Abstract
An internal combustion engine, including a piston, a cylinder, and an output shaft, wherein the piston is arranged for reciprocating motion within the cylinder, driven by combustion, and the piston is coupled to the output shaft by a coupling such that said reciprocating motion of the piston drives rotation of the output shaft, the coupling being arranged such that the piston has sinusoidal motion when plotted against rotational angle of the output shaft.
Claims20
An internal combustion engine having a horizontally-opposed cylinder arrangement, including at least one pair of pistons associated with a respective pair of cylinders of the cylinder arrangement, and an output shaft, wherein each piston of the engine is arranged for reciprocating motion within a respective one of the cylinders of the cylinder arrangement, driven by combustion, and wherein the pistons are coupled to the output shaft by a coupling such that said reciprocating motion of the pistons drives rotation of the output shaft, each piston having a sinusoidal motion for constant rotational velocity of the output shaft when plotted against rotational angle of the output shaft, wherein the internal combustion engine includes an intake system comprising a plurality of intake conduits that lead to the cylinders and are arranged to induce cyclonic airflow in a plenum chamber of the intake system, wherein the cyclonic airflow within the plenum chamber provides a ram charging effect to air flowing through the intake conduits.
