Introductions:
In engines that use a three-way catalytic converter to reduce exhaust pollution, the oxygen sensor is an indispensable component. Once the air-fuel ratio of the mixture deviates from the theoretical air-fuel ratio, the purification 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 The ECU sends out a feedback signal, and then the ECU controls the increase or decrease of the fuel injection volume of the injector, so as to control the air-fuel ratio of the mixture near the theoretical value.
