Abstract
A sound-absorbing moisture-absorbing noise-reducing automobile engine timing cover is used for solving the problems that noise and moist gas in the engine has adverse effects on parts and the like. The timing cover is in a split-combined structure, and is composed of an upper cover, and a lower cover and a middle cover, wherein the upper cover and the lower cover are in layer structures, each layer structure is integrally formed by stamping an inner layer, and an outer layer and a middle layer. The inner layers and the outer layers are made of carbon fabric materials, and the middle layers are mixed material layers made of butyl rubber and water-absorbing polymer absorbents. The timing cover has the advantages that firstly by means of the split-combined structure, the timing cover is convenient to disassemble and assemble and assembly efficiency is improved; secondly the upper cover and the lower cover adopt the layer structures, so moisture released from a gas vent of a water pump cover in the engine cover is effectively absorbed and service life of the engine is improved; and thirdly grooves arranged in the outer surface of the timing cover serve as reinforcement ribs, machining and manufacture are convenient, manufacturability is improved, and strength and modal of the timing cover are improved.
