Pollution control unit e.g. particle filter, regeneration system for motor vehicle diesel engine, has soot quantity prediction units with units that compare soot quantities determined by soot sensor to correct operation of prediction units

摘要

The system has control units (5) to control the operation of a diesel engine (3) of a motor vehicle, where the units have prediction units (6, 7) to predict the quantity of soot trapped in pollution control units (1) according to the operating conditions of the engine. A soot sensor (8) is placed in the upstream of the units (1) in an exhaust line of the engine. The units (6, 7) have comparison units that compare the quantities determined by the sensor to correct the operation of the units (6, 7).
