    摘要:

    汽油機電液式可變氣門正時系統(tǒng)(VVT)的響應性能對發(fā)動機燃燒,、排放均有重要影響,汽油機瞬態(tài)過程中電液式VVT應根據(jù)發(fā)動機工況快速調整到目標相位,，但由于電液VVT的響應性能受到多方面因素的影響,，其速度尚有進一步提升的空間,?；谠囼灪头抡娣治?，對影響電液VVT響應性能的發(fā)動機轉速、機油溫度,、機油壓力等因素進行了分析,，并詳細分析了VVT階躍響應過程各階段的影響因素，提出了基于MAP查表的VVT前饋控制算法,，試驗結果表明,，該算法能夠實現(xiàn)VVT快速響應，同時保證穩(wěn)定性,。

    Abstract:

    The response performance of electr-hydraulic VVT technology has significant influence on combustion and emission of gasoline engine. Actual valve timing value should be quickly adjusted to target value on transient operation conditions for gasoline engine. Response speed of electro-hydraulic VVT can be further improved since it has constraints for breakthrough. Factors which have influence on the response speed of electr-hydraulic VVT were studied by both experiment and simulation. Step response process was divided into several sub-process and analyzed. Feed forward control algorithm was designed and applied in VVT control. Experiment results showed that the proposed method could achieve rapid response of VVT and assure the stability at the same time.
