Air-cooled engine for working machine

摘要

An air-cooled engine (20) for a working machine includes a fan cover (35), a muffler protector (36), and an insulator (37). The fan cover has a guide opening for guiding a cooling air toward an exhaust muffler (27). The muffler protector has air discharge holes (86, 86) for discharging the cooling air, which has been introduced through the guide opening into a guide passage, in a direction away from the working machine. The insulator has a deflector section (37) bent toward a carburetor (29) so that the cooling air having passed through another guide passage between the insulator and a cylinder barrel (22) is guided by the deflector section in a direction away from the working machine.
