摘要
基于全可变气门运动机构的气门参数控制燃烧技术是改善传统SI汽油机燃油经济性,提高动力性和降低排放的最为有效的途径之一。但是这也对发动机进气量的测量和控制提出了更高的要求。本文通过仿真和试验相结合的方法,对基于全可变气门机构汽油机进气量测量和控制问题进行了探讨和研究。
Variable valve technology is one of the most applicable measures to improving fuel economy, power performance and emissions of conventional SI engines. But this technology also has poised a higher demand for measurement and control strategies of engine mass air flow. This paper investigated on the accurate measurement of the intake mass and the control strategy for a Gasoline Engine which equipped with fully variable valve systems and this engine has been taken out the throttle body. This paper use both of the simulation and experiment method is introduced in this research, the eigenvalue of the waveform from the hot film flowmeter which is effected by the pulsant airflow has been analyzed.
