Abstract
A four-stroke cycle internal combustion engine is adapted to deliver oil mist from an oil reservoir to a cam chamber together with blow-by gas. It has an oil reservoir, a cam chamber, an oil dipper formed on a connecting rod for agitating oil in the oil reservoir to generate oil mist, a carburetor, and an oil separator provided between the cam chamber and the carburetor and for separating oil contained in oil mist from blow-by gas. The oil separator has a vertically extending first passage which communicates with the cam chamber at an upper end and communicates with the oil reservoir at a lower end and a second passage which communicates with the lower end of the first passage at one end and communicates with a venturi of the carburetor at the other end.
