Development of a Method for Predicting Heat Rejection to the Engine Coolant 931114

The higher output levels attained by recent automotive engines have been accompanied with an increase in the amount of heat generated by the engine. This higher heat release level, together with the styling trend toward a lower hood line, requires a method for accurately predicting heat release to the engine coolant. In this research, the heat flow path in the engine was separated into several components and equations were formulated for estimating the amount of heat released by each component. The whole heat release to the engine coolant was obtained by totaling the heat release of each component.
