的增加,各排放物质的减少量增加。
To study the impact of methanol cracking gas-diesel blended fuel on diesel engine emission,the paper designs an integrated exhaust-based methanol cracking reactor and intake common rail system,and refits the YC6A220 type diesel engine into diesel engine with mixed fuel of diesel and hydrogen-rich gas from methanol cracking.The experimental study shows that the converted diesel engine enables significant reduction in NOx,HC and soot when operating under middle and high loads,and the emissions of various substances reduce as the additional combustion amount of methanol cracking gas increases.
