FIELD: machine building.
SUBSTANCE: gases in the cylinder move the compressor piston that pumps the atmosphere air via the check valve to the common pneumatic accumulator for all cylinders. During suction cycle in the cylinder the compressor spring moves its piston to the initial position, and atmosphere air via the check valve is pumped in the compressor cavity. To open valve of the internal-combustion engine the control system sets its slide in the position where air from the common pneumatic accumulator enters the valve drive cavity and opens the valve. Closing is performed in the reverse order. For the fuel supply to the combustion chamber the control system sets the slide of air flow control to the position where air from the common pneumatic accumulator enters the cavity of the sprayer plunger drive. The drive of the sprayer piston moves the plunger and ensures injection. The sprayer plunger preparation for next injection is performed in reverse order, as result fuel from the tank via the check valve is supplied to the cavity of the sprayer plunger.
EFFECT: improved efficiency of operation of the internal-combustion engine due to gas distribution adjustment.
