摘要
为了避免两用燃料发动机在由纯汽油工况向纯天然气工况切换过程中出现转速大幅度波动现象,实现油气切换过程平稳过渡,达到优化控制的目的,分析了油气切换过程中引起转速大幅度波动的原因,建立了油气切换过程优化控制模型.仿真结果表明:该模型有效,具有实用性.
The cause of the speed fluctuation of a compressed natural gas （CNG） /diesel dual fuel engine in the period of fuel switching from pure gasoline to CNG is analyzed, and an optimal control model for fuel switching is set up based on variation method. The results of simulation show that the model is effective and practicable. The speed fluctuation is eliminated, a smooth transition in the period of fuel switching is realized, a better fuel economy is obtained and the goal of optimal control is achieved.
