150柴油机燃烧过程的模型分析和评价

Model Analyses and Evaluation For Combustion Process of 150 Diesel Engine

本文首先介绍了新开发的时序多区准维燃烧模型的主要特点和构成,以及为分析150柴油机燃烧过程而对模型所作的标定和验证,文章接着根据模型的计算结果分析了该柴油机燃烧系统的燃烧特点,并对设计的合理性以及今后改进的方向等给予了评价。

In this paper, the main feature and structure of a newly developed quasi-dimensional combustion model—Time Sequencing Multi-zone Model are described.Also, the calibration and validation of the model made for analyses of 150 diesel engine combustion process are indicated.According to the results of model calculations, the combustion characteristics of the engines combustion system are analysed.Comments on design merits, further improvements, etc.are made at the end of the paper.
