FIELD: engine building.
SUBSTANCE: invention can be used in the internal combustion engines. Method for engine operation consists in evaluating multiple values of engine fuel consumption for operation of engine with multiple configurations, providing different actual total number of connected cylinders. Engine is actuated with actual total number of connected cylinders based on said plurality of engine fuel consumption values. Invention discloses version of method for engine operation and vehicle system.
EFFECT: technical result consists in prevention of operation parameters of cylinders remaining connected to border range, in which ignition advance angle is limited in connection with possibility of detonation and in which engine fuel economy decreases.
