A timing belt, or cam belt (informal usage), is a part of an internal combustion
engine that controls the timing of the engine's valves. Some engines, like the
flat-4 Volkswagen air cooled engine, and the straight-6 Toyota F engine use timing
gears. Timing belts replace the older style timing chains that were in common
usage until the 1970's and 1980's (although in the last decade there has been
some reemergence of chain use). The term "timing belt" is sometimes used for
the more general case of any flat belt with integral teeth, although such usage
is a misnomer since there is no timing or synchronization involved.
