A mathematical simulation model was developed to calculate the internal and the external temperature of a motor compartment wall with radiant heat exchange of the exhaust system and with convective heat exchange with the compartment inside air. Fields experiments were conducted to evaluate the model with a road bus and a heavy truck. Precision less than 5% was gotten between experimental measurements and model results. The effectiveness of the heat shield was verified numerical and experimentally on a heavy truck.
