<p>A reciprocating internal combustion engine is proposed that allows a better exploitation of the energy delivered, produces less polluting emissions and is suitable for utilizing alternative fuels; the engine comprises at least one main piston (5; 53) sliding in a cylinder (4, 52) and operatively connected to a crank-shaft (6) and an elastically yielding head (7; 54) formed by at least one further piston (8; 55) sealingly sliding in the cylinder (4; 52), opposed to the main piston (5; 53), and subjected to the action of opposed first and second elastic means (18, 25; 57, 58) with balanced pre-loads. <IMAGE></p> |
