7.5 Exhaust system with exhaust emission control
Overview To comply with the exhaust emission regulations, the truck crane may
only be run with the
exhaust system with SCR catalytic converter
( SCR = S elective C atalytic R eduction).
The exhaust gas is cleaned with an AdBlue system (DEF). To do this, AdBlue
(DEF) ( D iesel E xhaust F luid) from the AdBlue 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;
