Gasoline Engines

Gasoline engines turn the energy in fuel into motion that can move a car.

How It Works

Gasoline engines burn a mixture of fuel and air inside cylinders. The expanding gas pushes pistons, which turn a crankshaft.

Why It Matters

The crankshaft sends power through the drivetrain to the wheels. Modern engines use computers to control fuel, air, and timing.
