There exist a great many theoretical researches on the periodic heat transmission in the internal combustion engines. Many of them discuss the problem only from the point of view of heat conduction in the solid wall, but there are few reports on the theory of heat conduction in the working gases. H. Pfriem and K. Elser have derived the energy equation of the gases especially in the boundary layer near the cylinder wall and solved it. But they have calculated only the heat transferred from the gas space to the wall under the condition that there were not any heat sources in the gases and the adibatic compression and expansion were repeated. It is the object of the present paper to introduce the term of heat quantity in the energy equation by applying the conception of the polytropic change. By this means we can calculate the heat flow from the gases to the combustion chamber wall, when the gas cycle is quite similar to the spark-ignition engine. In the latter part of the present report, the numerical calculation is achieved, and the calculated results are compared with my experimental results.
