ABSTRACT:
A method for the controlled addition of an additive to the fuel supply of a vehicle internal combustion engine, in particular a diesel engine with an exhaust particulate filter, in which the addition is performed as a function of an increase in the fuel supply. While the vehicle is in motion with the engine running, the fuel level is measured at predetermined short time intervals and, having been averaged over a predetermined number of these time intervals, is fed to a measured-value storage device in which the previous average value is compared with the new average value. When a differential value is detected in the average value comparison which exceeds a predetermined tolerance level, an addition of additive proportional to the increase in the level is triggered. After each comparison, the previous average value is erased and replaced by the new average value.
