The heating value transported by conduction has a lot of cases ignored when heat transfer in combustion chamber of gasoline engine was analyzed. The reason is because the value is smaller than the value of convection generally. But gas flow hardly exists in the vicinity of chamber wall where heat transfer is actually done. In this case it needs to be made clear whether the effect of conduction can be ignored. Therefore analysis and experiments were done with constant volume chamber in this paper. As a result that heat flux which was represented by conduction was let by the next expression. [numerical formula] It became clear that heat loss quantity estimated by, tinis expression was about 30% of true heat loss. And it is supposed that gas flow formed by combustion has influenced remainder 70%.
