ABSTRACT:
A rotor-type carburetor is provided with a specially designed spray ring which centrifugally discharges atomized fuel droplets in two different sizes for mixture with engine-ingested air traversing the interior of the carburetor and driving its rotor section. Larger droplets are forced outwardly through an annular series of discharge openings formed in the ring, while smaller droplets are formed by the passage of fuel over an annular spray edge extending around the bottom of a radially inwardly bent lower end portion of the ring. This simultaneous formation and discharge of two series of differently sized atomized fuel droplets improves the overall performance of the engine and reduces the level of its emission pollutants. The spray ring also functions to automatically vary, in a predetermined manner, the flow rate relationship between the differently sized fuel droplets as a function of engine speed to further enhance engine performance. The carburetor is also provided with a capillary action fuel scavenging system which functions to capture fuel centrifugally discharged from the spray ring during rotor spin-down periods to prevent the undesirable delivery of fuel to the engine during such periods. Fuel captured by the scavenging system is returned to the engine fuel supply system.
