What Are Fuel Injectors and How Do They Work?

Fuel injectors are one of the key components of an internal combustion engine. They deliver fuel to the engine cylinders where it will be combusted. The size of the fuel injectors is determined by the amount of fuel that needs to be delivered to the engine. A larger engine will require bigger fuel injectors.

Fuel injectors work by opening and closing very rapidly. When they are open, fuel is delivered to the engine cylinders. The amount of time that the fuel injectors are open is controlled by the engine's computer.

 Fuel injectors replaced carburetors in the early 1980s. Carburetors mix fuel and air together before it enters the engine cylinders. This mixture is then combusted to power the vehicle.

Fuel injectors deliver fuel directly to the engine cylinders where it is mixed with air and combusted. The computer-controlled opening and closing of the fuel injectors allows for a more precise delivery of fuel, which results in better engine performance.
