INTERNAL COMBUSTION ENGINE WITH DOUBLE SYSTEM OF FUEL INJECTION Russian patent published in 2009 - IPC F02M63/00 F02P5/15 

FIELD: engines and pumps.

SUBSTANCE: engine comprises the following components: nozzle for direct injection; nozzle for injection of fuel into inlet channels; unit for determination of engine operation mode intended for detection of engine operation mode; unit for control of injected fuel amount intended for tracking of engine operation mode and control of according amount of fuel injected from nozzle for direct injection and nozzle for fuel injection into inlet channels, depending on mode of engine operation; memory unit with inbuilt four tables of ignition dwell angle cards, including the first card of ignition dwell angle. The first card of ignition dwell angle is made based on engine operation mode so that ignition dwell angle during fuel injection with application of only nozzle for direct injection actually corresponds to moment for creation of maximum torque. The second card of ignition dwell card is made based on engine operation mode so that ignition dwell angle during fuel injection with application of only nozzle for direct injection actually corresponds to moment of torque creation at the border of detonation. The third card of ignition dwell angle is made based on engine operation mode so that ignition dwell angle during injection of fuel with application of only nozzle for fuel injection into inlet channels actually corresponds to moment of maximum torque creation. The fourth card of ignition dwell angle is made based on mode of engine operation so that ignition dwell angle during fuel injection with application of only nozzle for fuel injection into inlet channels actually corresponds to moment for creation of torque at the border of detonation. Unit for control of ignition dwell angle is intended for control of cylinder ignition moment, using ratio of fuel amount injected by nozzle for direct injection and nozzle for fuel injection into inlet channels, and four tables of ignition dwell angle cards.

EFFECT: invention makes it possible to prevent detonation in internal combustion engine by simple method.
