Particle, e.g. soot, filter regeneration device for motor vehicle, has comparator deducing performance difference, from measured parameter and stored particle filter model, being delivered to control unit delivering control setpoint

摘要

The device has sensors measuring a parameter representing engine performance. A module (24a) stores a model (51) of an empty particle filter. A comparator (53) receives the parameter and performance elaborated by the model to deduce a difference of performance (epsilon), representing performance degradation of the engine, which is delivered to a regeneration phase control unit (55) delivering a control setpoint based on the degradation. An independent claim is also included for the regeneration of a particle filter mounted on an exhaust line of an internal combustion engine of a motor vehicle.
