Eli5: Why is fuel/petroleum the liquid that makes cars run? What’s happening inside the car with this specific liquid that makes it go that can’t happen with other liquids?
In: Technology
The piston pulls fuel and air into the cylinder, and when the piston moves up, it compresses the fuel/air mixture, then the spark plug lights causing the flammable mixture to explode, pushing the piston down and sucking the exhaust out of the exhaust valve.
Diesel fuel runs different in diesel motors, but that’s a basic example of how a gas engine works
