ABSTRACT OF THE DISCLOSURE A drive system is provided particularly for an engine having a plurality of sheaves. It comprises a single endless power transmission belt which has opposed driving portions defined by a flat driving portion and an oppositely arranged driving portion which has a plurality of projections therein. The belt operatively associates with a driving sheave and a plurality of driven sheaves. The driving sheave and at least one of the driven sheaves each have a plurality of grooves therein, each groove being defined by an associated channel-like surface when viewed in cross section. At least another of the driven sheaves has a right circular cylindrical surface. The flat driving portion of the belt engages the right circular cylindrical surface. The projections of the oppositely arranged driving portion are received in grooves of the grooved sheaves and operatively engage the channel-like surfaces. A belt tensioning device is also provided and maintains a controlled tension on the belt during operation thereof.
