Efficient and Clean: Exhaust Aftertreatment for Gasoline and Diesel Engines

  • Total exhaust aftertreatment system reduces nitrogen oxide emissions of TDI engines by more than 90 percent
  • Audi in charge of systems for new V6 TDI engine generation within the VW Group
  • Gasoline particulate filter completes exhaust gas purification of SI engines

Audi is using complex exhaust aftertreatment systems to meet increasingly lower emission limits. Besides the utilization of in-engine technology, the latest gasoline and diesel engines meet the strict standards especially due to powerful and sophisticated exhaust gas purification systems. Particulate filters complement catalytic exhaust aftertreatment on both TDI and TFSI engines.

What are the current challenges of exhaust gas purification?
