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.

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.

Abstract: 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.

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.
