摘　　要：为了研究柴油品质对柴油机的影响,采用国Ⅲ、国Ⅳ标准柴油和京Ⅴ标准柴油,在JX493ZLQ3柴油机上进行负荷特性试验,设定工况2000r/min,油门开度为20%、35%、50%、65%、80%、90%和95%,比较和分析了燃用3种柴油时柴油机的经济性和排放特性。结果表明,在柴油机不做任何改动的条件下,柴油品质对柴油机燃油经济性有影响;对CO和HC排放的影响不明显;对NOx和PM排放影响较为明显,其中,国Ⅲ柴油排放相对较高。In order to study the effect of diesel fuel quality on a diesel engine, China Ⅲ diesel, China Ⅳ diesel and Beijing V diesel were used, and the load-performance tests were carried out on a JX493ZLQ3 diesel engine. The revolution was set at 2 000 r/min, and the throttle opening was set at 20%, 35%, 50%, 65%, 80%, 90% and 95%, respectively. The effect of diesel fuel quality on fuel economy and emission characteristics of the diesel engine were compared and analyzed. The results showed that without any changes to the engine, diesel fuel quality could influence the fuel economy. The effect on CO and HC emissions was not obvious. Diesel fuel quality had obvious effect on NO, and PM emissions, and China Ⅲ diesel caused relatively high emissions.
