FIELD: engines and pumps.SUBSTANCE: control system connects a shaft of non-reversing starter mechanism to a crank shaft of an internal combustion engine (ICE) and rotates it. If the direction of rotation of the starter mechanism shaft doesn't coincide with the pre-set direction of the crankshaft rotation, the control system at position of the piston near the top dead point at the moment, when above the piston the pressure of gases is increased to the value providing the fuel combustion conditions, disconnects shafts and sets a liquid flow control spool of the nozzle drive piston into the position at which liquid from the hydraulic accumulator flows into the top cavity of the nozzle plunger drive piston, and the nozzle injects fuel into the combustion chamber. Fuel is burnt, and combustion products change the direction of the piston movement and the crankshaft rotation to the opposite. At the position of the piston near the lower dead point the control system sets the liquid flow control spool into the position at which liquid from the hydraulic accumulator flows into the top cavity of the drive piston of the gas-distributing valve. The exhaust gas-distributing valve connected to it opens. After discharge of gases in atmosphere the kinetic energy of the flywheel and the crankshaft rotates it, and the control system ensures functioning of gas-distributing valves and the fuel nozzle according to the pre-set direction of rotation of the ICE crankshaft.EFFECT: higher efficiency of engine control.3 dwg |
