Abstract: In one aspect a method for lubricating a tribosystem is provided that may include providing a new tribosystem including at least two solid surfaces that interact during operation of the tribosystem and providing lubrication oil for lubricating the tribosystem. The method may further include operating the tribosystem while lubricating the tribosystem with the lubrication oil during an initial period and supplying anti-wear additives to the lubrication oil at the end of the initial period. In another aspect a lubrication assembly for containing lubrication oil may be provided. The lubrication assembly may include an anti-wear additive storage and a releaser that is configured for releasing anti-wear additive from the anti-wear additive storage into the lubrication oil after an initial period of operation.

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.

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.
