PURPOSE:To improve the starting of an internal-combustion engine at low temperature without making the operating person control the engine, by providing a device for feeding plural fuels to the engine and by feeding the auxiliary fuel to the engine at its low-temperature starting regardless of the selected position of a fuel changeover means. CONSTITUTION:When the operating person of an engine has turned on a starter switch 40 at the low-temperature starting of the engine, a gasoline shutoff valve 24 is opened regardless of the changeover state of a fuel changeover switch 38, as long as a temperature switch 44 remains closed, so that gasloine is supplied from a gasoline carburetor 12 into an intake passage 11. In the normal operation of the engine, the operating person turns the fuel changeover switch 38 to a side (b) to open a liquefied petroleum gas shutoff valve 30 and close the gasoline shutoff valve 24 to feed only liquefied petroleum gas into the intake passage 11 from a liquefied petroleum gas adapter 14. |
