Abstract: A cylinder head defines an inlet port having an exit. A valve seat insert defines a seat cut surface that is disposed adjacent to the exit of the inlet port. A cross section of the inlet port parallel to a centerline of the inlet port defines a long turn edge of the inlet port cross section. The long turn edge of the inlet port cross section defines a flow path trajectory of the inlet port. The seat cut surface and the flow path trajectory are substantially aligned to extend the flow path trajectory of the long turn edge of the inlet port cross section across the seat cut surface.

Abstract: A partially integrated manifold assembly is disclosed which improves performance, reduces cost and provides efficient packaging of engine components. The partially integrated manifold assembly includes a first leg extending from a first port and terminating at a mounting flange for an exhaust gas control valve. Multiple additional legs (depending on the total number of cylinders) are integrally formed with the cylinder head assembly and extend from the ports of the associated cylinder and terminate at an exit port flange. These additional legs are longer than the first leg such that the exit port flange is spaced apart from the mounting flange. This configuration provides increased packaging space adjacent the first leg for any valving that may be required to control the direction and destination of exhaust flow in recirculation to an EGR valve or downstream to a catalytic converter.

Abstract: A secondary air injection or SAIR system is illustrated and described which includes a first air injection path defined by in part by a lower ditch formed in the head mounting surface of the cylinder block, and a second air injection path defined in part by a second ditch formed in the block mounting surface. The cylinder head gasket is used to separate and seal the first ditch from the second ditch. The first and second air injection paths are separate and isolated from one another such that secondary air may be selectively introduced through the first air injection path into the first exhaust leg and selective introduced through the second injection path into the second exhaust leg independent of the first air injection path.
