Method for monitoring a particle filter |
摘要 |
A particle filter is monitored with a sequence of steps. A pressure loss at the particle filter is measured. The volumetric flow of exhaust gas is acquired and a filter load value is calculated from the pressure loss and the volumetric flow of exhaust gas. The filter load value is recorded as a function of a drive parameter and the filter load value is differentiated with respect to the drive parameter. The differentiation of the filter load allows a particle filter breakdown to be deduced when the differentiation is less than or equal to zero.
