摘要: A cylinder head for an engine defines first and second exhaust runners fluidly coupled to an exhaust passage extending transversely in the head to an exhaust port on an exhaust side. The head defines an exhaust gas recirculation (EGR) passage connected to the exhaust passage and extending longitudinally to an EGR port on the exhaust side. The head also defines a cooling jacket passage adjacent to and substantially surrounding the EGR passage to cool EGR gases prior to cooling by an EGR cooler.

摘要: Exemplary arrangements for drive chains are disclosed. In one exemplary arrangement, a tooth shaped link member for a drive chain comprises a web portion, a first side tooth, a second side tooth and a central guide tooth. The web portion extends between opposing side portions of the link member. The first side tooth and the second side tooth each include an apex that is oriented at an angle to extend toward the central guide tooth. In another exemplary arrangement, a drive chain comprises a plurality of inner links that are operatively connected to a plurality of outer links, where a pair of rollers are mounted between the inner links with a pin being positioned between the rollers.

摘要: An engine is provided with a cylinder head defining a coolant jacket therein that is formed from a series of passages interconnected by a series of curved junctions to direct coolant about spark plugs, exhaust valves, and an integrated exhaust manifold in the head. The cooling jacket has a first longitudinal passage with an annular section about a spark plug, a second longitudinal passage with an annular section about an exhaust valve, and a third passage surrounding an integrated exhaust manifold and fluidly connecting the first and second passages. The first passage has a continuously decreasing area and the second passage has a continuously increasing area in a direction of coolant flow.

摘要: An engine includes a cylinder block with first and second saw cuts intersecting a block face on opposed sides of a block bore bridge. A cylinder head has third and fourth saw cuts intersecting a head face on opposed sides of a head bore bridge. A gasket is placed between the block and the head. The gasket defines a cooling passage adapted to fluidly connect the first, second, third and fourth saw cuts and cool the interbore region of the engine. The cooling passage has an inlet and a pair of outlets.

摘要: An engine has a cylinder head defining an intake port with a roof defining first and second valve guide bores upstream of first and second siamesed intake valve seats for a cylinder. The head has first and second asymmetric fairings extending outwardly from the roof and positioned directly upstream of respective bores. Each fairing has an inner wall intersecting an outer wall along an upstream edge and an inclined planar roof wall extending between the inner and outer walls. A method of forming the cylinder head and engine is also provided by milling the fairings from a roof preform formed with the intake port of the head.

摘要: An engine is provided with a cylinder head having a bridge region surrounded by an exhaust face, an exhaust passage intersecting the exhaust face, and an exhaust gas recirculation (EGR) passage fluidly coupled to the exhaust passage and intersecting the exhaust face. The head defines an upper cooling jacket having a cavity or fluid passage extending from the jacket towards a head deck face and to a closed end wall within the bridge region. The cylinder head is cooled by directing coolant from a lower jacket to an upper jacket via a drill passage adjacent to an exhaust face of the head, diverting the coolant exiting the drill passage into the fluid passage or cavity along a rib. Coolant is then directed from the fluid passage into an EGR cooling passage formed by the upper jacket adjacent to the exhaust face and about the EGR passage.
