1. Gasoline

Gasoline (also called petrol in many countries) is a liquid fuel made from crude oil, used to power internal combustion engines — like those found in most cars, motorcycles, and small trucks.

  • Gasoline is mixed with air in the engine.
  • The spark plug ignites the mix.
  • This small explosion pushes the pistons, creating power to move the car.
  • Produces carbon dioxide (CO₂) and other emissions.
