Abstract

PURPOSE:To stabilize idle running by increasing an amount of fuel for idling when alcohol concentration is over a set value in a device for supplying mixture fuel of alcohol and gasoline. CONSTITUTION:An auxiliary slow fuel path 4 is branched from a slow system fuel path 2f of a carbureter 2 and communicated to an auxiliary port 5 which opens to an intake path 1 downstream an idle port 2c. This auxiliary fuel path 4 is provided with a path opening/closing valve 6 consisting of an electromagnetic valve which makes fuel control by means of a control 8 receiving the output of an alcohol concentration sensor 9 provided projectingly in a float chamber 2a via an idle switch 7 which closes in idling. Thus, the rate of alcohol in mixed fuel F in the float chamber 2a is increased, and when the alcohol concentration is higher than a set value and during idle operation, the valve 6 is opened so that fuel can be also supplied from the auxiliary port 5.
