FIELD: transport.
SUBSTANCE: invention relates to operation of diesel particle filters. Method of control over particle filter (15) of diesel (11) with carbon-black pickup (18) arranged at diesel particle filter (15) outlet (19). Note here that said carbon-black pickup (18) operates in compliance with the sequence of carbon-black filling phases divided by regeneration phases. This process comprises the stage whereat filter (15) boundary efficiency (Ebdl) is set. During regeneration phase readings of the counter that displays the level of pickup (18) filling with carbon-black are reset. Counter readings (I) are iteratively increased during the next filter filling stage unless readings (I) reach the counter preset threshold readings (lth). Filter (15) efficiency DPF is considered inadmissible in case the next regeneration phase of pickup (18) starts when counter readings (I) are lower than said preset threshold magnitudes (Ith).
EFFECT: reliable evaluation of diesel particle filter under real road conditions.
