摘要
基于不同地区不同天然气组分的变化情况,对不同组分的天然气的C/H比、燃料低热值、理论空燃比进行计算与研究。运用GT-power软件建模方式,建立发动机准维燃烧模型,对不同组分的天然气进行燃烧过程分析,以便掌握发动机CO,NO等排放参数及动力性能变化规律,为研制燃烧不同组分天然气的发动机控制算法奠定基础。
Based on the changes of natural gas composition in different area, in this paper, the natural gas C/H ratio, fuel calorific value and theoretical air-fuel ratio are calculated for different compositions of natural gas. The quasi-combustion engine dimensional model is built with the GT-power software. The combustion procedures of different gas compositions are analyzed. The emissions of CO, NO, etc. and the dynamic performance of engine are obtained. The work is laying foundations of natural gas engine control algorithm.
