An engine drives an ac. generator and the output is passed via a frequency changer to drive motors. The generator-i.c. engine combination (30) is switched, by operating the accelerator pedal (42), to a set load operating point and, by setting the pedal to its stop, the motor idles. The current frequency fed to the motors (5 - 8) is adjusted for the running speed and accelerator pedal position using a microprocessor. The i.c. engine may be an oscillatory piston engine (30) with a linearly oscillating piston, whose offset force is provided by the flywheel action of the generator. A flywheel store (31) may be used to recuperate braking energy to feed it back during acceleration. The connection between drive motor and wheels may be by the use of a single peg planetary gear. |
