FIELD: machine building.
SUBSTANCE: procedure for desulphitation of neutraliser (6) NOx Trap in system of exhaust of discharge gases of diesel engine is designed for removal of at least part of sulphur retained with neutraliser NOx Trap during operation of engine and consists in following stages: depletion of product of reforming from motor fuel with reforming-apparatus, heating neutraliser NOx Trap for period of time till there is achieved specified temperature of desulphitation in neutraliser NOx Trap, withdrawal of flow of discharge gases form point (2) of branch of exhaust system located before point of injection and carrying on injection of reforming product into neutraliser NOx Trap desulphitation. Also, implementation of the above said stages of the procedure does not influence enrichment of mixture of a diesel engine. The invention also refers to the procedure for regeneration of system of discharge gases exhaust, to the system of discharge gases exhaust in diesel engines and to the procedure of regeneration of a filter-trap of particles.
EFFECT: desulphitation not effecting mode of engine operation and minimised over-consumption of fuel.
