<p>A belt drive system having a belt having a belt body. A tensile cord disposed in the belt body running along a longitudinal axis. A plurality of belt teeth disposed on an outer surface of the belt body, the belt teeth oriented transverse to the longitudinal axis. A belt land disposed between the belt teeth. A driver sprocket attached to an engine crankshaft, the engine having a plurality of cylinders. A driven sprocket. The number of grooves on the driver sprocket being an integer multiple of the number of engine cylinders divided by two. The number of grooves on the driven sprocket being an integer multiple of the number of grooves in the driver sprocket. The number of belt teeth, land length and sprocket groove spacing is dependent on the number of engine firing events per crankshaft revolution thereby reducing the frequency of the belt/pulley meshing to a level within the orders of engine frequencies.</p> |
