Appl. No.:

11/803402

Inventors:

Andrew N. Mcgilvray - East Peoria IL, US
John T. Vachon - Peoria IL, US
William E. Moser - Peoria IL, US

Assignee:

Caterpillar Inc. - Peoria IL

International Classification:

F02F 1/42

US Classification:

1231935, 123 4182 R

Abstract:

An internal combustion engine that includes a block, a cylinder head having an intake valve port and exhaust valve port formed therein, a piston, and a combustion chamber defined by the block, the piston, and the head. At least one thermoelectric device is positioned within either or both the intake valve port and the exhaust valve port. Each of the valves is configured to move within a respective intake and exhaust valve port thereby causing said valves to engage the thermoelectric devices resulting in heat transfer from the valves to the thermoelectric devices. The intake valve port and exhaust valve port are configured to fluidly direct intake air and exhaust gas, respectively, into the combustion chamber and the thermoelectric device is positioned within the intake valve port, and exhaust valve port, such that the thermoelectric device is in contact with the intake air and exhaust gas.

International Classification:

G06F 9/455

US Classification:

703 9, 13756519, 73168

Abstract:

Methods and systems provide a simulation of cavitation damage. In one implementation, a computer-implemented method simulates a potential for cavitation damage. According to the method, data defining a modeled component is imported to a flow solver tool. The flow solver tool simulates a liquid that flows through the modeled component. Voids created by the flow of the liquid cause a plurality of vapor implosion pressure events. The method further includes displaying a histogram showing a portion of the modeled component. On the histogram, locations of the plurality of vapor implosion pressure events are visually distinguishable on a surface of the portion of the modeled component.

US Classification:

134 40, 134 42

Abstract:

Method of Using an Anti-Stick Coating to Reduce Dirt Accumulation The present disclosure is directed to a method of reducing dirt buildup on a machine surface. The method involves applying a sacrificial layer of an oil-based liquid on the surface and allowing dirt accumulation on the surface. The accumulated dirt along with the oil-based liquid is then removed.

US Classification:

1231935, 123 4182 R

Abstract:

In one particular embodiment, an internal combustion engine is provided. The engine comprises a block, a head, a piston, a combustion chamber defined by the block, the piston, and the head, and at least one thermoelectric device positioned between the combustion chamber and the head. In this particular embodiment, the thermoelectric device is in direct contact with the combustion chamber. In another particular embodiment, a cylinder head configured to sit atop a cylinder bank of an internal combustion engine is provided. The cylinder head comprises a cooling channel configured to receive cooling fluid, valve seats configured for receiving intake and exhaust valves, and thermoelectric devices positioned around the valve seats.
