Japanese Patent JPS5032907
Kind Code:
B2
Abstract:
A device for optimizing the air/fuel ratio of a combustible mixture produced in a carburetter when atmospheric pressure and temperature deviate from given levels. When a bellows extends in response to the deviation from the given levels, atomospheric air is supplied downstream of a carburetter throttle valve through a diaphragm valve assembly responsive to the extension of the bellows during idling or light-load operation of an engine, while air is supplied to a main mixture supply passage through another diaphragm valve assembly responsive to the operation of the first-mentioned assembly during full-load operation.
