Abstract: 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.

Abstract: 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.
