Exhaust system with exhaust emission control

In order to adhere to the exhaust emission regulations, you are only permit-
ted to drive the crane with the multi-stage exhaust system consisting of
DOC catalytic converter, DPF particle filter, SCR catalytic converter (DOC =
Diesel Oxidation Catalyst, DPF = Diesel Particulate Filter, SCR = Selective
Catalytic Reduction).
The exhaust gas is cleaned with an AdBlue system (DEF). AdBlue (DEF)
(Diesel Exhaust Fluid) from the from the DEF tank is injected into the mixing
tube in the exhaust system for this.
The motor output is automatically sharply reduced when there is not
enough AdBlue solution available. Driving with an empty AdBlue tank will
cause the engine to malfunction;
