Abstract:
An internal combustion engine includes at least one rotating, oscillating or reciprocating piston (20, 21) in a cylinder (11, 12). Each piston (20, 21) defines with the cylinder (11, 12) a combustion chamber (35). Each combustion chamber (35) has at least one inlet valve (36) and one exhaust valve (37), and a mechanism (40) to periodically open the inlet and exhaust valves. The valves are closed by a gas spring (80, 82) having a closing force proportional to the speed of the engine.
