DEVICE AND METHOD OF NOZZLE CONTROLLING OF EXHAUST GAS PROCESSING SYSTEM Russian patent published in 2016 - IPC F01N3/20 F01N3/25 

FIELD: engines.

SUBSTANCE: invention relates to systems of processing of exhaust gases of internal combustion engines. Method of control of nozzle work, which serves for injection of hydrocarbons in the flow of exhaust gases, involves: fuel injection for heating of system units. If the fuel is not injected, then air is supplied for blowing and cooling of the blasting nozzle to prevent deposition of carbon, if the exhaust gas temperature is low. And in essence air supply is stopped to enable passibility of passive heating of blasting nozzle with exhaust gases for oxidation of accumulated carbon, if the temperature of exhaust gases is high enough to provide an oxidation. In the preferred version of the nozzle has a catalytic coating to reduce oxidation temperature of material scale.

EFFECT: using of the invention will prevent coking of nozzle.
