Filed:

Jun 3, 2005

Appl. No.:

11/144251

Inventors:

David Lancaster - Troy MI, US
James Solomon - Grosse Pointe Woods MI, US

International Classification:

F16H 7/08
F16H 7/12
F16H 7/22

US Classification:

474110000, 474133000, 474109000

Abstract:

The present invention provides an automotive accessory drive system and method having a selectively lockable flexible drive belt tensioner with a damper element filled with a variable viscosity fluid with magneto-rheological or electro-rheological properties. When the combined alternator/starter motor of a belt alternator starter (BAS) system is commanded to restart the engine, the locked flexible drive belt tensioner will apply force to the normally slack side of the flexible drive belt, thereby maintaining frictional engagement between the flexible drive belt and the drive and driven pulleys. Upon engine restart, the tensioner will unlock and resume normal operation.

James G. Solomon - Grosse Pointe Woods MI
Robert A. Bolton - Rochester MI
Albert A. Miller - Warren MI
Cletus R. Abke - East Detroit MI

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F01P 314

US Classification:

123 4178

Abstract:

A two stroke cycle engine has tiered cooling jackets in the cylinder block with upper and lower jackets separated by a diaphragm wall. Transfer openings in the diaphragm and downward portions of the lower jacket direct coolant flow around exhaust ports and preferentially along the exhaust port side of the engine cylinder openings. A cylinder head gasket controls outflow from the upper jacket to the cylinder head through transfer holes placed preferably on the exhaust side of the upper jacket to provide overall control of flow in the cooling jacket system.

Appl. No.:

7/369224

Inventors:

James G. Solomon - Grosse Pointe Woods MI
Chester J. Rivard - Sterling Heights MI

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F01P 104

US Classification:

123 4139

Abstract:

A two cycle engine has oil distribution means through the cylinder wall to feed internal oil passages in the associated piston that distribute oil directly to the skirt and cylinder walls, preferably between ports, and/or to the wrist pin and connecting rod bearing to thereby limit oil carryover into the engine charging and scavenging air.

Appl. No.:

7/369220

Inventors:

Ronald J. Cantrell - Belleville MI

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F02B 7502

US Classification:

123 65BA

Abstract:

A port scavenged two cycle engine with a separate source of pressurized air has a valve between each port and the air supply to provide a high blowdown pulsing scavenging flow to the cylinders similar to that of a crankcase scavenged engine. Various arrangements with additional features are disclosed.
