Diesel and Urea (2015x26)

Data di messa in onda: Set 26, 2015

The Professor discusses some of the chemistry behind the recent controversy involving Volkswagen cars. CLARIFICATION: While many diesel engines (including VW cars) use urea as discussed (marketed as AdBlue), we've heard from viewers explaining the technique VW "fiddled with the computer" used another NOX-removal technology.
