Product description:Most car engines have four cylinders. Inside these cylinders is where you find the pistons.
The pistons move up and down inside these cylinders through fuel combustion.
Fuel is injected into the cylinder and then combusted, forcing the piston to go down.
The combustion is done at a very fast interval in all cylinders.
The piston is connected to a connecting rod which is then connected to the crankshaft.
The crankshaft is designed to convert the up and down motion of the pistons to a rotating motion.
The downward movement of one piston will force another piston to go up, thus,
continuing the up and down motion of pistons and then producing the rotating movement of the crankshaft.
