摘要
提出了一种根据燃烧分析仪测录的示功图计算 LPG-柴油双燃料发动机燃烧放热规律的新模型 .简要介绍了该模型的计算原理和方法 .利用该模型分别计算了 LPG-柴油双燃料发动机的引燃柴油、LPG及总的燃烧放热率 ,分析了其燃烧过程及燃烧特性 ,并与试验结果进行了分析比较 。
A new model was brought forward to calculate the heat release rate curves of a diesel LPG dual fuel engine on the basis of indicator diagrams measured by a combustion analyzer. The principle of this model is briefly introduced. The heat release rate curves of pilot diesel,LPG and diesel LPG are calculated with the new model. The combustion processes and the combustion characteristics of a diesel LPG dual fuel engine are studied. The results of the calculations are analyzed and compared with the test results. It provides a convenient and efficient way for studying combustion characteristics of the dual fuel engine.
