FIELD: engines and pumps.
SUBSTANCE: engine includes a hollow stock that connects pistons, is equal to the diameter of the pistons and provided with curved closed grooves of a semi-round cross-section, which interact with semi-round contact end faces of rollers mounted on needle and thrust bearings in hubs of cylindrical gears enveloping the stock, connected to a power takeoff shaft through coupling and matching cylindrical gears, which considerably cheapens the drive and improves its mechanical efficiency. Use of a hydraulic drive at removal of combustion products and a pneumatic inertial air inlet system to a working cylinder reduces consumption of thermal energy for gas distribution. When atomised liquid fuel is sprayed into a prechamber with arrangement of a vortex turbulent flow in the chamber and burnt, it considerably increases homogeneity of the mix, thus contributing to complete combustion.
EFFECT: reducing wear of movable parts; improving mechanical efficiency.
