    Abstract: Systems, methods and apparatus for noise attenuation of a generator set are disclosed. The generator set includes an internal combustion engine enclosed within a compartment that substantially isolates the internal combustion from ambient air and a load connected to the internal combustion engine. A heat exchanger is disposed within or coupled to the compartment and is operable to cool air in the compartment without directly exchanging ambient air with compartment air.

    Abstract: A working machine includes an engine compartment, an engine hood, an internal combustion engine arranged in the engine compartment and an exhaust system, which extends from the engine out of the engine compartment via the engine hood. The exhaust system is provided with an air intake for admitting air from the engine compartment into the exhaust system and entraining the air together with the exhaust gases. The air intake includes an air baffle element, which leads the air into an essentially central area in an outlet duct, in which the exhaust gases are led out, in such a way that the air is entrained out of the engine compartment by the exhaust gases through an ejector effect which the exhaust gases exert on the air in the outlet duct.

    Abstract: A marine propulsion device (12) including a sleeve (32) formed around an exhaust conduit (26) to form an air cooling passage (34) there between. Cooling air (38) is moved through the cooling passage (34) by an active fan (42) and/or a passive venturi (56). Cooling air (38) is drawn from within an engine compartment (24) for a predetermined time before and after the engine (16) is operated. A water-cooled discharge support (70) is located above the waterline (28), thereby preventing the intermixing of exhaust gasses (36) with the environmental water (27).

    Abstract: A negative pressure air stream accelerator for a suction type air cooling mechanism for cooling an internal combustion engine produces negative pressure by accelerating the exhaust gas stream to form a strong negative pressure connected to the cooling device to draw cooling air therethrough, and accelerates the velocity of the exhaust gas by providing at least one stage of acceleration units for throttling by a reduced cross-sectional area of the exhaust gas passage having an outer casing connected to the cooling device, the accelerator having holes through the walls thereof communicating with the interior of the casing. A plurality of stages are provided in series for utilizing the air stream accelerated to a high velocity at the final negative pressure stream.
