How a Car Engine Works

A car engine is a complex machine that converts the chemical energy of gasoline into mechanical energy that powers the wheels. The basic components of a car engine are the cylinders, pistons, crankshaft, and camshaft. The cylinders are where the gasoline is burned, and the pistons are what move up and down inside the cylinders to create power. The crankshaft is connected to the pistons, and it converts the up-and-down motion of the pistons into rotary motion. The camshaft is connected to the crankshaft, and it opens and closes the valves that allow the gasoline and air to enter and exit the cylinders.
