摘要
阐述了循环变动对汽油机的动力性、经济性及排放的不利影响 ,进而研究其影响因素。用实测的汽油机相继若干循环的示功图 ,对用缸内压力参数表征循环变动的适应性作出评价。
Cyclical Combustion Variation (CCV) deteriorates the power, economic and exhaust performance of gasoline engine.It is of great importance and practical significance to measure CCV for the sake of optimizing gasoline engine behavior. Based on a number of continuous pressure indicator diagrams in cylinder,the adaptation of cylinder pressure parameters used to assess CCV is mainly analyzed in this paper.
