Title: Valve-arrangement for controlling gas in a piston-type internal-combustion engine

Abstract: A valve arrangement for controlling gas exchange in a piston-type internal-combustion engine consisting of an arrangement of valves through which it is possible to optimize the filling of the combustion chamber of the cylinder with the fuel mixture as well as exhaust of the residual gases of combustion. The system includes (provides for) the transfer of the functions of the conventional intake and exhaust valves to additional valves located in the respective intake and exhaust conduits, each of the conduits being open to and communicated with the other in the cylinder head thereby creating a common chamber or chambers (plenum or plenums) through which the respective gas mixtures are directed, permitting a partial, controlled contact between the two gas mixtures, and using the conventional valve system opening directly to the combustion chamber for enhancing the speed and efficiency of charging the combustion chamber with working fluid, sealing the combustion chamber during the processes of compression of the combustible gas mixture and expansion of residual gases of combustion, and increasing the speed and efficiency of expulsion of gases of combustion from said combustion chamber.
