"GEFRA" ADIABATIC COMBUSTION ENGINE ABSTRACT All internal combustion engines suffer from poor thermal efficiency. This invention centres around novel design ideas which prevent thermal losses or recover heat for reuse in the combustion process. In addition, frictional losses are kept very low by limiting the number of moving parts to the absolute minimum necessary to operate the engine. Light weight parts and the absence of cooling media with all their mechanical components account for a much improved power to weight ratio. The invention consists of a modified two cycle internal combustion engine of radial design. Cylinders are arranged around a central crankshaft on which all the piston-connecting rod units share a common journal. Dual purpose cylinders, with their respective piston- connecting rod units, are instrumental to recapture waste heat from the combustion process for recycling. The modular design of the cylinder piston units has the advantage that a standard housing can be fitted with the number of cylinders to meet different power requirements. GEFRA Engine Inv.
