Способ по п. 1, дополнительно включающий:мониторинг состояния системы ПООГ;мониторинг температуры отработавших газов; ирегулирование впрыска углеводорода в поток отработавших газов в зависимости от состояния системы ПООГ и температуры отработавших газов.3. Способ по п. 1, включающий подачу потока воздуха через форсунку сразу же после впрыска углеводорода для продувки форсунки с целью удаления остающегося в ней углеводорода.4. Способ по п. 1, в котором подачу потока воздуха через сопло форсунки по существу прекращают, если температура отработавших газов выше порогового уровня, до тех пор пока температура отработавших газов не опустится ниже порогового уровня.5. Способ по п. 1, в котором подачу потока воздуха через сопло форсунки по существу прекращают, когда температура отработавших газов выше порогового уровня, на заданный временной интервал.1. A method for controlling the operation of a nozzle for an exhaust after-treatment system (POG) to prevent carbon deposits, the nozzle of the nozzle having a catalytic coating, and the method includes: selective injection of hydrocarbon fluid into the exhaust stream to increase their temperature; air supply through the nozzle of the nozzle if hydrocarbon is not injected and the temperature of the exhaust gases is below a threshold level; and essentially stopping the passage of air flow through the nozzle of the nozzle if hydrocarbon is not injected and the temperature of the exhaust gases is above a threshold level. 2. The method according to claim 1, further comprising: monitoring the state of the POG system; monitoring the temperature of the exhaust gases; regulation of the injection of hydrocarbon into the exhaust gas stream depending on the state of the POG system and the temperature of the exhaust gas. 3.
