Summary: | An internal combustion engine is provided with a vacuum pump (17) to remove burnt gases form the engine cylinders during an exhaust stroke. The vacuum applied by the pump (17) is sufficient to remove the gases during an exhaust stroke and also apply a force to lift the piston. A certain amount of torque is therefore generated during the exhaust strokes. In a similar manner and to similar effect a compressor (18) is provided to force fuel into the cylinders during induction strokes and also create a certain amount of positive torque. |
