Analytical and Experimental Evaluation of a Thermally Insulated Automotive Exhaust System 940312
For an automotive exhaust system, analytical evaluation of coatings, dual wall, multiwall, and blanket insulation methods indicated that the blanket insulation provided the best method for heat containment. An experimental vehicle was tested with and without a blanket insulation on the exhaust system over a demanding heat protection cycle. The exhaust gas, pipe wall, surrounding air, and adjacent component temperatures at 25 locations along the pipe are reported indicating reduced outer wall temperatures and good containment of the heat. A comparison of the heat lost through the exhaust system walls is presented.
