How do modern car engines work?

A gasoline car typically uses a spark-ignited internal combustion engine, rather than the compression-ignited systems used in diesel vehicles. In a spark-ignited system, the fuel is injected into the combustion chamber and combined with air. The air/fuel mixture is ignited by a spark from the spark plug.

How does a car’s engine work?

Basically, fuel enters the engine through an injector. The spark plug then ignites the fuel to release energy. This energy turns pistons in the engine, which makes the crankshaft turn. The energy then transfers to the car powertrain, which spins the wheels for motion.

What makes a car move?

But it’s the piston-powered explosions in the combustion engine that make your vehicle move Most cars use a four-stroke engine, designed by Nikolaus Otto in 1861. This engine has a series of holes, called cylinders, with a piston inside. As the piston lowers, it drags in air and petrol, a mixture of hydrocarbons and additives to protect the engine.

How are modern car engines different from older ones?

Before we talk about how modern car engines are different from older ones, you need to understand the basics of how a car engine works. Basically, gasoline and air are ignited in a chamber called a cylinder. In the cylinder is a piston that gets moved up and down by the gasoline/air explosion. The piston is attached to the crankshaft.
