研究涡流室式柴油机燃烧过程的新方法

A New Method for Analyzing Combustion Process on Swirl Chamber Diesel Engines

本文作者在ＳＤ１９５（Ｄ×Ｓ＝９５ｍｍ×１１５ｍｍ）、ＳＤ２１００（Ｄ×Ｓ＝１００ｍｍ×１１５ｍｍ）２种涡流室式柴油机上进行了有关涡流室结构参数及燃烧过程的研究，提出了以４段累积放热率来评价涡流室燃烧系统燃烧过程及其结构参数的新方法。结果表明应用该方法较总放热率分析法简单且准确。

Swirl chamber structure parameters are investigated on SD195( D×S =95 mm×115 mm)and SD2100( D×S =100 mm×115 mm) diesel engines.A new method which is named 4 stages accumulative heat release rate is developed.With this method,it is easy to analyze the combustion process and swirl chamber construction parameters.
