| 摘 要： | 针对中小排量摩托车发动机的特点，研制了可切换双进气正时参数VVT系统．以一维CFD计算为基础，建立了摩托车发动机VVT系统的循环仿真模型。在此基础上，对发动机怠速低负荷、中等负荷、低转速高负荷、高转速高负荷不同工况条件下VVTL（Variable Valve Timing and Lifting）运行模式的控制策略进行了详细探讨．结合JH125摩托车发动机所进行的研究表明，VVT系统可以在各种不同工况下实现发动机动力性、经济性以及排放性能的有效提高．

| Abstract: | An original variable valve timing mechanism with two-mode intake timing parameters is developed according to the structural characteristics of small-medium displacement motorcycle engine. Based on cycle simulation, a cycle simulation model of VVT mechanism for motorcycle engine is created. The control strategy of variable valve timing and lifting running-model are carried out at idle speed low negative load, middle negative load, low speed high negative load and high speed high negative load. It has been proved that the performance of JH125 motorcycle engine can be effectively improved by loading the new type VVT system. |
