Remote Controlled Non-Gasoline Burning Water Craft

"Current DoD policy prohibits the procurement of future combat systems dependent on gasoline type fuels, while simultaneously Congress strongly supports DoD acquisitions that are based on Commercial off-the-shelf solutions. Commercial recreationalequipment such as Personal Watercraft and outboard motors have high-speed performance, fitted with optimum lightweight, compact, efficient transmission and propeller designs. Near term federal regulations mandated by the EPA have influenced PWC andoutboard manufactures to convert high-end 2-cycle gasoline powerplants to Direct Cylinder Fuel Injection. (i.e.: OMC-FICHT or Mercury orbital). These spark injection (SI) technologies have greatly reduced the emissions of 2-cycle engines operating ongasoline, but are limited in performance on kerosene based fuels such as Diesel #2. This proposal outlines a true multi-fuel compression ignition (CI) technology that operates at speeds comparable to existing gasoline SI engines up to 8,000 RPM. Thebrake mean effective pressure (BMEP) of the CI cycle is 75-80% of the SI cycle at the same RPM. Therefore the proposed approach operates at high speed on multi-fuels enabling direct injection with a comparable specific output. Since the CI cycle isimmune to detonation of low octane kerosene fuel, higher power is immediately available through the adoption of some form of supercharge. Both military and commercial applications will benefit directly with a
