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.:

9/354539

Inventors:

Charles Edwin Freese - Westland MI

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.

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.

Appl. No.:

9/215360

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.

Appl. No.:

9/224128

Inventors:

Charles Edwin Freese - Westland MI

Assignee:

Detroit Diesel Corporation

International Classification:

F02B 7700
F02F 700

US Classification:

123 9038

Abstract:

The rocker arm cover on a diesel engine can be formed of a rigid molded plastic material to minimize the transmission of noise into the atmosphere. Sonic vibration of the cover can be reduced by reducing the cover material stiffness. The reduced stiffness of the cover material allows the roof area of the cover to be momentarily displaced away from the cylinder head in the presence of an acoustic wave, so that the roof area is not able to develop the restoring force that is necessary for vibrational motion.

Inventors:

Charles Edwin Freese - Westland MI

Assignee:

Detroit Diesel Corporation - Detroit MI

International Classification:

F02F 700

US Classification:

123195C

Abstract:

An oil pan for an internal combustion engine includes a body defining a reservoir for collecting engine coolant. The reservoir has a bottom and side walls extending upwardly from the bottom to present a flanged lip through which the oil pan may be mounted to the engine. An oil cooler assembly is housed within the body of the oil pan for cooling lubricant received from the engine. The body includes an oil inlet passage formed integrally therewith for receiving lubricant from the engine and delivering lubricant to the oil cooler. In addition, the body also includes an oil pick up passage formed integrally therewith for providing fluid communication between the reservoir and the engine through the flanged lip.

International Classification:

F01M 910

US Classification:

123 9038

Abstract:

An internal combustion engine including an engine block having a pair of cylinder banks arranged in a V-shaped configuration such that each of the pair of cylinder banks presents a top wall disposed at an acute angle relative to the horizontal. Each cylinder bank includes a plurality of cylinders. A pair of cylinder heads are associated with each pair of cylinder banks. Each of the cylinder heads includes upper and lower walls disposed at an angle relative to each other such that each cylinder head is substantially wedge-shaped in cross-section. Each cylinder head is mounted to the engine block such that the upper wall of each cylinder head is substantially parallel to the horizontal. A pair of exhaust manifolds are mounted to each pair of cylinder heads. A single, integrated intake manifold and rocker cover is mounted to the horizontal upper wall of the pair of cylinder heads.
