Oxygen sensor chip
Zirconia oxygen sensor chip
Description
Product description
The sensor detects the oxygen level of engine Exhaust emissions and output the corresponding Signal to ECU for reflecting whether the air-fuel Ratio is dense or diluted. ECU will control Fuel-injection and air-input to make it a best air-fuel ratio status, thereby creating an ideal condition for three-way catalyst’s work.
If the gas mixture is too dense, then the fuel must be Reduced, but if it’s too dilute,
then the fuel injection Must be increased. There is only one lambda sensor in a Traditional engine, which is called controlling lambda sensor And it’s installed at the upstream position of three-way Catalyst. there is a diagnosis lambda sensor in newer style Car which is installed at the downstream position of three-Way catalyst to detect whether the controlling lambda sensor is In a best working condition. then the ECU will work out the Compensation dosage of the request of calibration offset.
