  1. Product Introduction

Automotive oxygen sensor is the major sensor component in electronic fuel injection engine control system, and is the key part to control automotive exhaust emission, reduce automotive pollution and improve fuel combustion quality. Oxygen sensor is used in the feedback control system of the electronic control fuel injection device, to detect the concentration of oxygen in the exhaust gas and the air fuel ratio. It is also used to monitor theoretical air fuel ratio (14.7:1) combustion in the engine, and to provide feedback signals to the computer.
