FIELD: engines and pumps.
SUBSTANCE: gases in the cylinder of the internal combustion engine (ICE) press on a pump piston end face, and liquid enters the hydraulic accumulator, after that the spring returns it in a starting position and through the check valve liquid from the compensation tank is forced out there. For opening of the ICE valve the control system sets a valve spool in the position at which liquid from the hydraulic accumulator goes to the top cavity of the drive piston of the gas-distributing valve and the gas-distributing valve opens. The exhausted liquid from the lower cavity is forced out into the compensation tank. For closing of the gas-distributing valve the control system follows the inverse sequence. For fuel supply the control system sets the nozzle spool into the position at which liquid of the accumulator goes into the top cavity of the drive piston of the nozzle plunger, and the nozzle plunger injects fuel into the combustion chamber. And at the return movement the nozzle plunger sucks fuel from the fuel tank.
EFFECT: improvement of efficiency of internal combustion engine due to regulation of its gas distribution valves and nozzles by the common hydraulic system.
