Abstract
The concept of mean cycle temperature has been used, by Seale and Taylor (1)§, to calculate heat transfer in pistons and liners of internal combustion engines. However, this technique cannot be used for exhaust valves because the valve temperature exceeds the gas mean cycle temperature. In this work it is shown that a ‘mean temperature’, based solely upon radiation considerations, yields a simple method for assessing the maximum temperature of exhaust valves and that the results obtained from engine tests are in close agreement with those predicted. The engine used in the investigation was a Mirrlees Blackstone K Major four-stroke diesel engine of 380 mm bore, operating with a b.m.e.p. of 1660 kN/m2at 600 rev/min.Keywords
