【摘要】 研究了在4102型废气涡轮增压柴油发动机上采用柴油/甲醇组合燃烧方式后对发动机各种排放的影响。试验结果表明,在比油耗降低的同时,碳烟、NOx 和CO2 的排放量也得到减少;虽然HC和CO排放有所升高,但是由于排气温度始终高于400 ℃,可以通过催化转换器将其转化。更多还原

【Abstract】 The exhaust emissions of a turbo-charged direct injection diesel engine with diesel/methanol compound combustion were studied. The results showed that Smoke, NO_x and CO₂ could be decreased along with the improvement of fuel economy with slight increase in HC and CO, however, the high exhaust temperature （over 400 ℃） will be beneficial to utilization of catalytic converter for emission further reduction.更多还原
