TURBO SCREEN

摘要

The present invention generally relates to methods and apparatus for use in exhaust manifold assemblies of large diesel engines. In one aspect, a screen for use in an exhaust manifold assembly is provided. The screen includes a plate formed in a concave shape. The plate has a concave surface. The concave surface has a plurality of apertures and a plurality of non-intersecting, radially oriented slots formed therein. The plurality of slots and apertures have a size and open area selected to prevent debris from entering a turbo charger. The slots separate the apertures into predefined sections, and a radially outward end of the slots is spaced from a perimeter of the plate. In another aspect, a reducer assembly for use in an exhaust manifold assembly is provided. In yet a further aspect, a method of using a screen in an exhaust manifold assembly is provided.
