Resumo

The internal combustion engine is a complex engineering system with rich heat transfer applications. It is the purpose of the present work to illustrate the methodology used to link an engine combustion predictive computational program with both a cooling system simulation and a metallic temperature predictor models. By using a combustion engine predictive tool, the heat flow rates dissipated through the combustion chamber walls of an engine operating under city driving conditions are obtained. This information is used in the modelling and simulation studies of the engine cooling system design. The Amesim cooling system model is built and the temperatures obtained after the simulation are fed to a computational program that calculates the temperatures of the engine metallic parts. Results of the simulation are evaluated by comparison with the experimental behaviour of an analogous engine.
