车用柴油机瞬态工况试验及性能评价方法
Experiment and performance evaluation methods for automotive diesel engines under transient operation conditions
摘要
Abstract
In order to conveniently study and accurately evaluate engine performance under transient operation con-ditions, the European Transient Cycle (ETC)was analyzed and it was determined that operational conditions of con-stant rotation speed and increasing torque might be taken as the typical transient operation conditions of an engine. Simultaneously, a test analysis was carried out for the conditions of constant rotation speed and the loading process at different transient times, and the following parameters were proposed:the"lag coefficient", which is an evalua-tion index for the degree of delay of the performance parameters of an engine in the transient process;the"deterio-ration coefficient" ,which is an evaluation index for the worsening degrees of the transient performance of an en-gine;the"transient total" and"transient average", which are the indices for evaluating the comprehensive transi-ent performances of an engine. The experimental results show that the above-mentioned evaluation methods may e-valuate the performances of an engine clearly and comprehensively throughout the entire transient process. As far as the entire loading process is concerned, the loading speed, gross fuel consumption and NOx emissions have an ap-parent compromised relation with the gross emissions of soot and CO.关键词
