Abstract:
A fuel gas has a gas including at least 40 weight % or more of 1-butene and propane, or at least 56 weight % or more of 1-butene and propylene. A combustion type power tool is driven by the fuel gas. A compressed gas container for a combustion type power tool has an inner side vessel filled with the fuel gas. When the fuel gas includes propane, 1-butene may be equal to or higher than 59 weight % and equal to or lower than 95 weight %. When the fuel gas includes propylene, the 1-butene may be equal to or higher than 70 weight % and equal to or lower than 96 weight %.
