What are fuel injectors and how do they work?

Fuel injectors are electromechanical devices that atomize and spray fuel into an internal combustion engine. They work by pressurizing the fuel and controlling the flow of fuel into the engine to mix with air and create a combustible mixture. The fuel is delivered into the engine through a series of small nozzles, which spray the fuel into the engine in precise quantities based on the engine's demand for fuel. The injectors are controlled by the engine control unit (ECU), which uses information from various sensors to determine the appropriate amount of fuel to be delivered into the engine. The ECU then sends a signal to the injector to open and release a specific amount of fuel into the engine. This process occurs multiple times per engine cycle and is critical to the engine's performance and efficiency.

In even simpler terms: Fuel injectors are small parts in your car engine that help spray fuel into the engine so it can mix with air and burn to create energy. They work like little squirt guns that make sure the right amount of fuel gets into the engine at the right time. When you turn on the car, an electric signal from the computer opens the fuel injector and sprays a fine mist of fuel into the engine. This helps the engine run smoothly and efficiently, and helps you drive your car!
