The quest for increasing the efficiency of an internal combustion engine has been going on ever since the invention of this reliable work equipment. In recent times much attention has been focused on achieving higher thermal efficiency by reducing the heat loss to the surroundings by the application of “low heat rejection” concept using ceramic coating for engine components or ceramic components itself. In this direction, the present analysis focused on the formulation and development of a two zone combustion model for the prediction of combustion, heat release and performance of the conventionally Water cooled and low heat rejection engines. The low heat rejection concept is introduced in this model by developing and formulating a wall heat transfer model to consider the effect of instantaneous inside surface temperature on combustion and heat release of an LHR engine. The gas wall heat transfer by means of convection and radiation is calculated using various gas wall heat transfer models. The predictions by the computer model and experimental findings are demonstrated. The capability of this model and the comparison of the predicted results with experimental findings are highly satisfactory.
