Recently, many authors have reported an equation for the heat transfer coefficient between the mixture and the cylinder wall of an engine. The dependency of these equations on the temperature, pressure and velocity of the mixture is different among the reports. Especially, the difference of the dependency on the temperature is great. Therefore, the authors reach the conclusion that the effect of the mixture-temperature is negligible. According to the above mentioned fact, the authors present an equation for the heat transfer coefficient on the basis of assumptions as follows : (1) the velocity is the sum of the mean piston velocity and the exhaust-suction gas velocity ; (2) the effect of the cylinder wall temperature is dominant. This equation is as follows : [numerical formula]
