Abstract:

The hybrid comprises a two-cycle engine, boosted by the engine power compressor and a hydraulic pump. The pump plunger fastened to engine piston and located coaxially with the compressor piston and pump rotor, provide direct energy transmission to the compressor and pump. The plunger and compressor piston, each connected to one of two diametrically opposite axial push rods, of the rotor. The push rods synchronize and balance the pistons, which move opposite directions into underside of the engine piston space. The reducer synchronizes the separate rotors motion, activate engine and compressor camshafts and conventional accessory units. The engine can be high power started and restarted irrespective of parking time. Because of direct energy transmission the hybrid increases efficiency and specific power, while minimizing the weight, installation space and fuel consumption necessary in particular for automobile hydrostatic transmission.

Abstract:

The universal hybrid () comprises a two-cycle engine (), boosted by the engine power reciprocating compressor () and a hydraulic pump (). The pump plunger () fastened to engine piston () provide direct energy transmission to the compressor and pump. The plunger and compressor piston () moving in opposite direction coupled each to one of two diametrically opposite rotor's () axial rods, which double-sided interact with the pivotable swash plate (). The swash plate turn provides simultaneously the engine, compressor and pump variable displacement volume with engine invariable compression ratio while the swash plate turn axis fixed. This increases the engine power range using the minimum specific fuel consumption. The swash plate turn axis shifting provides the engine compression ratio change for the either kind of fuel use. This combined factors provides the progressive hydrostatic transmission use instead of widespread automotive engine and automatic transmission, thereby minimizing the weight, installation space, cost, labor and fuel consumption.

Abstract:

A compact hydrostatic energy recuperation system comprises hydrostatic converter with first and second pump-motors, which shafts fastened by coupling. The first pump-motor having greater displacement volume associated with the machinery working equipment hydraulic system by hydraulic distributor. The second pump-motor associated with the pneumohydraulic accumulator by two-position valve. The hydrostatic converter increases the working equipment pump suction oil pressure and the pump specific power. The hydrostatic converter charges the pneumohydraulic accumulator with boosted oil pressure and smaller oil volume magnitude during the working equipment lowering and considerable decrease the energy recuperation system installation space, weight and cost. The hydrostatic converter provides the pneumohydraulic accumulator discharge and transmitted this additional energy to the working equipment pump during the most energy consuming load lifting process. This realizes the automatically working energy recuperation system great potentiality of the fuel consumption and toxic exhaust decrease.

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.

Abstract:

Ultra efficient hydraulic hybrid drivetrain of vehicle with a single cylinder module of engine, air compressor, hydraulic pump and motor transmit power without crankshaft, pipes and hoses. The engine piston fastened to pump plunger located within rotor comprised two diametrically opposite axial rods associated with the plunger, compressor piston and swash plate. This plate turn and independently shift by digital control changes the engine piston stroke, changes the engine compression ratio for super efficient homogeneous charge compression ignition and either kind of fuel use. The hybrid by hydraulic accumulator provides start, idling and work mode of operation. Compressor's piston diameter greater than engine piston diameter and plunger pumping fluid and simultaneously driving additional plungers enables to provide more than 130 hp per liter engine displacement. Such unique features and energy recuperation enables to achieve 80 mile per gallon for the 1500 kg weight medium car in city conditions.

Abstract:

A front loader using smaller capacity engine, due to energy recuperation, while utilizing the same capacity and decreasing fuel consumption and toxic exhaust bulk. The front loader uses energy recuperation both when excavating material and upon movement with simultaneous lift of a loaded bucket. The front loader uses energy recuperation irrespective of the type of transmission to the loader wheels. The front loader uses a single crank control, without throttle control, hydraulic distributor of bucket turn, hydraulic distributor of boom lift, and displacement volume of variable pump-motor working equipment.
