FIELD: engines and pumps.
SUBSTANCE: device for cleaning of spent gases of internal combustion engine from nitrogen oxides comprises chamber of low temperature plasma with corona electrode and two insulators, inlet and outlet nozzles and high voltage source, additional chamber with catalyst and two coaxially installed electrodes with holes for gas entry and exit, at that internal electrode is electrically connected to corona electrode, and peripheral electrode is located with gap relative to body of additional chamber and is electrically connected to its body.
EFFECT: increased efficiency of spent gases cleaning from nitrogen oxides.
