Abstract
In an engine-driven power generation apparatus, where an engine and a power generator driven by the engine are accommodated in a hermetically sealed housing and where an external air take-in pipe takes air into the housing, an air discharge pipe discharges the taken-in air to outside of the housing and an engine exhaust pipe discharges exhaust gas to outside of the housing, an ejector chamber is provided outside of the housing for causing the air, flowing in the air discharge pipe, to be compulsorily sucked to outside of the housing through a sucking action of the exhaust gas flowing in the engine exhaust pipe.
Claims4
An engine-driven power generation apparatus comprising:
- an engine and a power generator accommodated in a hermetically sealed housing, the power generator being driven by the engine to generate electric power;
- an external air take-in pipe for taking air into the housing from outside the housing, the power generator being cooled by the air taken in through the external air take-in pipe, a part of the taken-in air, having cooled the power generator, being used as combustion air for the engine;
- an air discharge pipe having an upstream end portion inserted in the housing for discharging a remaining part of the taken-in air, having cooled the power generator, to outside of the housing;
- an engine exhaust pipe for discharging exhaust gas of the engine from the engine to outside of the housing;
- and
- an ejector chamber provided outside of the hermetically sealed housing for causing the air, flowing in the air discharge pipe, to be compulsorily sucked to outside of the housing through a sucking action of the exhaust gas flowing in the engine exhaust pipe in a direction from the engine toward outside of the housing.
