Oxygen sensor emissions control EU6 DDE7
WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.
In order to comply with the more stringent exhaust-emission regulations of the EURO6 (EU6) standard, exhaust emissions control is implemented on vehicles with EURO6 by two oxygen sensors. The oxygen sensors are located in front of the oxidation catalytic converter and after the oxidation catalytic converter.
To reduce nitrogen oxide emissions further, an oxidation catalytic converter with a modified coating is used.
