A multiple function combined power system an internal combustion engine having a rotational output shaft that is coupled with an electrical machine through transmission gears, belts, or chains constituting a particular transmission device installed between the electrical machine, engine, and output shaft. The electrical machine is a series excited or auxiliary compound excited electrical machine with the electrical characteristic that its rotational speed increases with a decreasing load, or an AC or DC brush or brushless machine able to perform current control, including constant current control to provide a load-following value-added torque function, and is coupled with the engine output shaft through a particular transmission device operated in two system modes following the driving direction of the electrical machine, by means of a one-way clutch and an eccentric clutch in cooperation with control of the rotation directions of the electrical machine to cause (1) the electrical machine to start the engine, (2) the electrical machine to be used as a generator during engine operation, (3) the electrical machine and the engine to drive the load at the same time during the engine operation, (4) the electrical machine to drive the load, and (5) when the load is standing still, the engine to drive the electrical machine in a generator mode to charge the battery or other electrical loads.

A multiple function combined power system, comprising: an internal combustion engine; an electrical machine arranged to be operated through a manual control interface as a motor and generator; first and second one way transmission devices coupled with the electrical machine; at least one of first and second speed responsive clutches connected to transmit power from ends of rotating shafts and arranged to engage and perform transmission above rated speed while releasing and cutting off the transmission below the rated speed; a manual control interface arranged to allow manual input of relevant carrier operating commands; a central controller arranged to perform digital priority calculations on signals from the manual control interface signals or on feedback signals, generate control commands; a drive controller arranged to receive the control commands from the central controller to operate the electrical machine as a generator and control its power generation rate, and to operate the electrical machine as a motor and control its rotation direction and speed, wherein the manual control interface, central control unit, and drive controller include means for carrying out the following functions: (1) the electrical machine is operated by the drive controller to function as a motor rotating in either positive or reverse directions, or to function as a generator for charging the battery or supplying power to other loads; (2) the electrical machine is rotated in positive and reverse directions to provide the following system operations: the motor is rotated in the positive direction to start the engine, and the engine is used to drive loads after it is started while the electrical machine is maintained in a waiting state; (3) while the loads are driven by the engine, if the electrical machine is operated as a generator through the manual control interface, the central controller, and the drive controller, then the engine drives the loads and the generator simultaneously to charge the battery or supply power to the other loads; (4) while the loads are driven by the engine, if the electrical machine is operated as a motor, then the motor is powered by the battery and drives the loads together with the engine; (5) if the electrical machine is operated as a motor and is rotated in the reverse direction, the transmission structure causes the rotation direction of the loads to be the same as if driven by the engine, and the loads are simply driven by the electrical machine operating as a motor while the engine is standing still; (6) while the loads are driven by the engine, energy is recovered by operating the electrical machine as a generator to charge the battery or supply power to other loads, or by using the friction damping of the engine itself for a braking function; (7) while the electrical machine is operated as a motor to drive the loads, energy recovery is achieved by using the electrical machine as a generator to charge the battery or supply power to other loads; (8) the electrical machine is driven by the engine as an AC generator to charge the battery or supply power to other loads.
