Abstract

PURPOSE: To obtain a fuel ratio control device in which the influence of the back fire of an internal combustion engine is reduced by installing an air temperature detecting hot-wire at the rear part of a buffer chamber provided at the communication path which communicates a throttle chamber with an air cleaner.
CONSTITUTION: The air flow detecting hot-wire 10 is provided in a bias passageway 9 provided in a Venturi part 11 at the upper part of a throttle chamber 3, and further a buffer chamber 12 of a large capacity is formed in an air suction path 4 communicating the throttle chamber 3 with an air cleaner 14. At the rear part of the buffer chamber 12 there is provided an air temperature detecting hot-wire 13. By the provision of the detecting hot-wire at the above described position, even when the back fire of the internal combustion engine is generated, a control unit 20 can control the operation of a fuel injection valve 25 without receiving the influence of the back fire of the internal combustion engine.
