Protecting The Environment - Opel MOVANO Owner's Manual

PROTECTING THE
ENVIRONMENT
The following devices are used for
reducing diesel fuel engine emissions:
oxidising catalytic converter;
exhaust gas recirculation system
(EGR);
particulate filter (DPF) (for
versions/markets, where provided).
73)
DIESEL PARTICULATE
FILTER (DPF)
The Diesel Particulate Filter is a
mechanical filter, integral to the exhaust
system, that physically traps carbon
particles present in the exhaust gases
of diesel engines.
The diesel particulate filter has been
adopted to eliminate almost all
particulates in compliance with current
/ future legal regulations.
During normal use of the vehicle, the
Powertrain Control Module records a
set of data (travel time, type of route,
temperatures reached etc.) and
calculates how much particulate has
been trapped by the filter.
Since this filter physically traps
particulate, it should be regenerated
(cleaned) at regular intervals by burning
carbon particles.
The regeneration procedure is
controlled automatically by the
96
Powertrain Control Module according
to the filter conditions and vehicle
usage conditions.
During regeneration, the following
may occur: a limited increase in the
engine speed, activation of the fan, a
limited increase in fumes and high
temperatures at the exhaust.
These are not faults; they do not impair
vehicle performance or damage the
environment. If the dedicated message
is displayed, refer to the "Warning lights
and messages" section.
IMPORTANT
73) The Diesel particulate filter (DPF)
reaches high temperatures during normal
operation. Do not park the vehicle on
flammable material (grass, dry leaves, pine
needles etc.): fire hazard.
