Abstract
In one embodiment, a cylinder head (10) and a runnerless intake manifold (12) are assembled together and cooperatively define an air manifold (14) and a fuel manifold (16) for supplying air and fuel respectively to engine cylinders in an engine block to which cylinder head (10) is fastened. In another embodiment, the air manifold is the same, but the fuel manifold (66) is defined by a bore (68) and holes (70) in the intake manifold (60).
