FIELD: engines and pumps.
SUBSTANCE: invention relates to the timing of internal combustion engines (ICE). Invention consists in the fact that the control system converts the voltage of the electricity to alternating pulses of electricity which are fed to the package of piezoceramic elements in the piezopump leading piston making oscillations and pumping hydraulic fluid. Fluid flows through the check valve in the accumulator system, and into the cavity of the piston piezopump fluid flows through the check valve of the compensating accumulator. To open the engine valve the timing control system puts a fluid flow control valve to a position in which it is supplied from the accumulator into a corresponding cavity of the piston valve timing and connected thereto a gas distribution valve opens. To close the valve timing control system operates in reverse order.
EFFECT: technical result is to increase the efficiency of the system.
