Abstract:

An integrated fuel and air induction system for use on an internal combustion engine two-piece intake manifold with a fuel metering body defining an integral portion thereof. The manifold contains the fuel metering body which defines a fuel plenum therein. The plenum has an inlet for pressurized fuel, a pressure regulator, and a fuel outlet. Disposed within the fuel plenum, in fluid communication with one another, the inlet and the outlet, are a plurality of fuel injectors. The fuel injectors have outlets which extend through the fuel meter body and delivery fuel to the intake ports of the associated engine through flexible fuel lines terminated by pressure pulse activated poppet nozzles providing a significant degree of application flexibility. The fuel meter body mounts within the intake manifold such that fuel and electrical connections extend out of the manifold for simplified source attachment.
