INJECTION FUEL CONTROL DEVICE AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE Russian patent published in 2018 - IPC F02D41/12 F02D41/34 F02D15/02 

FIELD: motors and pumps.

SUBSTANCE: invention relates to controlling fuel injection when an internal combustion engine is slowed down. Internal combustion engine is proposed comprising: an injection injector into an induction port for injecting fuel into the induction port and a direct injection injector for injecting fuel into a combustion chamber. Controller instructs the injection injector into the induction port and the direct injection injector to inject fuel based on the operating mode of the internal combustion engine. Additionally, the controller increases the injection volume of the direct injection injector above the normal injection volume of the direct injection injector, when the internal combustion engine slows down, thereby rapidly reducing the fuel pressure of the direct injection injector.

EFFECT: technical result consists in reducing the fuel pressure of the direct injection injector in the hindrance state.
