Abstract

An air-cooled general-purpose engine includes: a cooling fan fixed to one end portion, protruding outward from one end wall of an engine main body, of a crankshaft; and a shroud which is mounted to the engine main body, and which defines a cooling-air path between the shroud and the one end wall, the cooling-air path guiding a cooling air blown under pressure from the cooling fan. The air-cooled general-purpose engine includes: an oil pump which pumps up an oil from an oil reservoir; and an oil-supply path which is formed in the one end wall, facing the cooling-air path, of the engine main body, and configured to guide the oil discharged from the oil pump to a valve operating chamber in a head portion of the engine main body, and a jet for jetting the oil is provided in an opening of the oil-supply path, the opening being open to the valve operating chamber. Accordingly, it is possible to be excellent in cooling oil and to preferably lubricate a valve operating system in addition to the surrounding of a crankshaft.
