ABSTRACT:
A rotary valve assembly will be utilized on internal combustion engines for regulating air-fuel mixture from a carburetor or other fuel injection system entering the cylinders of either two stroke or four stroke spark ignition engines serving to improve the part-load fuel efficiency of such engines by minimizing the pumping losses. This increase in efficiency is accomplished by substituting what is termed "time-duration-modulation" control for the present day "throttled" or "resistive" intake control now used to regulate engine power output. The rotary valve structure employs a hollow, or open sleeve, or tubular multi-port structure comprising the rotary valve, with an outlet for each cylinder, operating at fifteen (15) p.s.i. maximum differential pressure and relatively low temperatures, connected in series with presently used poppet or port type intake valves. Rotary valve timing or phase control is accomplished with a multi-pulley belt drive system.
