造であり、それぞれ騒音減衰効果は確保される。 An automobile engine consists of an engine body and engine auxiliary equipment such as an injection pump, an oil filter, a generator, and a starter. Various devices have been devised to attenuate the noise caused by these operating operations, particularly from the engine body.
For example, the engine body may be housed in a sealed soundproof box, or the entire outer surface may be covered with soundproofing material, both of which ensure the noise attenuation effect.

複雑な形状であるから、外表面を防音材で覆うに
は手間がかかり、コストに悪影響を与える。 However, since the engine body requires maintenance, a partial door body must be provided in the soundproof box, making the structure complicated. Further, since the engine auxiliary equipment is arranged around the engine body, it is difficult to position the door body, and maintenance is troublesome. Furthermore, since the engine body has a complex shape due to its structure, it takes time and effort to cover the outer surface with a soundproofing material, which has a negative impact on cost.

びエンジン補機６と離間対向する。 Hereinafter, one embodiment of the present invention will be described based on the drawings. Reference numeral 1 in FIG. 1 is an engine body, which is composed of a cylinder block 2, a cylinder bed 3, an intake manifold 4, an exhaust manifold 5, and the like. Engine auxiliary equipment 6 is disposed on both sides of the engine body 1, especially on both sides of the silling block 2. This engine auxiliary machine 6 is a shilling block 2
It consists of an injection pump 7 and an oil filter 8 arranged on one side, and a generator 9 and a starter 10 arranged on the other side. In addition, the engine auxiliary machine 6 includes mechanical parts not shown. Further, upper and lower stays 11a, 11a, 11b, and 11b protrude horizontally from the upper and lower portions of both side surfaces of the engine body 1. Both stays 11a and 11b are provided so as to protrude to the outside of the engine auxiliary machine 6.
The soundproof covers 12, 12 are rotatably supported above each surface and across the ends of the lower stays 11a, 11b. That is, the lower end of the soundproof cover 12 is rotatably attached to the protruding end of the lower stay 11b via the hinge 13. Upper stay 11
As shown in FIG. 2, the upper end of the soundproof cover 12 is removably supported on the protruding end of the soundproof cover 12 via a fixing member 14 consisting of a bolt and a nut. Note that the base ends of both the upper and lower stays 11a and 11b are connected to the engine body 1 through an elastic material 15, as shown in the figure.
It is recommended to install it on the The soundproof cover 12 faces the engine main body 1 and the engine auxiliary equipment 6 at its upper, lower end, and both sides at a distance.

用いられる。 Furthermore, to explain the soundproof cover 12,
This has a triple structure in which the outermost part is a damping steel plate 16, the innermost part is a layered sound absorbing material 17, and the innermost part is a sound absorbing material cover 18. The above vibration damping steel plate 1
6, for example, as shown in FIG. 3A, a polymer film material 20 is mounted between two thin steel plates 19, 19. Alternatively, as shown in FIG. B, one side of the steel plate 21 may be coated with a polymeric material 22 such as unsaturated polyester, epoxy resin, or rubber material. The sound absorbing material cover 17 is supported by a holder 23 provided on the damping steel plate 16 at its upper and lower ends. The sound absorbing material 17 is interposed between the damping steel plate 16 and the sound absorbing material cover 18, and is made of, for example, urethane foam.
しかして、エンジン本体１の運転にともなつて
発生する騒音は、エンジン補機６からの騒音とと

吸音材１７および制振鋼板１６によつて吸収され
減衰する。したがつて、エンジン本体１およびエ
ンジン補機６と防音カバー１２との間隙から洩れ
る騒音はごく小さい。 Therefore, the noise generated during operation of the engine main body 1, together with the noise from the engine auxiliary equipment 6, collides with the soundproof cover 12 and bounces off, and then collides with the engine main body 1 and the engine auxiliary equipment 6 again and bounces off. The noise collides with the soundproof cover 12,
The sound is absorbed and attenuated by the sound absorbing material 17 and the damping steel plate 16. Therefore, the noise leaking from the gap between the engine body 1, the engine auxiliary machine 6, and the soundproof cover 12 is extremely small.
エンジン本体１のメンテナンスにあたつては、

ジン補機６のメンテナンスも同様である。 When maintaining the engine body 1,
If the soundproof cover 12 is rotated, all sides of the engine body 1 are opened, so there is no problem at all. The same applies to maintenance of the engine auxiliary machine 6.

減衰作用が優れるなどの種々の効果を奏する。 As explained above, according to the present invention, although the soundproof cover is placed on the outside of the engine body and the engine auxiliary equipment in a spaced and opposing position, there is no need to match the shape of the soundproof cover to the complicated shape of the engine body and the engine auxiliary equipment. It is simple and easy to manufacture and install. The lower end of the soundproofing cover is rotatably supported on the lower stay via a hinge, and the upper end of the soundproofing cover is detachably supported on the protruding end of the upper stay. If you disengage the soundproof cover and rotate the soundproof cover around the hinge at the end of the lower stay, free time will be created between the engine body and engine auxiliary equipment and the soundproof cover, making maintenance of the engine body and engine auxiliary equipment easy. It can be done in a short amount of time. In addition, since the soundproof cover is made by pasting a layer of sound absorbing material on the inner surface of a damping steel plate, the sound absorbing material provides a sound absorption effect, and the damping steel plate provides a damping and sound insulation effect, thereby absorbing and attenuating operating noise. It has various effects such as superior action.
