FIELD: engines and pumps.
SUBSTANCE: in the final release phase the control slide valve system opens an intake valve of three-valve gas distributor. To this end, the liquid is fed from the hydraulic accumulator into the drive piston cavity of the exhaust valve. Exhaust gases flowing from the exhaust channel into the cavities between the exhaust valve, the intake valve and in the air or fuel mixture intake channel create a vacuum. Air or fuel mixture begins to move toward the exhaust channel. The cylinder filling occurs on the suction stroke. The system closes the exhaust valve. The valve timing overlapping and kinetic energy of the air flow or fuel mixture additionally fills the ICE air cylinder with air or fuel mixture.
EFFECT: increase of cylinder filling.
