Estimation of Heat Transfer Rate to Coolant from Combustion Chamber of Liquid Cooled IC Engine

Heat transfer analysis in the combustion chamber of internal combustion engine is crucial to design the combustion chamber. Manufactures will always look for the durability, better engine performance and also on the material cost for designing the combustion chamber. This will be achieved by designing the efficient combustion chamber effectively. The purpose of this paper is to determine the Adiabatic Flame Temperature using stoichiometric equations and find the gas temperatures at different points in the ideal diesel cycle. These values are used in the existed heat transfer coefficient equations and estimate the heat transfer to the coolant through the cylinder wall using one dimensional heat equation. This theoretical value of heat transfer rate is compared with the experimental heat transfer rate of the three cylinder engine. The average error percentage of the theoretical and experimental values is less than the 15 %.
