The chemistry behind the Volkswagen emissions scandal
Explore the chemical processes used in diesel engines and the controversy surrounding Volkswagen's attempts to manipulate nitrogen oxide emissions. This video examines the science of urea-based technologies and the complexities of engine regulation.
The video explores the chemistry involved in the recent controversy surrounding Volkswagen cars. While many diesel engines utilize urea—marketed under the name AdBlue—to manage emissions, the Professor clarifies the technical nuances of the scandal. He notes that while urea is a common method for NOx reduction, the specific technique used by Volkswagen to manipulate computer software involved a different technology for removing nitrogen oxides.
