Method for verifying an initial value determined using at least one measurement, method for treating a diesel particulate filter and device for verifying a differential pressure value

摘要

The method involves comparing a difference between a difference pressure value (deltap) and a correction value (deltapoffset) with a tolerance threshold value, and detecting the difference pressure value as false when the difference is larger than the threshold value. The correction value corresponds to two difference pressure base values at a diesel particle filter in an exhaust gas section of a diesel assembly when exhaust gas does not flow through the filter, where one of the base values is a value determined by measurement at the filter. Independent claims are also included for the following: (1) a method for treating i.e. cleaning, a diesel particle filter (2) a device for verifying a difference pressure value in a diesel particle filter (3) a device for treating i.e. cleaning, a diesel particle filter (4) a computer program for executing a method for verifying a difference pressure value in a diesel particle filter.
