Oxygen sensor protective coating
The vehicle oxygen sensor is a key feedback sensor in the electronic fuel injection engine control system. It is a key part to control vehicle exhaust emissions, reduce vehicle pollution to the environment, and improve the quality of vehicle engine fuel combustion.
The research and development of relevant properties and durable protective coatings for vehicle oxygen sensors and nitrogen and oxygen sensors have broken the monopoly of foreign enterprises (such as BOSCH,NTK,DENSO,DELPHI), and realized the preparation of relevant ceramic coatings on the surface of the precious metal catalytic layer on the surface of the oxygen sensor core, thus greatly improving the catalytic capacity and service life of precious metals and promoting the localization process of sensors.
