Exhaust system with exhaust emission control

To comply with the exhaust emission regulations, the truck crane may only
be run with the exhaust system with SCR catalytic converter (SCR =
Selective Catalytic Reduction).
The exhaust gas is treated using a DEF system. To do this, AdBlue (DEF)
(Diesel Exhaust Fluid) from the DEF tank is injected into the exhaust system.
The motor output is automatically sharply reduced when there is not
enough AdBlue solution available. Driving with an empty AdBlue tank will
invalidate the truck crane's licence for use on public roads;
