According to the result of the first paper, the quantity of heat loss by conduction was approximately 30% of the true heat loss without the initial turbulence in the supplied air-fuel mixture. In addition, it was supposed that the other 70% of the heat loss were produced by the gas turbulence, which was caused by the combustion. Therefore, that turbulence of gas, which was expressed using mixing length model of Prandtl and conservation law of angular momentum of turbulence etc., was examined by this paper. Consequently, the energy equation gets possible to be solved using the turbulence model and approximation clarification. The equation to estimate the quantity of heat loss to the combustion chamber wall was able to be expressed using simple variables such as pressure and temperature, and the equation is shown in next.
