The thire paper examined the effect of turbulence by combustion causes to heat loss. But in real gasoline engine, the air fuel mixture, which inhaled it in cylinder includes initial turbulence. Therefore effect of initial turbulence of mixture was examined to estimate heat loss of gasoline engine in this paper. The initial turbulence was expressed using a simple model in which the momentum of turbulence damps when turbulence moves from unburned gas to burned gas. The expression to estimate heat loss is expressed as next by using the model. [numerical formula] Where the third term expressed the effect of initial turbulence and the coefficient: Cd≈0.24 has expressed damping of initial turbulence.
