However, S.I. engine emits carbon dioxide, which becomes the origin of global warming. Therefore, it is necessary to improve the thermal efficiency of S.I. engine for reducing the emission of the carbon dioxide. A gas flow is often generated in the cylinder of the engine in order to promote combustion for improving the thermal efficiency. While the gas flow increases the thermal loss, as the heat transfer on combustion chamber is promoted. So it is necessary to be obtained relation between the flow velocity and the heat transfer coefficient. Nevertheless, it is difficult to measure the velocity of the in-cylinder burnt gas flow. Whereas, it is thought that the heat transfer coefficient is related to the time after ignition. This paper reports that the heat transfer coefficient on the combustion chamber walls is obtained as a function of time by using of the relation between Nusselt number and Fourier number.}, pages = {165--170}, title = {火花点火機関における燃焼室壁面での熱伝達(ヌセルト数とフーリエ数の関係)}, volume = {43}, year = {2014}, yomi = {タカハマ, トモヒロ and ナガセ, ヨシノリ and トモマツ, シゲキ and キムラ, マサトシ and タカハマ, トモヒロ} }
