A system in an engine is provided. The system includes a piston spraying conduit including an inlet in fluidic communication with an oil reservoir, a nozzle in fluidic communication with the piston spraying conduit, the nozzle directing an oil spray toward an exterior surface of a piston positioned within a combustion chamber, and a heat pipe transferring heat from an evaporator section to the condenser section, the evaporator section coupled to the piston spraying conduit. In this way, more effective piston cooling is provided while maintaining lubrication effectiveness.

System with a heat pipe

Systems and methods for delivering oil to an engine are provided herein. According to one embodiment, the oil delivery system includes an oil supply, a feeder passage fluidically coupled to the oil supply and a cylinder head, the feeder passage coupled to a pump and a filter positioned downstream from the pump. The oil delivery system further includes a squirter passage in fluidic communication with a plurality of piston squirters and the feeder passage at a position between the pump and the filter. In this way, less-filtered oil is selectively routed through a cooling circuit to reduce engine warm-up time.

Oil delivery system

The present invention comprises an oil system for supplying and controlling oil flow in an internal combustion engine having a variable camshaft timing (VCT) device, comprising a pressurized oil supply providing lubricating oil to the engine and the variable cam timing device and an oil circuit connecting the oil pump with the VCT and a main oil gallery of the engine via a valve apparatus. The valve apparatus responds to oil pressure near the outlet of the oil pump so that oil flows to the main oil gallery when oil pressure is above a predetermined pressure. When the VCT requests oil flow, oil pressure in the system drops. If the pressure drops below the predetermined pressure, the valve apparatus causes a reduction in flow to the main gallery.
