THE ORBITAL ENGINE

Over the past ten years the orbital engine has been developed to the point where it is a viable alternative to the automotive reciprocating internal combustion engine. The engine is approximately one third the size and weight of reciprocating engines of similar displacement and power output. The development history is discussed, including details of some of the major problems already overcome to achieve good durability, gas sealing, and performance. Current work is concentrated on combustion, including a novel combustion principle called orbital staged combustion (osce) which capitalises on the unique inherent chamber gas motion, and gives exceptional performance benefits. For relatively minor expenditure and with the engine still in an early stage of development, performance levels are comparable with, or superior to, similar displacement reciprocating engines. Full test results are presented and compared with these engines. In automotive applications the orbital engine will provide an appreciable fuel economy advantage due to its efficiency, light weight and ability to allow for better vehicle aerodynamics.
