Engine head is one of the most complicated parts of internal combustion engine. It is directly exposed to high combustion pressure and temperature. In this paper, engine head heat transfer rate for 70.4 kW diesel engine. The design engine head is made of gray cast iron alloy. The original engine head is made of aluminums alloy. The cast iron engine head can get over heat temperature because the thermal conductivity of cast iron is not as good as aluminium. So that it is necessary of increasing the cooling efficiency. In the engine heat transfer calculation, the heat fluxes from the engine head are calculated with vary engine speeds and water velocity and heat transfer analysis is required for the engine metal changing process.
