Title: Fuel-air ratio (Lambda) correcting apparatus for a rotor-type carburetor for integral combustion engines

Abstract

This patent describes a fuel-air ratio correcting apparatus in a rotor-type carburetor for internal combustion engines with spark ignition for producing ingestion air with fuel-air ratios within a predetermined range defined by lean and rich limits matched to the requirements of the various operational points of the internal combustion engine. The rotor-type carburetor has a rotating element including a turbine which is driven by a turbine driving airstream which is induced by the engine and which becomes at least a portion of the ingested air stream, the rotating element containing a centrifugal pump for delivering a quantity of fuel which is in a substantially constant ratio to the rotational velocity of the rotating element. The fuel is delivered to a coaxial atomization means on the rotating element for broad-casting atomized fuel into the driving airstream. The centrifugal pump is sized to deliver a quantity of fuel to the driving airstream to establish a fuel-air ratio at one limit of the predetermined range, and means for sensing one or more parameters(s) affecting operation of the internal combustion engine and for selectively varying the volume of at least one of the constituents of the fuel-air mixture ingested by the engine for establishingmore » a predetermined fuel-air ratio variable over the remainder of the range of fuel-air ratios in dependence on one or more measured operating parameter(s) of the internal combustion engine. The rotor-type carburetor has a rotor driven via an impeller by the ingested air stream, the rotor containing a centrifugal pump for delivering via at least one lateral fuel discharge bore a qantity of fuel which is in a constant ratio to the ingested air and which is dimensioned for a lean mixture.« less
