초록

A manifold for internal combustion engines is provided which has a unique insulation system for maintaining a skin temperature of the manifold below 400°F. The manifold includes an exhaust conduit made up of axially spaced and aligned segments with provision for preventing excessive leakage of exhaust gases between the spaced segments. Each segment has an exhaust port extending at an angle thereto. Two or more members of corrugated or crumpled thin foil are concentrically arranged about the ports and about the conduit with air gaps between the conduit an...

청구항

In an exhaust manifold spanning at least two ports of an engine comprising: (a) an inner conduit of thin steel, (b) at least two concentrically arranged tubular members of highly reflective material encircling said conduit and being spaced from each other and from said conduit, and (c) a casing surrounding the tubular members and conduit and having the ends of said members embedded therein, whereby the reflective surfaces of the members reflect the heat into the conduit so that only limited amounts of heat penetrates to the outer surface of the manifold.
