摘要： A four-stroke cycle internal combustion engine comprises a connecting rod which has an oil dipper at a big-end thereof, a crankcase, a partition wall which surrounds the connecting rod to provide a separation between the crankcase and an oil reservoir and an outer wall which is outward of and surrounds the partition wall and is connected to the partition wall at upper ends thereof so as to define the oil reservoir below the crankcase. A slit is formed in the partition wall below the connecting rod to allow the oil dipper to protrude into and be withdrawn from the oil reservoir to splash oil in the oil reservoir for lubrication by the oil dipper through a swinging motion of the connecting rod. The depth of the oil reservoir is shallower at least in a part of an outer edge area thereof than that below the oil dipper so that a tip of the oil dipper reaches the oil level even when the oil flows into the outer edge area of the oil reservoir.

摘要： An internal combustion engine capable of optimizing the amount of oil in the crank chamber with a simplified structure of lubrication system, in which a U-shaped oil reservoir is formed surrounding and adjacent to a crank chamber. At least one small hole is formed on a partition wall which separates the oil reservoir and the crank chamber from each other so that the crank chamber may always communicate with the oil reservoir through the small hole. Due to a flow resistance in the small hole, a pressure Po in the oil reservoir changes following a change of pressure Pc in the crank chamber with some delay, and where the pressure difference between the oil reservoir and the crank chamber caused by a delay in the change of the pressure Po in the oil reservoir, results in the introduction of the oil in the oil reservoir into the crank chamber. It further allows excessive oil in the crank chamber to be circulated back into the oil reservoir.

摘要： A four-stroke cycle internal combustion engine in which an oil reservoir for storing lubricating oil is arranged below a crank chamber housing a crankshaft, and oil mist formed in the oil reservoir is supplied to the interior of the crank chamber and to a valve chamber through an oil mist passage for providing fluid communication between the oil reservoir and the valve chamber. The oil mist passage includes a pre-separation oil mist passage section formed in the crankshaft, a cylindrical centrifugal-separation chamber surrounding the outer-periphery of the crankshaft, a post-separation oil mist passage section extending from the centrifugal-separation chamber in the opposite direction of the rotational direction of the crankshaft and in fluid communication with the valve chamber, and an oil return passage providing fluid communication between the centrifugal-separation chamber and the oil reservoir.

摘要： An object of the present invention is to provide an improved lubricating method and device for the internal combustion engine, which allows the engine to be lubricated by taking advantage of engine vibration without using other power source. The lubricating device includes a crankcase separated into a crank chamber and an oil reservoir by a partition wall. The partition wall has an opening provided with a wire net for covering the opening. A coil spring is suspended within the oil reservoir so as to form a U-shape. During operation, an engine vibration induces a vibration of the coil spring, and the oscillating coil spring agitates and/or splashes up an engine oil contained in the oil reservoir, and whereby an entire oil surface is ruffled. The engine oil introduced into the crank chamber impinges on a crankshaft and finer droplets or oil mist is formed to thereby lubricate the crankshaft and other engine components.
