Abstract
A combined air intake manifold and fuel delivery rail for an internal combustion engine which decreases manufacturing and assembly costs, as well as the weight of the engine. An air channel formed in a hollow portion of the manifold registers with air intake ports in the engine head which lead to the individual cylinders of the engine. An elongated recess in the underside of a mounting flange forms a fuel supply channel which communicates with fuel inlet openings in the engine head leading to fuel injectors for the engine cylinders. Seals may be provided between the manifold and the engine head to seal the air channel and the fuel supply channel.
