Abstract:
An engine generator, wherein the effect of cooling by cooling air is improved despite the fact that devices are compactly arranged inside a housing.  An engine generator is provided with an engine (2), a generator (3), an inverter (4), a control device, a fuel tank (7), an air cleaner (16), a muffler (18), a radiator (6), and a housing (5) for containing therein the above described devices.  Cooling air introducing openings (12, 11) and a cooling air discharge opening (14) are provided in a side section of the housing (5), and a cooling air path is formed between the cooling air introducing openings and a cooling air discharge opening.  The generator (3), the inverter (4), and the air cleaner (16) are arranged in the cooling air path at a position upstream of the engine (2).  The fuel tank (7), the radiator (6), and the muffler (18) are arranged in the cooling air path at a position downstream of the engine (2).  Outside air is taken as cooling air into the housing (5) from the cooling air introducing openings (12, 11), caused to flow from the upstream toward the downstream of the cooling air path, and discharged to the outside of the housing (5) from the cooling air discharge opening (14).
