Systems and apparatuses include an apparatus including an intake defined by an intake aperture, an intake baffle, and an intake floor structured to couple to an intake portion of an enclosure roof, the intake extending along at least eighty percent (80%) of a width of the apparatus on a first side, an exhaust defined by an exhaust aperture, an exhaust baffle, and an exhaust floor structured to couple to an exhaust portion of the enclosure roof, the exhaust extending along at least eighty percent (80%) of the width of the apparatus on a second side opposite the first side, a partition panel isolating the intake from the exhaust, and an engagement mechanism structured to couple the apparatus to a generator set.

Low noise enclosure

An internal combustion engine is coupled to an electric power generator. An exhaust manifold for the engine includes an exhaust gas conduit. A housing includes a catalyst in fluid communication with the conduit to receive exhaust produced by the engine. The catalyst is operable to reduce one or more constituents of the exhaust.

An electrically controlled actuator includes a rotor detachably mounted on a rotating shaft, and a stator disposed around the rotor. A fluid flow plate is mounted on the rotating shaft and opens/closes a fluid passageway. A spiral spring is mounted on one end of the rotating shaft. When the rotor is rotated, the fluid flow plate regulates a fluid flow in the fluid passageway. An electrical control current is received in the actuator and is converted to a magnetic torque to rotate the rotor, while the spiral spring is increased in tension. The spiral spring opposes the rotation of the rotor so as to control the position of the fluid flow plate. The rotor includes two symmetric tips extended from two curved outer surfaces at two leading edges of the rotor. An air gap is defined between the inner surfaces of the stator and the outer surfaces of the rotor. The air gap becomes narrower when the rotor is rotated into a space between two poles of the stator.
