PURPOSE:To improve the heat-resisting restart performance by making each map value of the start injection time and the increase coefficient after start of the water temperature larger than the normal value, on the restart for a prescribed time after an engine key is turned OFF. CONSTITUTION:Liquid fuel is supplied into a fuel injection valve 5 installed onto the throttle chamber 3 of an intake pipe 2 from a fuel cylinder 6 through a feed pipe 7 equipped with a fuel pump 9, and the rest fuel is returned into the gas phase side of the cylinder 6 through a return pipe 10 equipped with a regulator 11. Each signal supplied from a fuel temperature sensor 15, pressure sensor 16, timer 21, etc. is input into a controller 17, and on the restart for a prescribed time by a timer which is started by the switching OFF of an engine key, each map value of the starting injection time and the increase coefficient after start for the fuel temperature is made larger the normal value, and a sufficient quantity of fuel is supplied.
