Sell Oxygen Sensor

Description

The oxygen sensor is an essential component of the engine using the catalytic converter in order to reduce exhaust pollution. Once the air-fuel ratio of the gas mixture is deviation from the theoretical air fuel ratio, the purifying capacity of catalyst for CO, HC and NOx will drop sharply. Oxygen sensor is installed in the exhaust pipe, in order to detect the oxygen concentration of exhaust gas. It will send the feedback signal to the ECU, ECU will control the amount of the increase or decrease of the fuel injection from fuel injector.
