Many researches have been done with the simulation model . it was found that some structure parameters such as the diameter of the driving piston , the diameter of the buffer piston , the stiffness of the valve spring , the compress ratio of the buffer piston , and the flux area of the solenoid valve etc . have great effect on the performance of the haecvvs . for certain performance demand of the variable vale system , there is a most suitable combination for the structure parameters 通過對(duì)電控可變氣門系統(tǒng)的主要結(jié)構(gòu)參數(shù),如動(dòng)力活塞直徑、緩沖活塞直徑、氣門彈簧剛度、緩沖活塞實(shí)際壓縮比、電磁閥通流面積等參中壓共軌電控柴油機(jī)可變氣門系統(tǒng)的研究數(shù)對(duì)電控可變氣門系統(tǒng)啟、閉特性的影響規(guī)律的研究發(fā)現(xiàn),動(dòng)力活塞直徑、氣門彈簧剛度、電磁閥通流面積對(duì)電控可變氣門系統(tǒng)啟、閉性能起著決定性的作用,對(duì)于一定的氣門啟閉規(guī)律要求,這些結(jié)構(gòu)參數(shù)存在一組最佳值。
