Abstract

Proposed are novel reciprocating-piston internal combustion engines in which, in operation, the kinetic energy of the oscillating masses is buffered as potential energy at the dead centers where the braking and acceleration forces are greatest, in order to thereafter be utilized for re-accelerating the oscillating masses. In this way, the majority of the acceleration and braking work is no longer done by the mechanical parts but by gas forces, so that the friction power losses are reduced and the mechanical efficiency is improved. In addition, the engines can all be designed to have extremely long strokes, such that their thermal efficiency is also improved on account of reduced wall heat losses. A more favourable efficiency results overall from these measures. In some engine concepts, the buffered potential energy can be discharged from the engine in the form of compressed air and stored in a compressed air accumulator, so that when using the internal combustion engine in a vehicle, braking energy buffering is possible. The stored compressed air can likewise be used to start the engine.
