Abstract

PURPOSE:To enable to keep a proper air fuel ratio in an internal combustion engine in which a mixed fuel of alcohol and gasoline is used by increasing or reducing the amount of the air to be introduced to the fuel which is sucked out to suction channel according to the concentration of alcohol. CONSTITUTION:When a fuel with an alcohol concentration lower than that of the prescribed concn. is used in engine operation, a solenoid valve 22, which is normally open, opens a gas mix channel 21, and proper amount of air is introduced through the gas mixing channel 21 via orifice 18, 19 in addition to main air bleed 7a, 7b in correspondence to fuel channel 5a, 5b, and is mixed into fuel sucked out in suction channel 8a, 8b. On the other hand, in case the alcohol concentration is higher than the prescribed concn., a switch 25 is switched on, interlocking with the alcohol concentration 26, and the solenoid valve 22 closes the gas mixing channel 21. Therefore, only the air from the air bleed 7a, 7b is mixed into the fuel, and thus vaporization to obtain a fuel-air mixture with a high fuel concn. is attained.
