ADAPTATION METHOD OF TEMPERATURE CONTROL OF PARTICLE FILTER-CATCHER Russian patent published in 2013 - IPC F01N3/25 F01N9/00 

FIELD: machine building.

SUBSTANCE: temperature control method of a particle filter-catcher of exhaust system (1) during a regeneration phase of the same filter by fuel spray into exhaust gases, which involves the stages, at which temperature (T5) is measured at the level of particle filter-catcher; amount of fuel (Q_igec) is determined, which is required for spray into exhaust gases; besides, the above amount includes the first constituent (Qc1c) determined by means of an open circuit of automatic control, which does not take account of the measured temperature, and the same amount contains the second constituent (Qc2) determined by means of a closed circuit of automatic control, which takes account of the measured temperature; and depending on amplitude of the second constituent relative to the determined amount of fuel, correction (Kc) is determined for the first constituent, and the same correction is introduced to the open circuit of automatic control.

EFFECT: providing quick and effective filter regeneration.
