The purpose of the present invention is to improve cooling efficiency of a cylinder head of an air-cooled engine. With regard to the construction that a cooling fan is provided at one of ends of a crankshaft, and cooling air from the cooling fan is guided to a cylinder headso as to cool the cylinder head, an intake manifoldis arranged above the cooling fan, a ductis provided at the lateral center of the intake manifoldso as to suck air from an air cleaner, cooling air is sent from both sides of the ductto an intake valve, an exhaust valve and an injection nozzle arranged in the cylinder head, and a shielding plateis provided at one of lateral sides of the duct

Engine

A governor device comprises a first lever connecting a governor lever to a rotary speed setting lever interlockingly, a second lever pivotally supported by the first lever, and a third lever pivotally supported by the second lever, regulated its rotation amount by the second lever and interlocked with a governor weight. A fuel injection compensation spring is provided between the first lever and the second lever so as to bias them for decreasing the rotary speed for a fixed amount at the time of low speed rotation. A compensation starting rotary speed setting device, which is a set load changing means for the fuel injection compensation spring, is provided on the first lever near the fuel injection compensation spring.

Governor device

The present invention provides an engine cover structure for an engine () whose cylinder head () is covered at three of front, rear, right and left sides thereof by a fuel tank (), an air cleaner () and a muffler (), respectively, comprising a cover () which covers the remaining one side and/or a top side of the cylinder head ().

Cover structure for engine

With regard to a construction that a fanis provided at one side of an engineand covered by a fan casing, and an air cleaneris arranged near the fan casingand at a side of a cylinder headon which an intake portis disposed, a suction portcommunicated with the inside of the fan casingis provided in a main bodyof the air cleaner. A barrieris provided at a position facing to the suction portin the air cleaner. A wall standing toward the fan casingand the cylinder headis formed on the outer surface of the main bodyof the air cleaner. An air intake part is provided on one of side surfaces of a cover bodyof the air cleanerand the cover bodyis constructed to be an equilateral polygon. An intake pipecommunicating the air cleanerwith the intake portof the cylinder headis constructed integrally with a main bodyof the air cleaner

A blow-off duct is rotatably mounted on an air-conditioner. A human body detection device is provided at the blow-off duct in order to detect the presence of a person to be air-conditioned and then to identify the moving direction thereof. Comfortable localized air-conditioning can be realized since a wind direction control device controls a duct drive device of the blow-off duct in response to a human body detected signal and movement signal outputted by the human body detection device, and thus rotating the blow-off duct in accordance with the movement of the person to be air-conditioned.
