An air-cooled enclosure for an engine, fan and heat exchanger installation with the engine including an exhaust pipe extending outwardly through the enclosure. An engine compartment within the enclosure has an air inlet and an air outlet and an ejector utilizing the flow of engine exhaust gas from the exhaust pipe to create a low pressure within the air outlet in order to draw ambient cooling air through the air inlet into the engine compartment and out of the air outlet with a minimum of noise transmission through the enclosure. The enclosure further includes a separate engine heat exchanger and fan compartment providing a separate air inlet passage and a separate air outlet passage wherein the powered fan draws ambient cooling air into the separate air inlet and forces it through the heat exchanger and out of the separate air outlet at a minimum noise level and with optimum engine cooling effectiveness. |
