Abstract
Official abstract text for this publication.
Provided is a general purpose engine having a sufficient cooling function. The general purpose engine 1 comprises: an engine main body 10 having a canister muffler 132 on the side thereof; a cooling mechanism 9 that cools the engine main body 10 ; and a shroud 4 covering the engine main body 10 and the cooling mechanism 9 . The cooling mechanism 9 comprises: a cooling fan 90 that generates cooling air by rotating; and a blowing unit 92 that blows cooling air generated by the rotation of the cooling fan 90 , towards the upper section of the engine main body 10 . A space S in which the cooling air blown from the blowing unit 92 towards the upper section of the engine main body 10 can flow vertically downwards is formed between the shroud 4 and the canister muffler 132 . A return section 40 that guides the cooling air towards a stud bolt 132 a that fixes the canister muffler 132 to the engine main body 10 is formed on an inside wall surface of the shroud 4 forming the space S.
