The invention is an improved internal combustion engine having a crankshaft, an accessory, a motor/generator, and a belt-drive system. The belt drive systems includes a crankshaft pulley, an accessory pulley, a motor/generator pulley, a belt tensioner, a belt tensioner pulley, and a power transmission belt trained about the crankshaft pulley, the accessory pulley, the motor/generator pulley, and the belt tensioner pulley. The tensioner pulley contacts the belt at a start-slack-side span. It is improved by the tensioner being asymmetrically biased in a direction tending to cause the power transmission belt to be under tension. |
