<p>The present invention is a system for the distribution of the induction and exhaust flows for four-stroke engines, in which the engine valve/valves (V) are used both for the induction and for the exhaust. The valves (V) remain open from the beginning of the exhaust until the end of the induction; a mechanical system constituted by deviating valves (P), check plates or other elements provides for connecting, alternately, the exhaust pipe (S) and the induction pipe (A) with the engine valves (V). This way it is possible to exploit a greater transfer section between the combustion chamber and the exhaust and induction pipes.</p> |
