Abstract: | The warm-up cycle for an automobile engine with an insulated exhaust pipe between the engine and the catalytic converter is considered. The mathematical model for the heat transfer in the insulated exhaust pipe is presented. An efficient numerical algorithm for this model is also constructed and the numerical results are obtained and compared with measurements. Some possibilities for the geometrical optimization of the exhaust pipe are discussed. |
