Free-Piston Diesel-Fueled Linear Alternator for Auxiliary Power Unit Applications

Abstract

Present day internal combustion engines have been proven to be a successful means of converting linear reciprocating motion into rotary motion through the use of a slider-crank mechanism. However, a substantial portion of the mechanical work produced is lost in internal friction due to the presence of moving parts, like the crankshaft. The use of a linear engine to eliminate the crankshaft and other rotating components would eliminate these sources of friction, and hence improve the overall efficiency of the engine. Further advantages of this engine configuration are those of reduced weight and cost, from the reduction of components required. Previous studies of free-piston engine designs have indicated that they would be useful where linear power delivery could be used, such as in fluid power delivery, or in electrical energy applications.
