A mathematical model of exhaust port heat loss was evolved using an electrical analog of heat transfer. Good correlation with experimental results is demonstrated for comparatively simple design variables. The critical effects of limiting metal-to-metal contact between port liner and port wall is predicted. The limitations of the present model for studies involving complex design variables is discussed.
