Small, Heavy Fuel, Compression Ignition Small UAV Engines

"The OPOC JP8 engines for OAV's planned as a standardized 1.2hp to 12hp family, are two-stroke Compression Ignition engines, consisting of opposed cylinders, each having two opposed pistons. All pistons are connected to a single crankshaft located betweenthe two opposed cylinders by unconventional (long=low friction) connecting rods. Intake and Exhaust ports are located at the ends of the cylinder. These ports provide the necessary uniflow cylinder scavenging (there are no valves or camshafts). Thecrankshaft journals, which control the position of the pistons, are arranged asymmetrically such that for each cylinder, the exhaust ports open before the intake ports and close before the intake ports. This asymmetric timing is a must and provides forproper exhaust-blow-down and allows intake supercharging.The two-stroke engine has been eliminated by many as a viable future technology, despite its superior efficiency and power density, essentially because of its scavenging problems. The engineering community needs to see proof-of-concept with the OPOCtechnology to change their minds on the two-stroke engine.The OPOC engine will eliminate, current, unsolved two-cycle problems such as lack of precise scavenging, and improve upon two-cycle engine benefits in the areas of efficiency, size, very low vibration, and cost. This project will be the initial phase of aprocess leading to commercialization of the exceptional two-cycle OPOC engine. Throu
