The invention relates to an internal combustion engine having six strokes or more. It comprises a valve head provided with at least a preheating chamber and at least a combustion chamber associated to at least one variable volume chamber. The preheating chamber is located between an admission duct and the variable volume chamber. The combustion chamber is located between the exhaust duct and the chamber having a variable volume. The admission valves and exhaust valves set in communication or separate, according to their position, the variable volume chamber with the preheating chamber respectively the combustion chamber. The rods of the admission valve and exhaust valve, actuated by cams driven in rotation by cam-shafts, carry movable members of obturation devices, which by cooperating respectively with the fixed members of these obturation devices, provided with slots open or close the connection between the preheating chamber and the admission duct respectively between the combustion chamber and the exhaust duct. |
