Abstract
An internal combustion engine comprises a piston arranged to move reciprocally in a predetermined direction relative to an engine block. A drive shaft is mounted in the engine block and arranged to be driven by the piston in rotational motion about a first axis perpendicular to the direction of motion of the piston. Rotational motion of the drive shaft is transferred to a first shaft that is mounted in the engine block parallel to the drive shaft. Rotational motion of the first shaft is then transferred to a second shaft such that the engine produces a rotational output about an output axis that is parallel to the direction of reciprocal motion of the piston.
