ICE FIRING POINT CONTROL DEVICE Russian patent published in 2015 - IPC F02P5/15 

FIELD: engines and pumps.

SUBSTANCE: proposed device comprises the modules that follow: injection point determination module; engine rpm determination module; engine load determination module and module for storage of control data on variation of optimum firing point relative to engine rpm and engine load as well as control on correction factor. These indices are related with optimum firing point relative to engine load at specific fuel injection moment. At call to control data, optimum firing point variation is defined by specific fuel injection moment and definite engine rpm. Here, departure between appropriate variations of optimum injection point is determined. At call to control data of correction factor, the latter is defined relative to definite engine load at specific fuel injection moment. Corrected optimum firing point variation is defined from correction factor and departure of optimum firing point.

EFFECT: reduced associate computation load at preparation of control map.
