Oxygen sensor (incision): The outer part B of the sensor is in contact with the outside air, while the inner part A is in contact with the exhaust gas flow. Due to the different oxygen content, an electrical voltage of different magnitudes arises. The measured values are fed to the control device, which changes the amount of injected fuel accordingly. 1 - ceramic support tube, 2 - protective cover, 3 - sensor housing, 4 - electrical resistance.
