介绍了用有限元法计算内燃机燃烧室壁面周期性温度波动的原理及程序设计。并用此程序采用一维传热模型对２８５ＱＢ油冷柴油机缸盖燃烧室壁面周期性温度波进行了计算，计算结果符合规律，用该方法可以按二维、三维传热模型计算内燃机燃烧室壁面周期性温度波动。
The principle and program design of calculating the periodic temperature fluctuation in the combustion chamber wall of a combustion engine by using the finite element method are introduced. In this program, the one-dimensional heat transfer model was used to calculate the periodic temperature wave in the combustion chamber wall of the 285QB oil-cooled diesel engine. The calculation results accord with the law. By this method, the combustion chamber wall period Sexual temperature fluctuations.
