The system also includes a cam shaft having an open cam and a close cam disposed thereon. An open rocker arm is also provided which has an open roller disposed to engage the open cam. The open rocker arm is operatively connected to the poppet valve so as to move the valve from the closed position to the open position when a high lift portion of the open cam engages the open roller. A close rocker arm is provided which has a close roller disposed to engage the close cam. The close rocker arm is operatively connected to the poppet valve so as to move the valve from the open position to the close position when a high lift portion of the close cam engages the open roller. An open hydraulic lifter is pivotally connected to the open rocker arm and operable to hold the open rocker arm in operative connection with the poppet valve.
