摘要

本研究的主要目的是利用GT Suite软件开发一个发动机循环模拟程序，分析当量比和压缩比对四冲程直喷火花点火式发动机主要排放的影响。实验结果用于将所获得的气缸压力结果与所开发的模型进行比较。本文采用两区燃烧分析模型，利用GT Suite仿真软件，研究了压缩比和当量比对直喷火花发动机主要排放的影响。利用实验数据对所建立的分析模型进行了验证。通过实验验证了燃烧室中压力的分析曲线，其差值约为6%。

Numerical Modelling of Emission Characteristic for a Single Cylinder Spark Ignition Engine

The main objective of this study is to elaborate an engine cycle simulation program using GT-Suite software to analyze the influence of equivalence ration and compression ratio on the main emissions of a four-stroke direct injection spark ignition engine. The experimental result is used to compare the cylinder pressure result obtained with the developed model. The present article is a study of the effect of compression ratio and equivalence ratio on the main emissions of the direct injection spark engine for a two-zone combustion analytical model and by using of the GT-Suite simulation software. The developed analytical model is validated by the use of experimental data. The analytical curve of the pressure in the combustion chamber is experimentally validated with a difference of the order of 6%.
