Claims

[Scope of utility model registration request]

- In an internal combustion engine equipped with an alcohol vaporizer, one end communicates with an alcohol accelerator pump or a float chamber of the alcohol vaporizer, and the other end connects an accelerating fuel co-feeding pipe that opens near the intake port of each cylinder, and the accelerating fuel a solenoid valve inserted into the supply pipe; a solenoid valve control means for opening and closing the solenoid valve in conjunction with the throttle valve opening; and a solenoid valve control means inserted upstream of the acceleration fuel supply pipe for accelerating the alcohol when the engine is relatively hot A three-way solenoid valve is introduced into the fuel supply pipe and is automatically switched to introduce auxiliary gasoline into the accelerating fuel supply pipe when the engine is relatively low temperature; For auxiliary gasoline that supplies gasoline to the above three-way solenoid valve. An acceleration increase device for an alcohol fuel vaporizer, characterized by comprising an acceleration pump.
