ADVANCED LIGHTWEIGHT DIESEL ENGINE

THE PRIMARY OBJECTIVE OF THIS RESEARCH IS TO ESTABLISH A DESIGN FOR A LIGHTWEIGHT, 25 HP, DIESEL FUEL ENGINE THAT WILL PROVIDE GOOD FIELD PERFORMANCE, INCLUDING LOW TEMPERATURE STARTING. ADDITIONAL OBJECTIVES ARE TO PROVIDE A HIGH POWER-TO-WEIGHT RATION, A QUIET AND COOL EXHAUT, IMPROVE EFFICIENCY AND MULTI-FUEL OPERATION. THE PROPOSED APPROACH WILL IDENTIFY REQUIRED MODIFICATIONS TO THE MIGRATING COMBUSTION CHAMBER, FULL EXPANSION ENGINE FOR DIESEL FUEL OPERATION. THIS ENGINE USES ONLY THREE MOVING PARTS, OPERATES ON A UNIQUE, HIGHLY EFFICIENT, PATENTED, OPERATING CYCLE AND HAS A ZERO PRESSURE, QUIET AND COOL EXHAUST (WITHOUT A MUFFLER). THIS TYPE OF ENGINE HAS ALREADY DEMONSTRATED HIGH TOLERANCE TO DETONATION WITH LOW OCTANE FUELS INCLUDING N-HEPTANE. ALSO A SMALL .4 HP ENGINE OF THIS TYPE HAS OPERATED ON DIESEL AND JP-8 FUELS WITH EXCELLENT PERFORMANCE AT A STABILIZED OPERATING TEMPERATURE. THE PROGRAM WILL EVALUATE: ATOMIZATION TECHNIQUES, VARIABLE EFFECTIVE COMPRESSION RATIO, SURFACE-TO-VOLUME METHODOLOGY, AND IGNITION SOURCE. COMPUTER LAYOUT AND MODELING WILL SUPPLEMENT THE ANALYSES. A THREE VIEW ENGINE DESIGN LAYOUT WITH PROJECTED PERFORMANCE PARAMETERS WILL BE ESTABLISHED. PARTIAL HARDWARE FABRICATION AND TESTING WILL ALSO BE PERFORMED TO VERIFY THE APPROACH FOR A PHASE II FABRICATION AND TEST PROGRAM.
