The Audi Q7 3.0 TDI quattro is featuring the cleanest diesel in the world and after watching these two great videos you know why. Vorsprung durch Technik is all we say!
Unfortunately the source website is using some nasty autoplay on videos that’s why we haven’t included them here, head over to the site to watch them!
Audi’s Günter Schiele elaborates on the 3.0 TDI’s downstream exhaust emission control system, which reduces emissions by up to 90 percent. The system uses AdBlue, a biologically degradable, waterborne additive that is injected in small amounts upstream of the DeNOx catalytic converter. In addition to the catalytic converter, the exhaust emission control system comprises the metering module, the AdBlue tank and heated lines, as well as an extensive system of sensors. The additional oxidizing catalytic converter and the highly efficient, regulated diesel particulate filter round off the comprehensive emission control system.
