正化装置。In an engine fuel supply system that improves combustion by providing a side flow passage between the vicinity of the throttle bore and the vicinity of the combustion chamber or intake valve in addition to the main intake passage, a side flow is injected into the combustion chamber to improve combustion. A side flow air intake hole is provided on the throttle bore wall at a position substantially opposite to the bypass hole across the valve shaft, and an air passage that introduces venturi upstream air or external air that has passed through a separate filter in the middle of the side flow passage. An apparatus for optimizing an air-fuel ratio at high temperatures, characterized in that a heat sensitive body valve is disposed in the air passage.
