Abstract: A structure for reducing noise of an engine room includes a hood configured to open and close an engine room, the hood having opposing inside and outside surfaces, wherein the inside surface is inside the engine room when the hood is closed. A weather strip is disposed on the inside surface of the hood, and sealing rails are configured to be tightly pressed against the weather strip to shield noise generated from the engine room.

Abstract: A structure of a soundproof cover for an engine room is mounted on a body frame at a rear side of the engine room in which an engine is mounted. The structure may include two or more piece members that are detachably coupled to each other and collectively form the soundproof cover in a panel shape. The soundproof cover is to be mounted on the body frame so that one side surface of the soundproof cover is directed toward the engine and the other side surface of the soundproof cover is directed toward an interior of a vehicle.

Abstract: A subframe for a vehicle satisfies durability and crash performance of a rear mounting portion during vehicle crash. The subframe may include an upper reinforcement and a lower reinforcement, which are spaced apart from each other and assembled to the subframe, and a rear mounting bracket connected to a chassis via a mounting bolt, wherein the lower reinforcement includes a bolt pushing-inducing trim line connected to a bolt hole and the upper reinforcement includes a pair of deformation-inducing holes formed on both front and rear of a pipe nut such that the mounting bolt is separated from an initial position and the upper reinforcement is deformed when an impact load is applied.

Abstract: A system for treating recirculating nutrients using floating media is disclosed. The system is operated in such way that wastewater influent path is changed between a first mode and a second mode at a certain period of time interval. Wastewater influent at the first mode sequentially flows into a first anoxic tank, a second anoxic tank, and an aerobic tank. Wastewater influent at the second mode sequentially flows into the second anoxic tank, the first anoxic tank, and the aerobic tank. Part of the wastewater that flows into the aerobic tank bypasses the first anoxic tank and the second anoxic tank. Part of the wastewater, which flows from the aerobic tank into the first anoxic tank or from the aerobic tank into the second anoxic tank, continuously bypasses the aerobic tank through an internal recirculation pump.
