直喷式柴油机准维燃烧模型的改进和应用

本文叙述了作者对直喷式柴油机准维燃烧模型的改进。由改进模型发展了一个独立的单缸循环模拟软件,并对缸径为110mm 的直喷式柴油机进行了参数分析。通过与实测对照,证实了模型的实用性,也揭示出某些不足,而这正是要进一步完善的关键所在。

Improvements and Applications of D.I.Diesel Engine Quasi-dimensional Combustion Model

The improvements of D.I.Diesel engine quasi-dimensional combus- tion model are described in this paper.Based on this improved model,a self-con- tained software for single cylinder engine cycle simulation is developed and then applied to parameter analysis for a D.I.diesel engine with 110 mm in bore dia- meter.Comparison between calculation and experiment results makes sure the prac- ticability of the model,and also reveals some deficiency in the model which is the key to further perfection.
