INNOVATIVE SMALL ENGINE CONCEPTS

THIS PROPOSAL OUTLINES AN SBIR PHASE I ENGINE PROJECT CAPABLE OF DIESEL FUEL OPERATION AND LIGHTWEIGHT CONSTRUCTION. INHERENT SPECIFIC WEIGHT PENALTIES OF THE DIESEL CYCLE BEING INVERSELY PROPORTIONAL TO SPECIFIC DISPLACEMENT, INDICATES A SCALE REDUCTION OF THESE ENGINES DEMANDS GREATER DESIGN DISCIPLINE RELATIVE TO THE PHYSICS THAT GOVERN THEIR PERFORMANCE. THE PROPOSED APPROACH EMPLOYS A COMBINATION OF INNOVATIVE TRANSLATIONS OF ROTARY TO RECIPROCATING MOTION RESULTING IN A COMPACT DESIGN OF HIGH MECHANICAL EFFICIENCY. ADDITIONAL POWER-PRODUCING VOLUMETRIC VALVING CONTROLS SWIRL AND SCAVENGING EFFICIENCY, ENABLING HIGH BMEP LEVELS. HIGH THERMAL EFFICIENCY IS ACHIEVED BY THE INCORPORATION OF LOW SURFACE/VOLUME GEOMETRY. THE DESIGN MAKES EXTENSIVE USE OF SYNERGISM.
