    摘要： The present invention relates to a four-stroke cycle internal combustion engine in which lubrication oil is atomized to generate oil mist so as to lubricate an internal mechanism of the engine with the oil mist. The four-stroke cycle internal combustion engine includes an oil-mist breather in fluid communication with a fuel tank of the engine. Any oil mist remaining after the lubrication of the internal mechanism is discharged into the fuel tank 14 through the oil-mist breather 22. Since no oil mist remains in the oil-mist breather the air filter of the engine is not contained by the oil mist.

    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.
