We just learned about the Crankshaft.
Another part of a car's engine is the Timing Belt, Timing Chain or Cambelt.
We know that the Crankshaft spins around with the up and down movement of the pistons,
and the Camshaft spins around to open and close the intake and exhaust valves.
Both the Crankshaft and the Camshaft need to spin at exactly the same time so that the valves open and close while the pistons are going up and down.
The timing belt is wrapped around both the crankshaft and camshaft to make sure they move at the same speed so the valves and pistons are all moving at the right time together.
