A heat storage cover is provided in an engine room. The heat storage cover covers an engine from above and surrounds the periphery of an upper portion of the engine to internally store, through the medium of air, heat dissipated from the engine and block upward heat dissipation. The engine includes an air inlet for introducing, into a combustion chamber, high temperature air obtained by the heat storage cover blocking the upward heat dissipation.

The concave part includes an open end portion having an inner diameter greater than an outer diameter of a tip end portion of a ball stud, a fitting portion which is connected to the open end portion and has an inlet smaller than the outer diameter of the tip end portion and in which the tip end portion is housed, and a plurality of slits which are formed in a fitting direction of the ball stud from the open end portion and arranged at a predetermined interval along the circumference of the concave part. The pull-out prevention part includes a plurality of first ribs located on extensions of the respective slits.

A co-curable thermoset acoustic liner and method of forming the same includes a sound attenuating core having a plurality of core cells. An inner face sheet having a plurality of face sheet apertures is coupled to the core by an inner thermoset adhesive sheet, which has a plurality of adhesive sheet apertures. Each of the plurality of adhesive sheet apertures is aligned within a corresponding one of the plurality of face sheet apertures so that the plurality of core cells are placed in fluid communication with airflow over the inner face sheet to create a Single Degree of Freedom (SDOF) acoustic liner.

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.
