Abstract
A method of programming exhaust gas constituents is disclosed which cooperates with a unique exhaust passage liner construction resulting in an improved self-cleaning technique for internal combustion engines. The liner comprises an apparatus which preferably subdivides the outer peripheral region of the exhaust so that the Reynolds number of the outer flow is below 2300 and therefore indicative of laminar or controlled turbulent flow. The laminar transient film between the passage wall and flow is enhanced by the transient film between subdividing walls and the flow, the composite acting to reduce the heat transfer coefficient between the total flow and wall of the exhaust passage.
