The invention relates to an improvement to exhaust gas recirculation (EGR) systems and in particular to a high temperature resistant wire screen affixed to the inlet opening of a carbon gasket for sealing the EGR valve to the manifold of an automobile engine and providing an effective barrier to keep large exhaust carbon flakes from entering the EGR system and clogging the valve.
In an exhaust gas recirculation system adapted to extract exhaust gas from an automobile engine manifold and reintroduce said exhaust gas into the combustion cycle of an automobile engine to lower combustion temperature and thus reduce formation of nitrous oxides, the improvement comprising: a high temperature resistant gasket having an inlet opening and adapted to provide a seal between said exhaust gas recirculation system and said manifold of said automobile engine; and a high temperature resistant filter affixed to said gasket within said inlet openi...
