US Patent:

20070056281, Mar 15, 2007

Filed:

Apr 12, 2006

Appl. No.:

11/402614

Inventors:

Gary Arvan - Rochester Hills MI, US
Charles Freese - Ira Township MI, US

International Classification:

F02B 33/44

US Classification:

060598000, 060605100

Abstract:

An internal combustion engine has a first and a second cylinder bank. The first and second cylinder banks are arranged such that they have less than a 180 degree included angle with respect to one another, thereby forming an inboard region or generally V-shaped cavity. A respective first and second cylinder head is mounted with respect to the first and second cylinder bank. Integrated within the first and second cylinder head is a first and second integrated exhaust manifold, respectively. The first and second integrated exhaust manifolds are provided on the engine in an “inboard” orientation, i.e. disposed on a side of their respective cylinder heads such that they are substantially adjacent to the generally V-shaped cavity. The first and second integrated exhaust manifold may operate to convey exhaust gases from the engine to at least one turbocharger, which is mounted substantially within the generally V-shaped cavity.

Appl. No.:

11/561034

Inventors:

Charles E. Freese V - Ira Township MI, US

International Classification:

F02B 33/44

US Classification:

606052, 60604

Abstract:

An engine including an exhaust system operable to convey exhaust gases from the engine. A turbocharger is in fluid communication with the exhaust system. A diesel particulate filter, disposed in fluid communication with the exhaust system and located in downstream relation to the turbocharger, operates to substantially remove particulate matter from within the exhaust gases. An exhaust gas recirculation passage, disposed in upstream relation from the turbocharger and diesel particulate filter, operates to communicate a portion of the exhaust gases to an air-to-air heat exchanger, which operates to cool the portion of the exhaust gases. An exhaust gas recirculation valve operates to selectively and variably communicate the portion of the exhaust gases to an inlet air duct of an intake system. An engine cover defines an opening operable to communicate ambient air to the air-to-air heat exchanger to promote the cooling of the portion of the exhaust gases.

Appl. No.:

12/144690

Inventors:

Charles E. Freese V - Ira Township MI, US

Assignee:

GM GLOBAL TECHNOLOGY OPERATIONS, INC. - Detroit MI

International Classification:

F02M 31/20

US Classification:

12356812

Abstract:

An exhaust gas recirculation cooler may include a housing and a first wall. The housing may include an exhaust gas region, a coolant region, an exhaust gas inlet, and an exhaust gas outlet. The first wall may be fixed within the housing and may separate the exhaust gas region from the coolant region. The first wall may include a first region facing the exhaust gas region and a first tab having a fixed end coupled to the first region and a free end generally opposite the fixed end. The free end may be displaceable between first and second positions based on an operating temperature of the exhaust gas. The free end may be displaced in a direction generally perpendicular to the first region when in the second position.

US Classification:

180167, 701 37

Abstract:

An automatic docking system for docking a towing vehicle with a towed vehicle includes a sensing device, a controller, an automatic steering system, an automatic braking system, and a plurality of targets. The sensing device detects the plurality of targets located on a hitch of the towed vehicle. The controller determines the location of the towing vehicle relative to the towed vehicle based on the detection of the plurality of targets. The controller automatically steers the towing vehicle towards the towed vehicle to assist in the docking of the towing vehicle to the towed vehicle. The controller engages the automatic braking system to slow or stop the towing vehicle as required.
