Abstract
A manifold for a fuel injected engine has several fuel injectors that are connected to a common air assist passageway for each bank of cylinders. This passageway is preferably supplied with assist air from a central location, between two of the fuel injector pockets that intersect the air assist passageway in each bank of cylinders. This air assist passageway may be formed integral with a manifold, or may be separately formed together with the injector pockets as an air assist rail. The air assist passageway preferably intersects the center line of the fuel injector pockets and is formed by inserting pins that define the interior surface of the passageway into a mold cavity to intersect and pass through bosses that define the fuel injector pockets.
