A portable generator includes a metal shroud surrounding at least a crankcase and a cylinder block of an engine. The engine is directly mounted to the shroud. The shroud forms an effective radiating element and gives an additional heat-radiating surface to the engine, thereby increasing the heat radiation capacity of the engine. Heat generated from the engine while running can, therefore, be radiated efficiently. The shroud is mounted within a sound insulating case, so that the portable generator has a double sound-insulating structure. The noise-proofing property of the portable generator is, therefore, very high.

Portable generator

A portable generator comprises a shroud for covering at least a crankcase and a cylinder block of an engine thereof. The shroud is formed of split halves. The engine is fixed to the shroud having its upper part connected to a carrying handle of a sound insulating case. As a result, the load of the engine is applied to the carrying handle through the shroud when the portable generator is lifted up with a hand. It is thus not necessary to increase rigidity of the case, thereby enabling lightening of the case. The generator arrangement also provides an improved soundproof effect since the engine, a source of noise, is covered with the shroud and the sound insulating case.

An engine generator includes an engine having an intake device and an exhaust device which are connected to an engine body, a generator connected to the engine, and a fuel tank for supplying fuel to the engine. The engine, the generator and the fuel tank are mounted on a frame. In this engine generator, the intake device and the exhaust device are connected to an upper portion of the engine body having a cylinder axis extending vertically to protrude to opposite sides from the engine body, and the fuel tank is disposed sideways of the engine body and the generator below the intake device or the exhaust device. Thus, when a vertical engine is used, the fuel tank can be effectively disposed to avoid the production of a wasteful space, thereby providing reductions in size, weight and cost.
