Abstract
An experimental system has been constructed to study the heat transfer processes in the straight section of the exhaust port of a four-stroke, spark ignition engine. The effects of engine variables on the steady-state heat transfer rates have been studied at four locations in the exhaust port. It was found that the heat transfer rates have a significant dependence upon the location within the exhaust port. Data have been correlated in the form of a Nusselt-Reynolds number relationship for local and spatially averaged steady-state heat transfer. It has been shown that the use of conventional steady-state heat transfer relationships for developing steady-state turbulent flow in pipes predicts heat transfer rates which are lower than those experimentally observed.
