Claims
- 1. An apparatus, comprising:
an internal combustion engine cylinder head having an internal water jacket and a longitudinal axis, said cylinder head including an intake passage system formed in the cylinder head adapted for the delivery of a fuel to a plurality of combustion chambers and an exhaust passage system formed in the cylinder head adapted for the passage of an exhaust gas from the plurality of the combustion chambers; a first exhaust gas recirculation passage formed within said cylinder head and extending along said longitudinal axis, said first exhaust gas recirculation passage having a first inlet and a first outlet; a second exhaust gas recirculation passage formed within said cylinder head and spaced from said first exhaust gas recirculation passage and extending along said longitudinal axis, said second exhaust gas recirculation passage having a second inlet and a second outlet; and a plug member positioned within an opening defined in said cylinder head between said exhaust gas recirculation passages and in fluid communication with said exhaust gas recirculation passages, said plug member preventing the flow of exhaust gas between said exhaust gas recirculation passages at said opening.
- 2. An internal combustion engine cylinder head, comprising:
an elongated body having a first end portion and an opposite second end portion, said body including a first exhaust gas recirculation passage formed therein between a first inlet and a first outlet and a second exhaust gas recirculation passage formed therein between a second inlet and a second outlet, said inlets are formed proximate said first end portion and said outlets are formed proximate said second end portion, wherein exhaust gas flow within said first exhaust gas recirculation passage between said first inlet and said first outlet is separated from exhaust gas flow within said second exhaust gas recirculation passage between said second inlet and said second outlet by a barrier formed by a portion of said body and a plurality of plugs.
- 3. An internal combustion engine cylinder head, comprising:
an elongated metallic body having a front end and an opposite rear end and a longitudinal axis, said body has an exhaust gas recirculation passageway system formed therein with an exhaust gas recirculation inlet at said rear end and an exhaust gas recirculation exit at said front end, said exhaust gas recirculation passageway system includes at least one flow path extending from said exhaust gas recirculation inlet to said exhaust gas recirculation exit that is free of obstructions that limit the drainage of a liquid accumulated within said flow path.
