The invention discloses an engine trim cover. The engine trim cover comprises a skin and a polyurethane foaming raw material, wherein firstly, the skin is heated, softened and arranged on the surfaceof a mold by plastic uptake; then, the mold is closed, and the polyurethane foaming raw material is injected into the mold through foaming equipment; the polyurethane foaming raw material reacts withthe skin for molding after being injected into the mold; and a product is extracted after reaction molding and is placed on a shaping tool for cooling shaping. According to the engine trim cover, theselected skin is used as the appearance surface of the product, a traditional engine cover surface treatment process is replaced, and the environmental protection requirement is improved; and meanwhile, a polyurethane foaming formula is simplified, the product is lightweight, finally the cost of parts is reduced, and benefits are created for automobile cost and light weight. 本发明公开了一种发动机装饰罩，包括表皮、聚氨酯发泡原料，先将表皮经过加温后软化吸塑至模具表面；然后
