What will the driver notice?
Basically nothing. As long as diesel and AdBlue are topped up in time the driver
doesn’t notice anything regarding the exhaust gas after treatment. The engine
emissions are continually measured, when any malfunction occurs or if you’ve a
low level of AdBlue, this is indicated on the dashboard display as warning.
When excess NO
x
is detected for any reason (for example due to malfunctioning
or if you’re out of AdBlue) the engine’s torque will be restricted to encourage
rectification. Vehicles above 15 tons are reduced in torque by as much as 40%
as soon as it comes to a standstill. If the problem is caused by malfunction of the
vehicle system, the power limit is only activated after 36 driving hours. Largely
sufficient to get home.
As soon as the problem is fixed, full torque capacity is available again.
The anomaly is registered in the vehicle system. This intervention is according to
legislation for all commercial vehicles and regardless of brand or type.
