Among the car parts that need regular maintenance are your engine's fuel injectors. These play a vital role in delivering and regulating fuel to your cylinders to keep the engine firing efficiently. All cars manufactured since 1990 use fuel injection systems, so understanding how they work can help you with maintenance.

History of Fuel Injection

Before fuel injectors became widely used, cars had a chamber called the carburetor. This car part was where the oxygen and fuel mixed before continuing to the engine cylinder. This system made it difficult to monitor the exact ratio of air to fuel being produced. For emissions-reducing features like the catalytic converter to work correctly, manufacturers needed more precise control.

In 1925, Swedish engineer Jonas Hesselman invented the direct fuel injector. It was used in airplanes during World War II. By the 50s, many automakers adopted it as an alternative car part to the carburetor. The two options coexisted for decades, but with increasing emissions regulations, the auto industry shifted to the more precise fuel injectors.

How Fuel Injection Works

Fuel injectors are valves controlled by your car's electronic engine control unit (ECU). The ECU is hooked to sensors that monitor the airflow into the engine and match it with an appropriate amount of fuel. The injectors then spray the correct amount into the cylinders. The harder you step on the gas, the more air you let into the throttle, and the more fuel the ECU releases.

Why You Need Fuel Injection Service

Over time, your engine firing leaves carbon residue on the fuel injectors and inside the cylinder. These auto parts need to be cleaned to make sure fuel can flow at the right speed and mix thoroughly with the air so it'll ignite correctly. Cleaning them prevents the fuel line from clogging, extending the life of your car and ensuring your vehicle is running at maximum efficiency. You need this service every 60,000 to 90,000 miles.
