Finite element heat transfer analysis of the cylinder head of a SI engine


Heat transfer is a crucial phenomenon in the internal combustion engine. For efficient working of the engine, heat transfer should be optimized such that there are no high temperature developed in the engine and also pressure inside the cylinder shouldn’t fall below a certain critical value which may result in the loss of work. A Finite Element model of cylinder head was analyzed for temperature and stresses by subjecting it to running engine conditions. The thermal analysis was performed by applying a constant thermal load for 60 sec. The thermal analysis was followed by structural analysis which is performed using the results of thermal analysis as load. The model was then tested for the different fin thickness. The temperature variation was observed for 2mm, 2.5mm, 3mm and 3.5mm thickness for all the three materials. It was observed that for 3mm thickness highest heat transfer occurred and therefore low temperatures were obtained.
