An engine generator is provided having an improved cooling effect realized by cooling air while ensuring a compact arrangement of components in a housing. The engine generator includes an engine, a generator, an inverter, a control device, a fuel tank, an air cleaner, a muffler, a radiator, and a housingaccommodating the foregoing components. The engine generator includes cooling air inletsandand a cooling air outleton sides of the housingwith a cooling air passage disposed between the inlets and outlet. The generator, the inverter, and the air cleanerare disposed further upstream than the enginealong a cooling air passage. The fuel tank, the radiator, and the mufflerare disposed further downstream than the enginealong the cooling air passage. Ambient air is incorporated as cooling air into the housingthrough the cooling air inletsand, allowed to flow from an upstream toward a downstream of the cooling air passage, and discharged to outside the housingthrough the cooling air outlet

Engine generator

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.

An engine-driven generator incorporating an engine and a generator into a single unit, with the output shaft of the engine coaxially connected to the rotating shaft of the generator, via a frame structure formed by integrally combining two support members provided in parallel with the axial line of the output and rotating shafts with two handle members orthogonally intersecting the aforementioned axial line via upright members wherein base members are fixedly fitted between the support members below the engine and the generator in such a manner as to orthogonally intersecting the aforementioned support members; a generator mounting member, having a mounting hole in the axial direction, provided between a bulged portion integrally protruded on the lower part a rear bracket of the generator and a base member below the generator, and two engine mounting members provided between the engine and a base member below the engine are disposed at the apexes of a triangle, so that the engine and the generator are mounted on the frame structure via the three mounting members.
