This oxygen sensor for Acdelco adopts three-way catalyst, thus to obtain a high exhaust gas purification rate and reduce the components of carbon monoxide, and nitrogen oxides in the exhaust gas. Due to the high performance of three-way catalyst, the air-fuel ratio is accurately controlled so that it is always close to the standard air-fuel ratio.
This oxygen sensor for Acdelco can be an essential element on engines with three-way catalytic converters to reduce exhaust pollution. As the air-fuel ratio of the mixture deviates from the theoretical air-fuel ratio, the purification capacity of the three-way catalyst for CO, HC and NOx will improved perfecxtly. Due to the high performance, our oxygen sensor for Acdelco can be installed in the exhaust pipe to detect the oxygen concentration in the exhaust and The ECU sends a feedback signal, and then the ECU controls the increase or decrease of the fuel injection quantity. Due to the high performance, it ensures longer service life for use.
