FIELD: machine building.
SUBSTANCE: present invention relates to systems and methods of internal combustion engine operation control, which comprises injectors of high pressure of fuel injection into inlet channels and direct injection. Said pressure pulsations occur as a result of pressure pulsations created by fuel high-pressure pump feeding fuel both into injection fuel stage and into direct injection fuel stage. Middle of the fuel injection pulse into the inlet channels is located at the intersection of the average pressure and pressure pulsations in order to compensate for the effects of pulsations leading to pressure higher and lower than the average value.
EFFECT: technical result consists in reduction of fuel supply errors, arising from pressure pulsations in fuel injection rail into inlet channels.
