FIELD: engines.
SUBSTANCE: invention can be used in internal combustion engine fuel feed control systems. Methods and system for accurate determination of engine cylinder fuel feed errors during automatic restarting of engine (for start-stop operation) are disclosed. Data on fuel feed error can be collected during previous engine restarting specifically in cylinders and specifically on cylinders and specifically on acts of combustion of fuel mixture. Assembled error values of fuel injection can then be used during subsequent engine restarting, specifically to cylinders and specifically to acts of combustion of fuel mixture, in order to improve prediction and compensation of deviations of air-fuel ratio in cranking engine.
EFFECT: technical result is improvement of engine start-up characteristics at its automatic restart.
