Oxygen sensor ceramic is the core functional component of automotive lambda sensors, mainly made of high-purity zirconia ceramic material. It features stable oxygen ion conductivity, excellent high-temperature resistance, and strong thermal shock resistance.
This ceramic element works under extreme exhaust temperature conditions to accurately sense oxygen concentration in engine exhaust gas. It converts oxygen difference signals into electrical signals, helping the vehicle ECU adjust the air-fuel ratio in real time, improve combustion efficiency, reduce fuel consumption, and lower exhaust emissions.
