Self Study Program 446 – The 2.5L TDI EURO V engines with SCR system in Crafter PDF free online

The worldwide tightening of emission limits for passenger cars and commercial vehicles with diesel engines calls for both the continuous improvement of combustion inside the actual engine and increasingly powerful exhaust gas treatment systems.

The new 2.5l TDI engines in the Crafter are equipped with the SCR (Selective Catalytic Reduction) system. Volkswagen Commercial Vehicles is thus making a further contribution to protecting the environment and combating climate change.

In this self-study programme, you can find out about an exhaust gas treatment system that reduces harmful nitrogen oxides (NOx) in the exhaust gas.

This self-study programme describes the Selective Catalytic Reduction SCR) exhaust
gas treatment system for the Crafter. Further information about the SCR system can be found in self-study programme 424 “The Selective Catalytic Reduction exhaust gas treatment system”.
