摘要
开展了柴油机燃用柴油/二甲氧基甲烷混合燃料的性能与排放研究。研究结果表明,随着燃料中二甲氧基甲烷掺混比例的增加,有效燃油消耗率有所增加,但折算成当量柴油的有效燃油消耗率降低,有效热效率增加。在同一工况下,发动机排气碳烟随二甲氧基甲烷的加入而降低,NOx则无明显的上升;CO排放也随着二甲氧基甲烷的增加而降低。
In this paper, the performance and emissions of a direct injection diesel engine operating on the diesel/dimethoxymethane blends were investigated. The results show that the brake specific fuel consumption (b.s.f.c.) is increased while the diesel equivalent brake specific fuel consumption is decreased and the thermal efficiency will increase with the increase of dimethoxymethane (DMM) fraction in the blends. For the same brake mean effective pressure (bmep), the exhaust smoke and CO decrease with the increase of DMM fraction in the blends while NO_x shows little variation with the addition of DMM in diesel fuel.
