How does a car operate?

basically, when you turn the key it sends an electric current from the battery to the starter which essentially "turns" the engine over. Then gas is sent into the cylinders where a spark from the spark plugs ignites the gasoline causing the cylinder "hammers" to move which sends power to the wheels eventually. While the car is running the battery is being charged by the alternator and the oil from the engine is sent through the radiator where the radiator cools off the oil and the radiator fan cools off the engine cavity
