一种适用于柴油机控制的缸内子模型

A Kind of Cylinder Model Used for Diesel Engine Control

本文较详细地介绍了一种可用于柴油机控制的缸内子模型。应用能量、质量守恒定律和气体状态方程推出压缩阶段、膨胀阶段和换气阶段的数学模型。由于柴油机的滞燃期、燃烧阶段是一个复杂的过程，因此本文提出了一种比较简单的模型，以简化计算，适应控制模型的要求。实验结果和计算结果取得了比较好的吻合。

This paper introduces a kind of cylindric model which is able to be used in the diesel engine controlled model. The mathematical model which describe compression, inflation, and changing air is deduced by applying energetic conservation theory, mass conservation theory and gas state equa- tion. Because the diesel engine's ignition delay and combustion are a complex process, this paper propose a simpler model to simplify calculation and to meet the requirement of the controlled model. The agreement between experimental and theoretical results is satisfactory.
