| 摘 要： | 为改善车用发动机部分负载时的燃油经济性,提出了一种应用电磁驱动气门来实现的发动机停缸技术.首先对发动机某一气缸停止工作循环时的工作过程进行了性能仿真,以单缸在1个循环内所做负功最小为优化目标,计算得到了单缸停止1个工作循环的起始点.以尽量保证各缸间的工作均匀性为基本原则,设计了4缸发动机顺序间歇停缸方案并进行了仿真与分...

| Abstract: | To improve the fuel economy of vehicle engine at part load,a technology of cylinder deactivation based on the electromagnetic valve actuation was put forward.The one-cycle working process of deactivating a cylinder was simulated.Aiming at the least negative power of single cylinder in one cycle,the starting point of cylinder deactivation was acquired.Based on the working uniformity between cylinders,the control scheme of sequential intermittent cylinder deactivation for 4-cylinder engine was formulated and ... |
