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 air is fed from the pneumatic accumulator into the drive piston cavity of the intake valve. Gases flowing from the exhaust channel of exhausted combustion products into the cavities between the exhaust valve, the intake valve and in the air or fuel mixture intake channel create decrease in air or fuel mixture pressure less than atmospheric. Air or fuel mixture begins to move toward the exhaust channel of exhaust combustion products. The cylinder filling occurs on the suction stroke. At that the system sets the intake valve into open position and the exhaust valve into closed position. 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.
