Description
Oxygen Sensor
What is Oxygen Sensor?
Oxygen sensors are essential components on engines that use three-way catalytic converters to reduce exhaust pollution. Once the air-fuel ratio of the mixture deviates from the theoretical air-fuel ratio, the cleaning ability of the three-way catalyst for CO, HC and NOx will drop sharply. Therefore, an oxygen sensor is installed in the exhaust pipe to detect the concentration of oxygen in the exhaust gas and send a feedback signal to the ECU, which then controls the increase or decrease of the injector injection volume, so as to control the air-fuel ratio of the mixture near the theoretical value.
