摘要
针对某装甲车辆动力系统,基于实车进/排气状态、热负荷及使用工况测试,分析了其高原环境适应性。试验结果表明,发动机与涡轮增压匹配向低转速区偏移,将有利于加速和起步时的进气补偿;热负荷制约了车辆的挡位,导致车辆平均速度降低;排气温度应作为监测及控制的关键参数。
According to the vehicle intake and exhaust conditions, the thermal load and the operating condition test, the plateau environmental adaptability of armored vehicle power system was analyzed. The test result shows that, moving the matching of engine and turbocharger to the low speed area would be beneficial to the intake air compensation at the vehicle acceleration and start; Thermal load would restrict vehicle gear shifting, resulting in the reduction of vehicle average speed; Moreover, exhaust temperature
