两冲程HCCI自由活塞式内燃发电机仿真（Simulation of Two Stroke HCCI Free Piston Linear Alternator）
发电机 自由活塞 Matlab/Simulink Chemkin
2009/5/22
综合利用Matlab/Simulink、Chemkin、电磁场有限元法对HCCI自由活塞式内燃发电机建立了仿真模型。分析了系统的运动特征，阐明了它与传统内燃机运动规律的差异。讨论了变负荷、燃空当量比下自由活塞式内燃机的变压缩比特性。仿真结果表明，自由活塞式内燃发电机能够根据外部参数调节压缩比，当工作在高压缩比下时，有利于提高燃烧效率、降低内燃机排放。
