FIELD: engine building.
SUBSTANCE: method for simultaneously driving multiple fuel injection nozzles of an internal combustion engine by a liquid reciprocating electric drive, differing in the fact that when an alternating voltage is applied to the coil of the reciprocating electric drive, the magnet plunger performs oscillatory movements so that the liquid from both cavities of the magnet plunger enters the power hydraulic accumulator through one pair of check valves, and through the other pair of check valves, the liquid from the compensating hydraulic accumulator enters the opposite cavities of the magnet plunger. The control system sets the gates of the two-seat valve to the position wherein the liquid from the power hydraulic accumulator enters, through the gate channel of the two-seat valve, the cavity of the drive piston of the fuel injection nozzles at the entry whereto the fuel injection nozzles inject fuel into the combustion chamber of the internal combustion engine. The liquid from the opposite cavity of the drive piston of the fuel injection nozzles enters the compensation hydraulic accumulator via the gate channel of the two-seat valve. In order to return the fuel injection nozzles to the initial state, the control system sets the gates of the two-seat valve to the position wherein the liquid from the power hydraulic accumulator enters, through the gate channel of the two-seat valve, the cavity of the drive piston of the fuel injection nozzles at the entry whereto the fuel injection nozzle returns to the initial state. The liquid from the opposite cavity of the drive piston of the fuel injection nozzles enters the compensation hydraulic accumulator via the gate channel of the two-seat valve.
EFFECT: simultaneous driving of multiple fuel injection nozzles in an internal combustion engine.
