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

摘要

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 having a detection element and an electric heater, wherein the detection element 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.

主权项

1. A method for controlling an internal combustion engine having an exhaust system component and a combustion chamber,
wherein the exhaust system component comprises a self-healing ceramic material, and an electric heater for heating the self-healing ceramic material and wherein the method comprises heating the self-healing ceramic material by the electric heater when combustion is not performed in the combustion chamber.
