Abstract
A power supply system comprises an internal combustion engine (100) and an electric motor-generator arrangement that is coupled to the internal combustion engine. The internal combustion engine (100) has a piston-cylinder assembly in which the toroidal section-shaped piston (122) and cylinder (120) are each arranged to rotate, in use, about a common axis of rotation B with respect to a stator arrangement (129) of the associated motor-generator arrangement so as to generate an electric output. The piston (122) and cylinder (120) are also arranged to form a mass-elastic system that is capable of resonance and further arranged such that combustion in the combustion chamber (121) formed between the cylinder (120) and piston (122) can cause the piston (122) and cylinder (120) to oscillate relative to each other about their common rotational axis B.
