US Patent:

49521829, Aug 28, 1990

Filed:

Jul 7, 1989

Appl. No.:

7/377024

Inventors:

Mark D. Curtis - Oshkosh WI
James L. Wagner - Neenah WI

Assignee:

Brunswick Corp. - Skokie IL

International Classification:

B63H 2126

US Classification:

440 89

Abstract:

An exhaust relief system for an outboard motor includes an exhaust chamber into which exhaust is discharged from the engine. A first passage in communication with the exhaust chamber provides contraction of the exhaust as the exhaust passes rearwardly, from which the exhaust is discharged into an expansion chamber which substantially surrounds the exhaust chamber. From the expansion chamber, the exhaust is routed through and contracted into a second passage in communication with the expansion chamber, after which it is discharged to atmosphere. The tortuous path provided by the exhaust relief system of the invention, along with the repeated expansion and contraction of the exhaust as it flows to atmosphere, provides a muffling effect at idle operation.

Assignee:

Brunswick Corporation - Skokie IL

International Classification:

F02B 7502

US Classification:

123 73A

Abstract:

A two stage carburetor for introduction of an air-fuel mixture into the crankcase of a two-stroke marine engine includes a carburetor body that defines a pair of throttle bores, one of which has a reduced cross-sectional area. The throttle bores deliver an air-fuel mixture to separate and distinct reed blocks having comparable cross-sectional areas.

Assignee:

Brunswick Corporation - Lake Forest IL

International Classification:

F01M 104

US Classification:

123196R

Abstract:

A lubricating system for an internal combustion engine is provided wherein oil flows from a compressor oil drain port to a region of the engine which is to be lubricated. The source of lubricating fluid, such as the compressor, is transmitted through a first conduit between the compressor and a lubricant supply region of the engine block. The lubricant supply region is located between a first seal region, or labyrinth seal, and a region to be lubricated which can be a center main bearing. The region to be lubricated is located between the lubricant supply region and a first lower pressure region of the engine, such as the crankcase region associated with one of the cylinders of the engine. A check valve is used to resist flow of the lubricating fluid in a direction from the lubricant supply region to the lubricating fluid source.

Appl. No.:

6/038599

Inventors:

James M. Hundertmark - Fond du Lac WI
James L. Wagner - Butte des Morts WI

Assignee:

Brunswick Corporation - Skokie IL

International Classification:

F02M 116

US Classification:

1231875R

Abstract:

A cold start fuel enrichment system for an internal combustion engine uses fuel from the upper carburetor for enriching the air-fuel mixture in the lower carburetors by gravity feed. A fuel line runs from the upper carburetor float bowl to the throttle bores of the lower carburetor. A solenoid valve in the fuel line controls its operation.

Assignee:

Brunswick Corporation - Skokie IL

International Classification:

F02B 3304

US Classification:

123 52M

Abstract:

In a two cycle internal combustion engine (2), a fuel injection system is provided with a low profile compact intake manifold (22) mounted to the crankcase (8) by an adaptor plate (24) and defining an intake air flow path in a first direction (28) behind the manifold (22) through a gap between the manifold (22) and the crankcase (8) provided by the adaptor plate (24). Intake air then flows (32) into throttle bore passages (30) from behind the manifold and then reverses direction and flows through supply passages (34) having fuel injectors (38) and then into the crankcase (8). The passages share a common plenum (42) within the manifold. The fuel injectors (38), their electrical connectors (48) and a common rigid fuel supply rail (44) are all in the common plenum (42) entirely within the low profile manifold (22) and sealed from moisture and salt in a marine environment.

Appl. No.:

7/219086

Inventors:

James L. Wagner - Neenah WI

Assignee:

Notron Engineering AG - Zollbruck

International Classification:

E05C 1910

US Classification:

292128

Abstract:

An interlock mechanism is provided for a latch assembly which releasably secures upper and lower cowl sections of an outboard motor. The interlock mechanism is movable between a locking position and a release position, and is normally disposed in its locking position, such as by a coil spring. The interlock mechanism is mounted to the latch handle, which is pivotably mounted to one of the cowl sections. A hook is interconnected with the latch handle, and is engageable with a catch assembly provided on the other of the cowl sections. The interlock assembly normally engages a stationary engagement pin provided on one of the cowl sections, which prevents accidental pivoting movement of the latch handle. The interlock mechanism is manually movable to its release position, so that the latch handle can be pivoted so as to disengage the hook from the catch mechanism.
