Abstract: 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.

Abstract: Disclosed is a piston cooling device wherein the cooling efficiency of a piston is improved by oil injected from an oil jet and supplied to a cooling passage provided in the piston, and the amount of cooling oil is reduced when an internal combustion engine is operated at maximum output. The piston cooling device is provided with a piston for an internal combustion engine, in which a circumferential passage and a cooling passage having an inlet passage and an outlet passage are provided, and an oil jet for injecting oil from an injection port to the inlet passage. The oil jet injects oil at every stroke of the piston so that a two-phase plug flow composed of gas and oil is formed in the cooling passage at least when an internal combustion engine is operated at maximum output.

Abstract: A rotatable member (40) such as a sprocket is rotatably mounted on a fixed shaft member (32), and a first oil passage (72) extending in a radial direction is formed by a thrust member (36) abutting an axial end surface of the rotating member. The inner end of the first oil passage communicates with a radial bearing interface (A) of the rotatable member, and an oil jet ejected from an orifice (68) of an oil nozzle (66) is directed to an open outer end of the first lubricating oil passage. Because the first oil passage is fixed in position, the radial bearing interface receives an adequate supply of lubricating oil fed from the oil nozzle. The other axial end of the rotating member may be provided with a second lubricating oil passage (82) which also extends in a radial direction, the second lubricating oil passage having an open outer end and an open inner end communicating with the radial bearing interface. The centrifugal force acting on the lubricating oil in the second lubricating oil passage promotes a favorable re-circulation of the lubricating oil, and hence a favorable lubrication.

The four-cycle engine has a lightweight aluminum alloy engine block having a cylindrical bore and an enclosed oil reservoir formed therein. A vertical or horizontal crankshaft is rotatably mounted in the engine block for rotation about a crankshaft axis. A piston reciprocates within the bore and is connected to the crankshaft by a connecting rod. A trochoid or screw oil pump is driven by the camshaft connected with a cam gear, which mates with a crank gear that is driven by the crankshaft, inhales the oil from the oil reservoir to splash lubricate into the cylinder bore and valve chamber. The engine is provided with a cylinder head assembly defining a compact combustion chamber having a pair of overhead intake and exhaust ports and cooperating intake and exhaust valves. A commonality of parts between the horizontal and the vertical engine is highly achieved.

Abstract: There is provided an engine in which sliding surfaces of a cylinder and a piston do not tend to seize and the ratio of a lubricating oil to a composite fuel can be reduced. There is also provided a piston that allows the lubricating oil to be intentionally supplied to the surface of the piston that slides along the cylinder or a cylinder liner. In an aspect of the present invention, an engine in which an air-fuel mixture containing a lubricating oil is supplied into a combustion chamber includes supply means for supplying the air-fuel mixture to the interface between an inner wall of a cylinder or a cylinder liner and a tubular portion of a piston (portion between piston rings and/or piston ring portion). The supply means is, for example, through holes passing through the tubular portion of the piston and groove portions.
