These little guys take fuel and spray it into the engine’s cylinders as a very fine mist. They’re electronically controlled, meaning the engine’s computer tells them exactly how much fuel to deliver and when. They’re responsible for atomizing the fuel—basically, breaking it down into tiny droplets so it mixes well with air for efficient combustion. Different engines use different nozzle designs, but they all accomplish the same core task: getting fuel into the engine. It’s a crucial part of the entire fuel supply system. The fuel pump sends fuel to the injectors, and these nozzles deliver it directly into the cylinders where it burns, creating the power that moves your vehicle. They work closely with the engine’s computer and other sensors to maintain the correct air – fuel mixture for smooth running, good fuel economy, and low emissions. Think of it as one of the core ingredients in making the engine run. If a fuel injector fails or gets clogged, your engine won't run properly. You’ll notice if it’s failing usually because you'll get misfires – the engine will run rough, maybe shake a bit. You might also see a drop in fuel economy, or even a check engine light. A bad injector can also cause black smoke from the exhaust. They really act like a shield against incomplete combustion, so when they go bad, things start to suffer.
