基于GT-Power的柴油机环境适应性研究

Research on the Adaptability to Variable Environments of Diesel Engine Based on GT-Power

分析了大气温度和压力变化对柴油机性能的影响；采用GT-Power软件对柴油机缸内工作过程进行模拟计算，并通过柴油机台架试验对仿真模型进行校核；经计算得到：随着大气温度的升高，缸内最高爆发压力和柴油机功率降低，燃油消耗率升高；随着大气压力的升高，缸内最高爆发压力和功率增大，燃油消耗率降低。研究结果可为研究柴油机对复杂环境的适应性提供参考依据。

This article introduces the effects that the variable natural environments have on the performance of the diesel engine. GT-Power software is used to simulate the working process of the diesel engine, and the simulated model is checked through the diesel engine bench test. With the increasing atmospheric temperature, the highest pressure of cylinder and the diesel engine power decrease, the fuel-consumption rate of the diesel engine increases. With the increasing atmospheric pressure, the highest pressure of cylinder and the diesel engine power increase, and the fuel-consumption rate of the diesel engine decreases. This research provides the reference basis for studying the adaptability of the diesel engine to complex environments.
