What Is the Purpose of a Timing Chain?


An automobile engine represents a complex interaction of mechanical parts with thermal and chemical reactions that produces the energy necessary to propel a vehicle forward. The most basic process within an engine is the combustion cycle; it is a precise interaction between the camshaft and crankshaft that determines when the combustion cycle takes place in each cylinder. The crank and camshafts work in tandem through a connection created by the timing chain.


A timing chain is the link between the crankshaft and the camshaft that transmits the rotation of the crankshaft to the camshaft, which then causes the opening and closing of the intake and exhaust valves within an engine.
