摘要：PURPOSE:To contrive an improvement of operation characteristics, by controlling a fuel quantity according to the cooling water temperature of an engine, in a device maintaining an air quantity in a bypass duct at a given level. CONSTITUTION:An air flow sensor 32 is provided in a bypass duct 30. An air metering orifice 36 forming an air metering part by serving together with a tapered air metering valve 38 is provided downstream the bypass duct. The air metering valve 38 is made to actuate by control circuit 72 so that an air quantity passing through the air metering part arrives at a given level. The cooling water temperature of an engine is detected by a sensor 74 and a fuel quantity is corrected by the cooling water temperature. With this construction, operation characteristics are improved.
