Abstract


The results presented in this study are related to the distributions of temperature in the various components of an internal combustion engine. We are interested in the heat transfer processes in the various components of the engine (cylinder head, piston, cylinder liner and valve). In order to appreciate the influence of some parameters on heat transfer in this engine, a sensitivity study to some parameters of the problem is done. This sensitivity study approach is related to the influence of the length of the cylinder liner, the fined surface and the fined spacing. To solve partial non linear differential equations given by the mathematical modelling of these phenomena, an algorithm proposed by PATANKAR is used. Obtained results are compared to those obtained by others. A good agreement is observed between the various results.
