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.

Assignee:

Detroit Diesel Corporation - Detroit MI

International Classification:

F02F 142

US Classification:

1231933

Abstract:

An internal combustion engine including an engine block having a top wall and a plurality of longitudinally aligned, spaced cylinders. A cylinder head has upper and lower walls with side walls extending therebetween. The cylinder head is mounted to the engine block with the lower walls sealingly opposing the top wall of the block so as to close the open ends of the cylinders. The cylinder head includes at least four passages associated with each of the cylinders extending through the cylinder head for delivering intake air to the associated cylinder and for removing exhaust gas from the associated cylinder. Each of these passages include an inlet, an outlet in fluid communication with the associated cylinder and a flow path extending therebetween. At least one of these passages includes a boss which is recessed in the passage and aligned with the inlet and which is adapted to receive a fastener employed to clamp the cylinder head to the engine block.

Appl. No.:

8/403638

Inventors:

Charles E. Freese - Westland MI
Raymond E. Garvey - Powell TN

Assignee:

Detroit Diesel Corporation - Detroit MI

International Classification:

G01R 2726

US Classification:

324663

Abstract:

A method and apparatus for detecting the degree of deterioration of a lubricating oil for an operating machine includes a grid-like capacitive sensor that uses the lubricating oil as a dielectric medium. A magnetic field is imposed upon the oil to attract ferromagnetic wear particles into the vicinity of the sensor. Preferably, the magnetic field is generated by at least two independently controlled electromagnet windings aligned such that the magnetic field produced by each winding acts upon the wear particles. A plurality of capacitance measurements are taken at periodic intervals at each of several magnet operational states for respective classification and analysis. All windings may be simultaneously de-energized for release of captured particles back in to an oil circulation stream and to clean the capacitative sensor grid of accumulated particulates.

Inventors:

Charles E. Freese - Westland MI

Assignee:

Detroit Diesel Corporation - Detroit MI

International Classification:

F02B 3344

US Classification:

606052

Abstract:

A turbocharged V type engine can be equipped with an exhaust gas recirculation cooler integrated into the intake manifold, so as to achieve efficiency, cost reductions and space economization improvements. The cooler can take the form of a tube-shell heat exchanger that utilizes a cylindrical chamber in the air intake manifold as the heat exchanger housing. The intake manifold depends into the central space formed by the two banks of cylinders on the V type engine, such that the central space is effectively utilized for containing the manifold and cooler.
