Claims

[Claims for Utility Model Registration] 1. In a single-barrel carburetor having a plurality of throttle valves, the throttle valves are arranged so as to extend from the upstream side of the vent lily portion on the secondary side to the downstream side adjacent to the throttle valve on the secondary side. a first valve device provided in the bypass passage; a first step motor that controls the operation of the first valve device; and an air passage adjacent to the throttle valve on the primary side from the float chamber. A fuel increase passage leading to the downstream side, a duty solenoid valve device provided in the increase fuel passage, engine rotation speed, cooling water temperature, intake pipe pressure,
A computer control device that uses the throttle valve opening degree as input information to supply outputs for controlling the flow rate of air passing through the bypass passage and the flow rate of fuel flowing through the increase fuel passage to the step motor and the duty solenoid valve device, respectively. A vaporizer consisting of units. 2. In a single-body carburetor having a plurality of throttle valves, an air passage that bypasses the throttle valve so as to extend from the upstream side of the secondary side bench lily portion to the downstream side adjacent to the secondary side throttle valve; a first valve device provided in the bypass passage; a step motor that controls the operation of the first valve device; an increase fuel passage extending from the float side to a downstream side adjacent to the primary throttle valve; and the increase fuel passage. Multiple duty solenoid valve devices installed in the passage, engine speed, cooling water temperature, intake pipe pressure,
An output control signal for controlling the flow rate of air passing through the bypass passage is supplied to the step motor using the throttle valve opening degree as input information, and an output control signal for controlling the flow rate of the increase fuel flowing through the increase fuel passage is supplied to the plurality of output control signals. A carburetor consisting of a computer control unit that feeds each duty solenoid valve system separately.
