EXHAUST SYSTEM COMPONENT INCLUDING A SELF-HEALING CERAMIC MATERIAL AND INTERNAL COMBUSTION ENGINE EQUIPPED WITH THE COMPONENT

WIPO Patent Application WO/2015/033526

A3

An object of the present invention is to provide an exhaust system component having excellent properties to be located in an exhaust flow path from an internal combustion engine, particularly, an exhaust system component having an extended use-life. The exhaust system component of the present invention for an internal combustion engine has a self-healing ceramic material and an electric heater for heating the self-healing ceramic material. In particular, the exhaust system component of the present invention is an oxygen sensor (110) having a detection element (111) and an electric heater (112), wherein the detection element (111) has a solid electrolyte layer, a reference-side electrode layer, an exhaust-side electrode layer, and a diffusion layer and/or a trap layer each composed of a self-healing ceramic material. The exhaust system component can be as well an exhaust purification system such as a straight flowpath exhaust purifier include a catalytic honeycomb substrate (601) including the self-healing ceramic material.
