| 20110100309 | Ultra-efficient hydraulic hybrid drivetrain and method of operation - 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. | 05-05-2011 |
