Abstract
A computer code named ESTAP (Exhaust System Thermal Analysis Program), capable of running in IBM-PC compatibles, was developed to reduce the time and cost of exhaust system optimization. ESTAP solves one-dimensional transient heat transfer problems of exhaust systems. It can predict the surface temperature of exhaust pipes and the exhaust gas temperature at the inlet of an underbody catalytic converter during the first 200 seconds of FTP-75 test. Results showed that the exhaust gas temperature can be accurately predicted, and ESTAP is an effective tool to optimize exhaust systems.
