ZrO2 oxygen sensor
Bosch (Germany) and NTK (Japan) are largest manufacturers of socalled lambda sensors.
TWC
Cars are equipped with a three-way catalytic converter, so-called as it helps decrease carbon monoxide, hydrocarbon and NOx emissions using both reduction and oxidation catalysts (such as platinum, rhodium and/or palladium).
Doped Zirconia Electrolyte
Why dope?
The yttria dopant introduces a defect into the zirconia crystal that leaves voids. In the solid zirconia, some Zr4+ ions are replaced by Y3+ ions so that oxygen vacancies are created which allow the oxide anion, O2-, to move in the solid, giving a solid electrolyte.

Sensors (detectors/transducers) covers a wide category of devices used to monitor, measure, test, analyse data as generated due to changes in a measured norm (usually concentration for chemical sensors).
In order to reduce emissions, modern car engines carefully control the amount of fuel they burn. They try to keep the air-tofuel ratio very close to the stoichiometric point, which is the calculated ideal ratio of air to fuel, using a lambda sensor feedback. Theoretically, at this ratio, all of the fuel will be burned using all of the oxygen in the air. Fo:1. As engine and driving conditions change, this ratio changes as well. Sometimes it will run richer or leaner than the ideal 14.7:1.
