Pollution control device

Claim 1

An antipollution device for substantially reducing the carbon monoxide and hydrocarbons produced by the exhaust from a vehicle having a combustion engine and an exhaust pipe, comprising: a container having an inlet and an outlet at opposite ends thereof, said inlet adapted to be connected to the engine manifold of a combustion engine and said outlet adapted to be connected to the exhaust pipe so that exhaust gases flow in a substantially longitudinal direction between said inlet and said outlet; the walls of said container being lined with a castable refractory material containing a binder resistant to high temperature, silica, and fire clay; said container further including a stacked array of members formed of said castable refractory material; said stacked array including layers of members wherein alternate layers are longitudinally and transversely arranged in said container to form a grid having passageways between said lined walls and said members; said passageways extending between said inlet and said outlet so that the exhaust gases from said engine pass through said passageways and operate to substantially reduce the carbon monoxide and hydrocarbons contained in the exhaust gases.
