DPF
The Diesel Particle Filter (DPF) function manages DPF regeneration,
DPF component replacement teach-in, and DPF teach-in after
replacing the engine control unit.
The ECM monitors driving style and selects a suitable time to employ
regeneration. Cars driven a lot at idling speed and low load will
attempt to regenerate earlier than cars driven more with higher load
and speed. For regeneration to take place, a prolonged high exhaust
temperature must be obtained.
In the event of the car being driven in such a way that regeneration is
not possible, i.e., frequent short journeys, a diagnostic trouble code
will eventually be registered in addition to the DPF light and “Check
Engine” indicators displaying. A service regeneration can be
requested in the workshop using the diagnostic tool.
DPF regeneration is used to clear PM (Particulate Matter) from the
DPF filter through continuous combustion oxidation mode (such as
high-temperature heating combustion, fuel additive or catalyst reduce
PM ignition combustion) to stabilize the filter performance.
DPF regeneration may be performed in the following cases:
The exhaust back pressure sensor is replaced.
The PM trap is removed or replaced.
The fuel additive nozzle is removed or replaced.
The catalytic oxidizer is removed or replaced.
