电动涡轮增压汽油机性能研究

Study on the Performance of Electric Turbocharged Gasoline Engine

采用仿真与实验研究相结合的手段,从动力性和经济性等方面研究了电动涡轮增压对汽油机性能的影响。通过非增压汽油机GT-POWER仿真模型的模拟结果与相同条件下的台架试验数据进行对比,验证了仿真模型的合理性,并在非增压模型的基础上建立电动涡轮增压仿真模型。增压与非增压仿真模拟结果对比分析表明:相同工况下,电动涡轮增压能够较好的改善汽油机的动力性和经济性。

The performance of an electric turbocharged gasoline engine was studied in the terms of powerful and economical perspectives by employing the combination of simulation and experimental study in this paper.The simulation results of the GT-POWER simulation model of non-supercharged engine was compared to the bench tested results under the same condition.The rationality of the simulation model was verified and the electric turbo simulation model was established based on the non-supercharged simulation model.The results showed that the electric turbo can better improve engine performance and fuel economy under the same working condition.
