Filed:

Feb 19, 2002

Appl. No.:

10/078280

Inventors:

Alan William Hayman - Romeo MI
Gary J. Patterson - Utica MI

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F01N 300

US Classification:

60284, 60285, 60286, 60274, 123533, 123481, 123198 F

Abstract:

A vehicle engine control system controls an engine that includes a plurality of cylinders and that generates exhaust gas. An air-assisted direct injection fuel system supplies an air/fuel mixture to the cylinders. A catalytic converter reduces harmful emissions from the exhaust gas after the catalytic converter reaches a light-off temperature. A controller communicates with the engine, the catalytic converter and the air-assisted direct injection fuel system. The controller optimizes cam phasing, the air/fuel mixture and spark angle for full and partial engine operating modes. The controller deactivates at least one of the cylinders of the engine before the catalytic converter achieves the light-off temperature to hasten light-off of the catalytic converter.

International Classification:

F01N 300

US Classification:

James C. Elmslie - Oxford MI
Gary J. Patterson - Utica MI

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F02M 4100

US Classification:

123463, 123457

Abstract:

A method for extending the operating range of engine fuel injectors fed by a pressurized fuel system includes operating the fuel system at a controlled lower fuel pressure during engine operation in a lower power range, and operating the fuel system at a controlled higher fuel pressure during engine operation above the lower power range. An engine embodying the method may include a fuel distributor connected with the injectors for supplying the pressurized fuel and a pressure control operative in response to a prescribed engine condition, such as supercharger boost pressure, to maintain injector fuel supply pressure at a lower value during engine operation in a lower portion of the power range and at a higher value during engine operation in a higher portion of the power range. The dual or multiple fuel pressures provide greater fuel output for increased power in the higher power range with consistent fuel delivery for stable idle and engine operation in the lower power range.

Appl. No.:

10/672952

Inventors:

Gary J. Patterson - Utica MI, US
Alan W. Hayman - Romeo MI, US

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F01L001/34

US Classification:

123198F, 123198 DB, 123 9016

Abstract:

An internal combustion engine includes a plurality of cylinders each having intake and exhaust valves and at least one camshaft timed to operate the valves with a high performance fixed overlap. Each camshaft has a cam phaser controlled to equally vary the intake and exhaust valve timing for superior full throttle performance over the engine speed range; Valve deactivation mechanisms operate to deactivate up to half the cylinders during idle and light load operation for increasing fuel efficiency and emission control and maintaining stable operation of the operating cylinders. The engine may also be started with half the cylinders cut out and then run with stable operation in this mode during idle and light load because the increased load on the operating cylinders gives stable operation with an increased valve overlap permitting increased performance and emission control at higher load operation on all the cylinders.

Appl. No.:

10/766156

Inventors:

William C. Albertson - Clinton Township MI, US
Gary J. Patterson - Utica MI, US

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F02M025/07
F02D011/10

US Classification:

123399, 12356821, 123198 F

Abstract:

Fuel consumption in a vehicle engine is reduced by varying charge dilution in an intake manifold of the engine to maintain a pressure in the intake manifold within a predetermined range. Pumping work performed by engine cylinders is reduced, which reduces fuel consumption.

Inventors:

Richard Stephen Davis - Lake Orion MI, US
Ronald J. Herrin - Troy MI, US
Gary J. Patterson - Utica MI, US

Assignee:

GM Global Technology Operations, Inc. - Detroit MI

International Classification:

F01L 1/00

US Classification:

123 901, 123321

Abstract:

A vehicle may include a drive axle, an engine assembly, a coupling device, and an engine load management system. The engine assembly may include a valvetrain including a fixed-lobe camshaft and intake and exhaust valves supported by the engine assembly. The fixed-lobe camshaft may include a first lobe engaged with the intake valve to open the intake valve and a second lobe engaged with the exhaust valve to open the exhaust valve. The first and second lobes may be fixed relative to one another to define a constant valve overlap condition that provides for opening of the intake valve before the exhaust valve is fully closed, creating an engine operating condition that results in combustion instability below an engine load limit. The engine load management system may be in communication with the engine to prevent engine operation below the engine load limit.

Abstract:

A modular system for protecting a critical asset includes a plurality of vertical members extending vertically upwardly from a ground surface, and inner and outer stacks of spaced-apart horizontal members connected between adjacent pairs of the vertical members defining a vertical wall. The spaced-apart horizontal members have cross sections and spacings such that no line can be drawn through the wall without intersecting with one or both of the inner and outer stacks. The cross sections of the horizontal members in both stacks include elongated angled surfaces such that projectile on a trajectory toward the critical asset is deflected upwardly or downwardly and away from the critical asset. In a preferred embodiment, the horizontal members are angle irons. In a more preferred embodiment the horizontal members are 1/2″ 90-degree steel angle irons oriented sideways, such that the elongated plates making up the angle irons are 45 degrees off horizontal.
