Claims

[Scope of utility model registration request]

The increasing air passage 10 bypasses the throttle valve 3 of the carburetor 1 and introduces the atmosphere downstream of the throttle valve 3 when the engine is at a high temperature, and the increasing air passage 10 introduces atmospheric air into the downstream side of the throttle valve 3 when the engine temperature changes.
In the air increasing device for engine high temperature, which includes a valve 12 that conducts and shuts off a valve 12, a part of the atmosphere guided to the downstream side of the throttle valve 3 is passed through the space above the oil level in the float chamber 6 of the carburetor 1. An air increase device for when the engine is at high temperature, which is equipped with a function to reduce the pressure in the float chamber.
