摘　　要：针对某直列六缸增压中冷柴油机,在标准试验条件下通过台架试验进行了一级增压和二级增压对柴油机性能影响研究,分析了二级增压对柴油机各性能指标影响。同时,在原机基础上进行了性能改善的研究。研究结果表明:二级增压可提高柴油机有效热效率,减小柴油机的燃油消耗率,降低碳烟排放,进一步提高柴油机动力性能。通过适当调整供油提前角,在对其他性能指标影响较小的前提下,降低缸内最高燃烧压力。The single-stage and two-stage turbocharging test were carried out under standard ambient conditions on a test bed with a tubocharged and charge-cooled inline 6-cylinder diesel engine. The influence of two-stage turboeharging on engine related parameters was analyzed. In addition, the performance improvement was researched based on the original engine. The results show that two-stage turbocharging can improve the effective thermal efficiency and reduce the fuel consumption and soot emission. Changing fuel supply advance angle will decrease the maximum combustion pressure under the premise of less influence on other performance parameters.
