An Investigation of Instantaneous Heat Transfer Rates in the Exhaust Port of an Internal Combustion Engine

摘要: Abstract : Recently, the growing concern over exhaust emissions, cooling requirements and design of system devices has led to study instantaneous heat transfer rates in straight portion engine port itself. In this study, experimental measurements were made gas temperatures wall surface at four different positions for a range operating conditions. The calculated coefficients found be significantly dependent on geometrical position port, speed load depicted consistent trend results.
