METHOD FOR OPERATING SPARK-IGNITION ENGINE WITH EXHAUST AFTERTREATMENT AND INTERNAL COMBUSTION ENGINE Russian patent published in 2016 - IPC F01N9/00 B01D53/00 

FIELD: engines.

SUBSTANCE: group of inventions relates to method of internal combustion engine with spark ignition operation. Method has one cylinder and one exhaust pipeline for discharge of exhaust gases from one cylinder. Particulate filter for collection and combustion of soot particles in exhaust gases, installed in one exhaust pipe, in which to initiate process of regeneration of particulate filter temperature is increased filter to value greater than previously specified minimum filter recovery temperature by increasing exhaust gas temperature due to installation of ignition moment in mode of delayed ignition or by one late fuel injection in one cylinder and engine operation at hyperstoichiometric mode at λ > 1.

EFFECT: technical result is development of method of engine with spark ignition, equipped with particulate filter, may operate, thus providing conditions of frequent filter regeneration.
