ABSTRACT:
A rotary commutator valve that is located at the exhaust ports of the cylinder of an internal combustion, reciprocal engine for regulating the flow of exhaust and allowing the exhaust ports to be sequentially utilized as supplementary intake ports for charging the engine cylinder, the communtator valve having an exhaust passage, an intake passage and a common exhasut/intake passage that communicates with the exhaust ports and a rotor with a rotor notch that sequentially and selectively connects either the intake passage or the exhaust passage to the common exhasut/intake passage allowing the exhaust ports to first exhaust combustion gases and then form supplemental intake ports for admitting additional air.
