FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: according to proposed method to control operation of internal combustion engine 1, mainly that used to power a vehicle, fuel is injected into combustion chamber 4 at operation of enriched fuel mixture and lean fuel mixture, and changing over between said operating conditions is provided, carrying out changing over from operation of enriched fuel mixture to operation on lean fuel mixture and vice versa. Moreover, accumulation of nitrogen oxides in catalytic converter 12 is done. Then quality function G is determined presenting efficiency of accumulation of nitrogen oxides in catalytic converter 12 depending on time interval DT at a laps of which operation on enriched fuel mixture is interrupted by catalytic converter 12. Quality function G is determined by several successive time intervals DT and, depending on said quality function G, action is made on process of changing over between above-indicated modes of operation.
EFFECT: provision of correct constant control over process of accumulation and release of nitrogen oxides and/or regulation of said process.
