ABSTRACT:
The monocilindrical hybrid comprises a boosted by the reciprocating air compressor two-cycle engine and a hydraulic pump. The pump plunger fastened to engine piston and located coaxially with the compressor piston and pump rotor comprised stabilizer hydraulic motor and two diametrically opposite axial rods associated with the plunger, compressor piston and swash plate. The swash plate turn changes the engine piston stroke and remains the engine compression ratio. The swash plate shift changes the engine compression ratio for the either kind of fuel use. The hybrid and pneumohydraulic accumulator association transforms the single pump plunger supply pulsation into uniform fluid flow feeding the hydrostatic transmission motor. Direct energy transmission, variable engine, compressor and pump displacement volume and energy recuperation increases the specific power, decreases the weight and installation space and enables to achieve 80 mile per gallon for the car in city conditions.
