What Fuel Injectors Do Fuel Injectors distribute fuel into the engine's cylinders where it's burned to power your vehicle. Injectors have a very specific spray pattern and volume. If this pattern or volume is altered, the injector won’t deliver the proper amount of fuel at the right time. The result is the vehicle will not run properly or at maximum power. Why Maintain Fuel Injectors? Over time, deposits build up on the injector nozzles, adversely altering the spray pattern and injector volume. These deposits may come from additives in gasoline or may be a result of other types of build-up. Fuel injectors need to be part of regular engine maintenance plans so that they perform at peak levels. If not, the result will be poor drivability, reduced fuel economy, higher emissions and overall poor performance. Fuel injectors are small—like precision garden hose nozzles. And just like a garden hose nozzle, the spray can vary from a wide flow to a tight stream. If dirt gets in, the spray pattern will be altered and the hose doesn’t work properly. As injectors get clogged, the car may begin to hesitate, stumble, idle rough or suddenly lose power. It may even become hard to start. So why clean Injectors...because dirty injectors lead to: Increased Emissions Reduced Fuel Economy Catalytic Converter Damage Poor Handling Here’s how “Cleen” injectors affect your vehicle: Improved Engine Performance Reduced Emissions Conserve Energy Save Money at the Pump Remove the deposits and fuel injectors will work like they should. That's why regular fuel injector maintenance is so important. And that’s where the Cleen Plan comes in! Visit our Resource Library for available downloads Back to Cleen Plan
