Abstract

Fuel at a regulated pressure passes from a fuel to tank one or more fuel injectors disposed in fuel injector housings formed in mounting blocks that are mounted to the sides of a carburetor center section. Each injector is in fluid communication with a booster venturi ring that is suspended in each carburetor barrel. The injectors intermittently deliver high pressure pulses of fuel to the booster venturi rings which disperse the fuel into the airstream. The high velocity of the airstream passing through the suspended booster venturi ring decreases the pressure of the airstream, resulting in greater atomization of the injected fuel.
