We propose to improve the fuel efficiency of internal combustion engines through a redesign that removes the slider crank mechanism, valves and associated camshaft - the main sources of friction in existing reciprocating piston internal combustion engines. The proposed design is based on a swing piston engine which has clear advantages over the current reciprocating piston internal combustion design in that it has no requirement for valves or camshaft, and has direct rotational motion creation. Even with these advantages however, no viable design has made it to production. The historical failure of the engine is due to the mechanical geared mechanism that provides the requisite motion of the rotating pistons around the combustion chamber. Until our invention, these geared mechanisms where all based on mechanical linkages which could not withstand the alternating shock loadings during engine operation and which quickly led to their destruction, resulting in the inoperability of the engine. Our patented design uses electrical machines to provide coordinated rotation of the pistons, no mechanical linkages are used to affect the rotation of the pistons. The proposed engine design will do away with the high friction components, and ensure the viability of a cheaper, simpler, more fuel efficient internal combustion engine. 
We anticipate that development, commercialisation and market adoption of our engine into portable/stand-by generators serving construction and mining industries and subsequently by the automotive industry.
