Abstract:
A chain drive having a phaser such as a hydraulic vane phaser interposed between a timing chain and a driving or driven shaft is provided. The phaser or the vane are controlled to oscillate more at certain engine speeds to thereby reduce the tensioning force on the chain at the certain engine speeds.
