There are too many to list. As a rule of thumb, belts are used more often on OHC engines, and rarely on OHV engines. But chains are used on OHC engines, even engines that once used belts. The Honda 2.2 4 cylinder is an example. It used a belt up to 2002. After that is uses a chain. But Every manufacture uses chains and belts.
