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.

Engine-operated machine

A soundproof engine-operated machine or generator includes a floor having first and second air discharge hole, wall members cooperating with the floor in defining a container, at least one wall member having an air inlet for introducing air into the container, a water-cooled engine disposed in the container, a first cooling fan disposed in front of said engine for delivering air from said air inlet toward said engine to cool the engine, a machine unit such as a generator operable by the water-cooled engine, a radiator attached to the engine, a second cooling fan disposed in front of the radiator for drawing air from behind the radiator therethrough, an exhaust pipe connected to the engine and extending below the floor, a muffler connected to a downstream portion of the exhaust pipe and disposed below the floor, a duct for guiding air from the engine around the exhaust pipe to cool the exhaust pipe and for discharging the air through the first air discharge hole, and a scroll-shaped fan cover for discharging air from the radiator through the second air discharge hole to cool the muffler positioned below the second air discharge hole.
