多缸柴油机冷起动过程的模型研究

An Investigation on the Cold Starting Model for Multi Cylinder Diesel Engines

为了研究多缸柴油机冷起动瞬态过程的特点和影响因素，在原有的包括准维燃烧模型的单缸直喷式柴油机冷起动过程预测模型基础上，分析多缸机冷起动过程特点，建立了多缸直喷式柴油机冷起动过程的瞬态模型，在详细分析多缸柴油机冷起动特点的基础上，介绍了冷起动模型的主要构成和计算公式．

In order to study the transient performance of and affecting factors on the cold starting process of multi cylinder diesel engines, a cold starting model is developed on the basis of the existing prediction nodel for single cylinder diesel engines and the quasi dimensional combustion model. The specific features of the cold starting process of multi cylinder diesel engines are analyzed and hte main components and calculating formulae for the model are given.
