Abstract
A method for detecting the number of particles in the exhaust gas of combustion engines, wherein a value that is characteristic for the quantity of the particles is determined, for example, in form of the blackening of a filter or determination of the concentration, wherein, furthermore, the suction time and/or the suction volume of the exhaust gas are measured, and wherein, if necessary, the blackening rate is calculated, based on the characteristic value and the suction time and/or the suction volume by way of a first conversion function, wherein the number of particles is determined based on the characteristic value, the suction time and/or the suction volume as well as the data of the first conversion function by way of a second conversion function.
