Dec 21, 1999

Appl. No.:

09/468582

Inventors:

Mark Noble - Pleasant Prairie WI
Charles T. Rogan - Kenosha WI
Douglas A. Trudeau - Lake Orion MI

Assignee:

Bombardier Motor Corporation of America - Grant FL

International Classification:

H02K 127

US Classification:

310 74, 310 42, 310 43, 31015621, 31015626, 29598, 74572

Abstract:

A flywheel ( ) having a molded cage ( ) formed around a plurality of magnets ( ) attached to the flywheel ( ). The cage ( ) extends into one or more grooves ( ) formed in the flywheel ( ) to resist the shrinkage of the cage 30 inside diameter as it cools following an injection molding process. The gap ( ) between the cage ( ) and magnets ( ) and an adjacent stator ( ) is precisely controlled and minimized. Shutoff surfaces ( ) formed on the flywheel ( ) function as a portion of the die for injection molding of the cage ( ).

International Classification:

B63H 2032

US Classification:

440 77

Abstract:

An improved air inlet cover for use with outboard motors is disclosed. A particular embodiment of the cover is formed by a generally hollow shell having an open side. An air passage is located opposite the open side at an upper portion of the shell. A baffle extends from an upper inner portion of the shell to an elevation below the air passage and is disposed generally opposite the air passage. An exit port is provided at the bottom of the chamber for discharging water collected therein, and a valve is provided within the exit port. When the exit port is submerged the valve is closed and provides a barrier to water entry. Preferably, the cover is located at an upper forward portion of the outboard motor cowl and both the air passage and air inlet are high up on the upper forward portion.

Abstract:

A cylinder head assembly for an internal combustion engine includes a cast cylinder head, a turbocharger housing integrally cast with the cylinder head, and a water jacket cast into the integrally cast turbocharger housing and configured to receive a flow of coolant for cooling the integrally cast turbocharger housing. The assembly can also include a wastegate housing integrally cast with the cylinder head and the turbocharger housing, and a water jacket cast into the integrally cast wastegate housing. The water jacket is configured to receive a flow of coolant for cooling the integrally cast turbocharger housing and the integrally cast wastegate housing.

F02B 33/40

Abstract:

A cylinder head assembly for an internal combustion engine includes a cast cylinder head and a turbocharger housing integrally cast with the cylinder head and having an integrally cast wastegate housing. The turbocharger housing is configured to receive a turbocharger cartridge rotatably supporting a shaft coupled between a compressor wheel and a turbine wheel. The integrally cast wastegate housing defines a wastegate chamber configured to receive a wastegate valve, a flow of exhaust gas from the turbine wheel, and a flow of wastegate exhaust gas.
