Oxygen Sensors

Oxygen sensors detect the presence of oxygen on the extractor collector and allow the ECU to redesign the synchronization of the injection and the fuel proportion. The sensible element is made of Zirconium dioxide, silvered platinum. These two materials work as battery electrodes: Meanwhile the external surface is in contact with exhaust gases, the internal surface detects the atmosphere oxygen. The voltage generated by the different oxygen concentration on the two surfaces is sent to ECU that adjust the fuel mixture by the injection system.
