METHOD FOR IMPROVING HOMOGENEITY OF FUEL MIXTURE OF CARBURETOR ENGINE OPERATING UNDER LOAD Russian patent published in 2000 - IPC

FIELD: mechanical engineering; carburetor engines. SUBSTANCE: when engine crankshaft speed exceeds value defined by type of engine and carburetor, control unit generates at its outlet a low level signal with delay which is supplied to electropneumatic valve through which atmospheric pressure acts onto diaphragm with shutoff member. By shifting the latter relative to carburetor in direction of idling system outlet hole, hole is closed by shutoff member. Through progression system holes air is fed along air supply channel into above throttle space of carburetor primary mixing chamber. EFFECT: enhanced homogeneity of fuel mixture, reduced consumption of fuel. 2 dwg
