Abstract
PURPOSE:To prevent an engine from stall due to over-rich air fuel ratio in a cool time by reducing correctively a desired fuel amount corresponding to the reduction of fuel temperature for a LPG engine. CONSTITUTION:A fuel path extending from a LPG regulator 7 to a Venturi tube 4 of an intake path is provided with a fuel temperature sensor 25, and a detecting signal of said sensor 25 is input to a controller 23 which calculates a desired fuel amount corresponding to the running condition while correctively reducing the desired fuel amount as the temperature of said controller is lowered according to the fuel temperature. Thus, the opening of fuel path 5 is controlled by a step motor 9 to prevent air fuel ration from becoming over-rich in a cool time.
