Abstract
An intake manifold (10) includes a fuel rail cavity (30) which receives a metallic fuel rail (14) enclosed by a molded fuel rail cavity cover (32). The fuel rail (14) communicates with each of a plurality of engine cylinders (16) through a fuel module (18). An injector cup (28) fits upon each module cylinder to provide an interface between the fuel module and the fuel rail. Another intake manifold (10) includes a fuel rail (14) which directly interfaces with each fuel module (18) through a bellows (38) attached directly thereto.
