How Do Fuel Injectors Work?
Fuel injectors control the volume of fuel delivered to the combustion chamber, ensuring the right amount is injected at the right time. The process is:
The fuel pump pushes petrol or diesel through the fuel lines to the injectors.
The ECU (engine control unit) uses sensors to work out the right time to fire the injectors and spray fuel into the combustion chamber.
When the ECU activates the injector, pressurised fuel is sprayed into the combustion chamber through the nozzles. Because the nozzles are so small, the fuel is atomised, which makes itburn more efficiently.
Maintaining Fuel Injectors
The simplest way to clean and maintain fuel injectors is by using Redex fuel system cleaners. Available for both petrol and diesel engines, our range of specialist cleaning products remove particles from the fuel injectors which may be causing a blockage.
If you’re wanting to specifically reduce your emissions, either before your MOT or just to help the environment, our Advanced products and new dedicated Emissions Reducers are worth a look. Watch the video below to learn more about how Redex can help keep your car’s injectors clean and clear.
