ABSTRACT:
A multicylinder internal combustion engine has an intake manifold with one or more auxiliary fluid distribution networks for directing byproduct fluids to each cylinder to insure balanced flow. The byproduct fluids include crankcase vapors and fuel vapors from an adsorption canister, and recirculated exhaust gas. The crankcase and purge vapors are mixed in a common network of flow passages formed by grooves formed into the face of an intake manifold mounting flange, with the exhaust gas in a separate sealed network of grooves. Assist air flow to the injector ports is directed through yet another network of grooves in the flange face.
