FIELD: engines and pumps.
SUBSTANCE: pneumatic drive of fuel atomiser of fire piston engine includes control system of fuel atomiser drive, atomiser drive piston, fuel distributing valves. Drive is equipped with hydraulic accumulator, plunger connected to atomiser drive piston, channel of air supply to gas distributor and the channel interconnected to atmosphere. In order to provide action of pneumatic drive of fuel atomiszer, air is exhausted on movement route of air from compressor to combustion chamber of free piston engine. For that purpose, on air movement route from compressor, some portion of air via air supply channel to gas distributor enters through the latter the upper cavity of piston of atomiser drive. Switching-over of gas distributor from one position to another is performed by control system.
EFFECT: simplifying the design of fuel equipment of internal combustion engine.
