涡轮增压柴油机高海拔(低气压)性能试验研究

An Experimental Study on Performance of Turbocharged Diesel Engines at High Altitude (Low Air Pressure)

在内燃机高海拔(低气压)模拟试验台上,对不同模拟海拔高度下的涡轮增压柴油机性能进行了试验研究。分析了海拔高度的变化对涡轮增压柴油机动力性、经济性的影响,研究了涡轮增压柴油机最大转矩、最低燃油消耗率随海拔高度的变化规律,为进一步提高高海拔地区涡轮增压柴油机的性能提供了重要的理论依据。

The performance of turbocharged diesel engines at different high altitudes was studied on the engine test bed for simulating high altitude (low air pressure). The effects of altitude on engine performance of power and fuel consumption were analyzed in detail. The variation of maximum engine torque and minimum fuel consumption with altitude were studied by numericalmethod. The results can provide important guidance for increasing performance of turbocharged diesel engines at plateau.
