Cars have an engine. That is the powerhouse of the vehicle. Inside the engine, a fuel injector mixes the gasoline with some air and sprays it into a cylinder where the piston resides. Depending on engine size, the engine fires either 4, 6, or 8 pistons in a cycle, using electricity supplied to spark plugs that project into the end of the cylinder to ignite the gas/air mixture and creates a mini explosion inside the cylinder. This is the internal combustion, harnessing the power of fire. The pistons move up and down in the cylinder with these explosions, and they are attached to a rocker arm inside the engine chassis, which is connected to a gear that turns the crankshaft. The crankshaft couples to the axel with more gears and makes the wheels turn. In addition, there are different sets of gears inside the engine to transfer maximum power depending on the speed of the vehicle. Older cars shifted these gears manually (manual transmission) using a clutch pedal. Newer cars, almost all of them nowadays, have automatic transmissions that do the gear shifting automatically. The engine gets hot from the internal combustion, so a cooling system is used with antifreeze, where the liquid circulates around the engine in pipes and carries the heat away to the radiator, where the heat is transferred to the air.
