FIELD: engines and pumps.
SUBSTANCE: group of inventions relates to particulate filter cleaning and to system with silencer and particulate filter. Vehicle is equipped with internal-combustion engine and particulate filter arranged in working position inside exhaust system silencer at normal engine operation. Purification process is performed as follows: particulate filter is disconnected and removed from first end of silencer. Further, particulate filter is turned to opposite direction and again installed in cleaning position on said first end of silencer. Then engine is started and its operation is controlled by adjusting frequency of rotation in accordance with given cycle until specified condition is achieved. Engine is stopped and particulate filter is returned into working position inside exhaust system silencer.
EFFECT: group of inventions enables improving methods and systems for particulate filter cleaning in vehicles using available flow of exhaust gases.
