TOWARDS FREE PISTON ENGINE APPLICATIONS
Proceedings of the JFPS International Symposium on Fluid Power, 2002 A hydraulic free piston engine (HFPE) combines a diesel engine and a hydraulic pump into one compact component. The piston assembly motion is influenced by pressures and inertia forces only and no mechanical linkage control the motion. The piston assembly moves during operation linearly back and forth between dead centres by means of the fuel energy ...
