  1. The hydraulically actuating, electronically controlled variable valve actuator, the common rail hydraulical source and the electronic control unit have been designed and developed. the primary control strategies of the valve timing in different conditions have been discussed. the performance of the system has been researched deeply by experiments, from which, plenty of rules have been obtained, and the way to adjust valve timing, lift and duration has been put forward

    研製了電控可變氣門系統的執行器? ?電控可變氣門驅動機構，設計了電控可變氣門系統的液壓驅動源? ?中壓共軌液壓源，開發了電控可變氣門系統的電子控制單元，實現了在不同工況下，氣門正時、氣門開啟持續期、氣門升程柔性的電子控制，並對不同工況下配氣正時的控制策略進行了初步探討。
  2. Firstly, the potential of optimizing the performances of the diesel engine by variable valve timing, duration, and lift has been investigated. and the haecvvs is developed

    論文首先分析了配氣參數調節對發動機性能優化的潛力，然後針對135型柴油機開發了一套中壓共軌電控可變氣門系統。
  3. Consequently, to optimize the engine performance in any condition and any circumstances, a need exists for a device that permits variable valve timing, variable lift and variable valve duration during engine operation. so a flexible, hydraulically actuating, electronically controlled variable valve system ( haecvvs ) for model 2135 diesel engine and the experiment bench for its performance have been deve loped

    為了能夠在任意工況下對發動機的性能進行優化，作者在系統分析了國內外各種可變氣門系統的發展狀況及特點的基礎上，開發了一套中壓共軌、液壓驅動、電子控制可變氣門系統及其性能測試臺架，並對電控可變氣門系統的性能進行了研究。
