Description

Oxygen sensor for automobiles is the major sensor component in electronic fuel injection engine control system and is the key part to control automobile exhaust emission, reduce automobile pollution to the environment and improve fuel combustion quality of the automotive engine. The 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.

Planar Oxygen Sensor Element Feature:

  • Quick ignition time
  • Good insulation performance
  • Strong resistance to high temperature and poisoning
  • Long lifetime
  • Pump current switch type, conventional switch type, air-fuel ration type, and wide range type are available
