摘要
提出了一种压缩空气/燃油混合动力发动机概念,该发动机可以在压缩空气动力和内燃机两种模式下运行。运用理想热力循环理论建立了混合动力发动机两种工作模式的数学模型,并对平均指示压力及其他重要性能指标进行了仿真研究。仿真结果表明,两种工作模式下发动机的平均指示压力等主要性能指标与传统内燃机相近,而且能够实现两种工作模式的平稳切换,这说明压缩空气/燃油混合动力发动机是可行的,并能够达到节约燃油、减少尾气污染排放的目的。
A new hybrid compressed--air and fuel engine concept was proposed, which can work by both compressed--air powered engine mode and internal combustion engine mode. The new hybrid engine was modeled using ideal thermodynamics cycles, and the simulation analysis was made in the indicated mean pressure as well as other performance parameters. The simulation results show that the indicated mean pressure and other important performance parameters are approximate to those of the traditional internal combustion engine, and switch between the two engine modes is smooth. Results show the feasibility of the new hybrid compressed--air and fuel engine concept in achieving fuel economy and emission reduction
