Appl. No.:

09/933673

Inventors:

Franz Laimböck - Thal, AT
Christopher N. Cowland - Ann Arbor MI
Robert J. Moran - Ann Arbor MI

Assignee:

AVL List GmbH - Graz

International Classification:

F02F 700

US Classification:

123195P, 123195 HC, 123 532

Abstract:

A four cycle outboard internal combustion engine for driving a watercraft with a cylinder housing having cylinders arranged in at least two rows, wherein a piston is reciprocating in each cylinder, the pistons driving an approximately horizontally accommodated propeller drive shaft by way of an approximately vertically arranged crankshaft, each cylinder bank being provided with cylinder head sealing surfaces for a cylinder head housing receiving gas shuttle valves and wherein the cylinder head sealing surfaces of all of the cylinders are arranged in one single cylinder head sealing plane and an exhaust main manifold for all of the cylinders is arranged approximately parallel to the crank shaft in the cylinder head housing in the area of a central plane of the motor which is configured parallel to the crankshaft. One crankshaft is provided for each cylinder bank, the crankshafts having a stable relative speed ratio and acting upon the propeller drive shaft through a common jackshaft.

Appl. No.:

12/248076

Inventors:

Robert J. Moran - Ann Arbor MI, US

Assignee:

GM Global Technology Operations, Inc. - Detroit MI

International Classification:

F02B 47/08
F02B 47/10

US Classification:

12356812

Abstract:

An exhaust gas recirculation system for an engine provides three modes of operation. In a bypass mode, exhaust gas bypasses a heat exchanger. In a single pass mode of operation, exhaust gas flows through the heat exchanger passageways. In a dual pass mode of operation, exhaust gas flows through the heat exchanger passageways in a manner that provides a longer effective flow length through the heat exchanger compared to the single pass mode, thereby to increase cooling efficacy.

International Classification:

B25G 3/00

US Classification:

403 16, 403 12, 411103, 411999

Abstract:

An assembly for connecting a component having a base to a surface includes a fastener and a retainer having a clamp portion for capturing a shank of the fastener, and for aligning the fastener and an optional gasket with the base. The retainer automatically separates from the fastener when the fastener is tightened, and may include a recovery feature to allow recovery of the retainer after separation. A method for facilitating connection of a component and gasket to a surface includes inserting a threaded fastener into a base of the component, capturing the fastener within a clamp portion of a retainer, and positioning a surface of the retainer adjacent to the base. A tab portion of a gasket or the base can be inserted into a slot in the retainer to thereby secure the retainer to the base prior to connecting the component to the surface.

International Classification:

F01M 9/10

US Classification:

123 9034, 123 9033, 2988806

Abstract:

A method of forming a cylinder head may include machining an upper surface of a cam tower of the cylinder head to form a generally planar surface. An oil passage may be drilled in the upper surface to provide an oil feed. A bearing bore may be formed in the upper surface of the cam tower. The bearing bore may include a recess having first and second circumferential ends. The oil passage may intersect the first circumferential end.

US Classification:

417406, 606052

Abstract:

Exemplary embodiments of the present invention are directed towards an apparatus and method for fluidly coupling a turbocharger to an internal combustion engine. In one embodiment, a turbocharger mount for fluidly coupling a turbocharger to an exhaust system of an engine is provided. The turbocharger mount includes a housing portion and a mounting flange extending from the housing portion. The housing portion defines a cavity therein and a first inlet opening in fluid communication with the cavity, a first outlet opening in fluid communication with the cavity, and a second outlet opening in fluid communication with the cavity.

International Classification:

F02M 25/07
F01L 1/34

US Classification:

12356811, 123 9015

Abstract:

An engine assembly may include a first exhaust valve lift assembly, a first exhaust valve, and a first camshaft. The first exhaust valve lift assembly may be operable in first and second operating modes. The first exhaust valve may be engaged with the first exhaust valve lift assembly and may be in communication with an engine combustion chamber. The first camshaft may include a first exhaust lobe engaged with the first exhaust valve lift assembly and defining a profile including a first exhaust region and a first exhaust gas recirculation (EGR) region. The first exhaust valve may remain closed when the first EGR region engages the first exhaust valve lift assembly during the first operating mode and may be opened when the first EGR region engages the first exhaust valve lift assembly during the second operating mode to provide exhaust gas flow into the combustion chamber during an intake stroke.
