Abstract
A fuel delivery system for an internal combustion engine includes induction conduits of effectively equal flow resistance for guiding separate air and fuel streams to each of the cylinders of the engine. Each induction conduit includes at its entrance a sleeve venturi for inducing fuel into the air stream and a booster venturi. A fuel injector applies fuel at high pressure to the booster venturi. Flow modifiers may be positioned in the venturi throat and down stream of the venturi for modifying the flow of the stream of air after the fluid has been induced and injected into the stream of air for further subdividing the fuel vapor for increased effect of combustion of the fuel and air mixture.
