高原环境非增压LNG汽车发动机模拟仿真与试验

Simulation and Experiment of LNG Non- supercharged Engine under Plateau Environment

采用GT-power软件对高原环境非增压LNG汽车发动机进行模拟仿真,并与该机的外特性试验数据进行对比分析。结果表明,该模型下获得的功率和转矩误差较低,比气耗误差值在合理范围,GT-power模拟仿真准确可靠。

Through the GT - power to the simulation modeling of non booster LNG engine, analysis and comparison with external characteristic of original machine, the error value of power and torque is lower , the reduced error value of gas consumption is in reasonable scope with original machine, so the GT - power model simulation is accurate and reliable.
