摘要： Muffler connected to the exhaust-discharging end of an engine is positioned above the engine adjacent a fuel tank. Heat blocking cover covers top and side portions of the muffler, and a fan cover, generally in the shape of a cylinder and extending close to the engine, covers an electric-power generator. Cooling fan device is provided in a cooling-air inlet portion of the fan cover for introducing cooling air from the outside to the electric-power generator covered with the fan cover. Engine-cooling air passage having a cooling-air inlet portion that faces a cooling-air outlet portion of the fan cover is provided to cool an outer surface of the engine by the cooling air flowing out through the cooling-air outlet portion of the fan cover. The engine-cooling air passage is branched upward to provide a separate muffler-cooling air passage extending between the muffler and the heat blocking cover above the engine. Thus, the cooling air introduced from the outside is allowed to cool both the engine and the muffler after having cooled the electric-power generator. With such arrangements, the engine, generator and muffler can be cooled with enhanced efficiency in a very simple manner.

摘要： An engine operated working machine includes an engine and a working machine to be driven by the engine surrounded by a soundproof case. An exhaust compartment housing a muffler is formed in the soundproof case. An exhaust pipe connected with the muffler is bent in a direction so as to direct exhaust gas discharged therefrom away from an exhaust air opening of the exhaust compartment and has an opening positioned apart from the exhaust air opening. Cooling air forced into the exhaust compartment flows around the muffler and the exhaust pipe to cool them. Exhaust gas discharged from the exhaust pipe into the exhaust compartment is mixed with the cooling air to change a discharging direction thereof and is then discharged outside of the soundproof case through the exhaust air opening.

摘要： In an engine generator unit, a framework has vertical pipe frame portions at its four corners, and an engine and an electric-power generator to be driven by the engine are provided coaxially in a direction of an engine output shaft within a space defined by the framework. Fuel tank is provided above the engine and electric-power generator between a pair of support members each spanning between a different pair of the vertical pipe frame portions. Muffler connected to an exhaust-discharging end of the engine is positioned adjacent the fuel tank in a side-by-side relation to the fuel tank. Heat blocking cover covers top and side portions of the muffler and is placed between the pair of support members in such a way that a substantially entire top region of the space defined by the framework is covered with the fuel tank and the heat blocking cover. Thus, it is possible to increase the capacity of the muffler while providing for a large capacity of the fuel tank.

摘要： In an engine generator unit, an engine is connected with an outer-rotor/magnet type generator that has a cantilevered outer rotor functioning also as a substitute for an engine fly wheel. Cooling fan device is attached to the outer rotor. The generator and cooling fan device are covered with a fain cover that is made of die-cast aluminum alloy. The fan cover has, at its one end remote from the engine, a cooling-air inlet portion for introducing cooling air from the outside via the cooling fan device, and a recoil starter is attached to the cooling-air inlet portion. Also, the fan cover is connected at its other end to the engine with a gap formed therebetween for blowing the cooling air onto an outer peripheral surface of the engine. Supporting leg members are secured to the fan cover and engine, and these leg members are also mounted to a framework via shock-absorbing members.

摘要： An engine-operated machine such as an electric generator includes a box-shaped casing, an engine disposed in an upper portion of the casing, a machine unit disposed in a lower portion of the casing, and a power transmission assembly by which the engine is operatively connected to the machine unit. The box-shaped casing includes a casing body having front and rear openings, a pair of upper doors mounted on the casing body for opening and closing upper portions of the front and rear openings, respectively, a pair of lower doors mounted on the casing body below the upper doors for opening and closing lower portions of the front and rear openings, respectively, independently of the upper doors, and a pair of screen doors mounted on the casing body inwardly of the lower doors, respectively, for opening and closing the lower portions of the front and rear openings, respectively. A fuel tank is slidably removably disposed in the casing adjacent to the machine unit. When in operation, the upper and screen doors are closed and the lower doors are open. The closed screen doors protect the internal mechanism from being tampered with or other forms of attack. The engine-operated machine is of a small height, highly compact, and small in size.
