It is important to quantify the diffusion behavior of evaporative fuel gas in order to control the evaporate emission from carbon canister. Especially, it is necessary to take the changes in adsorption-desorption amount and diffusion coefficients by air temperature into account to design carbon canister satisfied for various conditions of air. In this study, we estimated diffusion coefficients in carbon canister for the binary system of butane and nitrogen and examined temperature-dependence of diffusion coefficients.
