The invention is a further development of piston technology in automotive construction and is designed to save fuel. The known pistons are connected to the connecting rod by means of a continuous pin in such a way that the length of the piston/connecting rod unit remains virtually constant. The result is that, in the lower engine speed range of a carburettor engine, when only a small amount of mixture is drawn in, the compression is insufficient. If, on the other hand, as provided by the invention and illustrated by the figures (1 and 2), springs are fitted in a particular way instead of the continuous pin, the compression in the lower engine speed range can be adjusted to a higher level without becoming too high in the upper speed range. As a result, carburettor engines require less fuel. However, in addition, the springs also have the effect that the exhaust gases are expelled more completely and that the fuel mixture is drawn in more efficiently. Furthermore, the springs take up inertia forces of the piston at the dead centre positions and subsequently release these again. These properties have an advantageous and fuel-saving effect in fuel-injected engines too. <IMAGE>
