CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE Russian patent published in 2019 - IPC F02D41/14 F01N9/00 F02P5/15 

FIELD: engines and pumps.

SUBSTANCE: invention relates to a control device for an internal combustion engine, comprising a catalyst with the ability to process exhaust gas from multiple cylinders and fuel injection valves. Proposed control device for an internal combustion engine, comprising: an electronic control module with the ability to process mixing control to control the fuel injection valve based on the requested injection volume in such a way that part of the cylinders of the plurality of cylinders become depleted mixture combustion cylinders, and cylinders different from the cylinder part of the number of cylinders become combustion cylinders of the rich mixture, and limiting processing, if the requested injection volume is equal to or higher than the first injection volume, for refusing to set a limit on the handling of the mix control, and if the requested injection volume is within the range of the second injection volume for the injection volume smaller than the first injection volume, to limit the handling of the mixing control by the side on which the degree of depletion of the air-fuel ratio of the cylinder, which has the most lean air-fuel ratio between the cylinders, is reduced.

EFFECT: technical result is to improve the accuracy of controlling the amount of fuel injection.
