汽油机过渡工况进气测量的研究

发动机在过渡工况中，进气系统存在着动态的充排气现象，此时基于静态标定数据的查表法得到的结果并不代表实际的缸内进气流量。通过对过渡工况进气测量的研究，总结了过渡工况的进气特性，并设计了基于状态反馈的进气流量估值器，解决了过渡工况缸内进气流量的测量问题。

Dynamic induction and exhaust phenomena are existing in the engine induction system under engine transitional working mode, so numerical data obtained by checking the data table which has been statically calibrated can not represent the practical engine cylinder induction air flow. Air induction characteristic in transitional working made is summarized through research work of induction air transitional working made measurement and induction air flow estimator based on status back feed is then designed. Thus, the problem of engine cyclinder induction air flow measurement under transitional working made is solved.
