摘　　要：研究了一种大功率中速柴油机在高海拔地区性能参数发生的变化,并通过对原型机的功率修正,机油泵、燃油泵、动力组和增压器等方面的高原适应性改进和优化,使该款柴油机在高原地区具有良好性能,满足高海拔地区运用的过渡型高原内燃机车牵引动力的需求。Performance parameters variation ol a medium-speed high-power diesel engine run in high altitude area was analyzed in this paper. The engine ol this type showed good performance in the plateau,which met demand ol traction power ol transition diesel locomotive lor plateau applica-tion. Based on power correction ol the original engine,the plateau adaptability was improved by opti-mizing the oil pump,fuel pump,power assembly and turbocharger etc.
