ABSTRACT:
A carburetor having a fuel mixing valve with multiple vanes which control the flows of main and secondary fuels into a valve mixing chamber. The octane rating of the fuel charge may be momentarily increased during periods of engine acceleration to permit the engine to have a higher compression ratio for optimum efficiency with a relatively low octane fuel. The fuel flow controlling vanes may be mounted on a common shaft for simultaneous movement or on separate support means for differential movement in response to an engine control. A fuel mixing valve is also disclosed for use with the second stage components of a two stage carburetor.
