Fuel injection - The most commonly used way of delivering fuel into the engine's cylinders these days. In older cars, fuel and air are mixed in carburettors before being burnt in the engine, but in new cars, the mixture is squirted in (injected) under high pressure.
This helps make modern engines more efficient and produce lower emissions. In direct-injection cars - petrol and diesel - a fine spray of fuel is squirted in before being mixed with air.
