ABSTRACT:
An engine apparatus for an internal combustion engine which includes a first rotary valve having an indentation adapted to open an intake passage to allow air to be introduced into a combustion chamber, and a second rotary valve having an indentation to allow exhaust gas to flow from an exhaust chamber to an exhaust passageway. A first mode changer can be utilized to vary the open position of the first rotary valve, and a second mode changer can be utilized to vary the open position of the second rotary valve. A seal member can be used in lieu of either mode changer or two seal members can be used in lieu of both of the mode changers.
