* Fossil Fuels: These fuels are formed from the remains of ancient plants and animals over millions of years. When burned, they release energy in the form of heat, which is used to power the engine.
* Internal Combustion Engine: This engine works by burning fuel inside a cylinder, creating pressure that pushes a piston. The piston's movement is then used to turn a crankshaft, which ultimately drives the wheels.
However, there are also other types of car engines:
* Electric Vehicles: These cars use electricity stored in batteries to power electric motors that turn the wheels.
* Hybrid Vehicles: These cars combine a gasoline engine with an electric motor, allowing them to switch between fuel types for optimal efficiency.
* Hydrogen Fuel Cell Vehicles: These cars use hydrogen fuel to generate electricity through a chemical process, which then powers an electric motor.
So, the "energy" that runs cars can come from a variety of sources, but gasoline and diesel are still the most common fuels used in cars today.
