摘要： 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 132a 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.

摘要： An internal combustion engine (1) having a cylinder (5) having a rearwardly slanted axial line is provided with a plurality of cylindrical cyclone dust collection units (34) commonly connected to an upstream end of a filter dust collection unit (35). Each cyclone dust collection unit includes a main body (44, 45) internally defining a separation chamber (45C), and having an air inlet (31) communicating with outside and an air outlet (73) communicating with the filter dust collection unit, and the separation chamber is provided with a dust ejection hole (45D) directed tangentially in an obliquely forward direction. Thereby, dust ejected from the dust ejection hole is ejected away from the operator of the engine, and is prevented from depositing on the engine.
