Abstract
A hybrid drive system has two sources of driving power: a non-combustion drive system to provide mechanical torque and rotation to a driveshaft, and an opposed-piston, internal combustion engine configured to provide energy for the non-combustion drive system.
Claims8
A hybrid drive system, comprising:
- an opposed-piston, internal-combustion engine comprising a first crankshaft, a second crankshaft, a mechanical connection interlinking the first crankshaft and the second crankshaft, at least one cylinder, and a pair of pistons disposed in a bore of the cylinder for opposed sliding movement therein, a first piston of the pair of pistons being coupled to the first crankshaft and the second piston of the pair of pistons being coupled to the second crankshaft;
- a power transducer device coupled to be driven by the opposed-piston, internal combustion engine;
- and,
- a hybrid powertrain system configured to receive power from the power transducer device;
- in which the hybrid powertrain system comprises a first electric motor/generator device and the power transducer device comprises a second electric motor/generator device and a third electric motor/generator device;
- and,
- in which a motor shaft of the second electric motor/generator device is coupled to the first crankshaft, and a motor shaft of the third electric motor/generator device is coupled to the second crankshaft.

A hybrid drive system, comprising:
- an opposed-piston, internal-combustion engine comprising two crankshafts, at least one cylinder, a pair of pistons disposed in a bore of the cylinder for opposed sliding movement in the bore;
- a first power transducer with a motor shaft coupled to provide mechanical torque and rotation to one or more wheels of a vehicle;
- a second power transducer adapted to convert mechanical rotation of the crankshafts to power;
- and,
- a power storage device coupled to receive and store power from the second power transducer and to provide stored power to the first power transducer.
2 more elements
A range-extended drive system, comprising:
- a driveshaft;
- an electric driving device configured to provide mechanical torque and rotation to the driveshaft, and
- an opposed-piston, internal combustion engine with two crankshafts, and configured to provide electrical energy for the electric driving device to an electrical energy-accumulating device configured to supply power to the electric driving device;
- in which the opposed-piston, internal combustion engine further comprises at least one motor/generator adapted to convert mechanical rotation of the crankshafts to electrical power;
- and,
- in which the range-extended drive system further comprises a control mechanization configured to cause the at least one motor/generator to crank the opposed-piston engine for starting the opposed-piston engine.
