ENGINE Russian patent published in 2008 - IPC F02B53/00 

FIELD: engines.

SUBSTANCE: invention relates to propulsion engineering and compressor engineering and can be used as a vehicle drive. Engine is equipped with oil duct pump system, bilateral floating pistons with unilateral rectangular side slots and bilateral distribution shaft, located eccentrically relative to the compressor and engine cases. The compressor case is located eccentrically relative to the engine case, their pistons are balanced by 180° turn relative to each other at the distribution shaft. Rotors are mated with the pistons mating planes. Power shaft has disc with stops. Holes mated with the stops are performed in the engine rotor. Slots of pistons have planes mated with the counter mating planes of the distribution shaft, which divides the piston slots in a leak-free manner to the working chambers of pumps and which is installed at the middle end cover with a gap, able to rotate. Inlet-outlet channels are performed in the distribution shaft; these channels provide ability of alternate and automatic connection with the working chambers of pumps. Mains of oil duct pump system have inlet and outlet connectors and holes with grooves, mated with the inlet-outlet holes, located in the slots of pistons and mated with the inlet-outlet channels of distribution shaft and working chambers of pumps.

EFFECT: simplification of design of engine and electric ignition system.
