What Are Fuel Injectors?
A fuel injector sprays fuel into an engine using electronic valves that can open and close many times per second. For optimum combustion and efficiency, they have an atomising nozzle that distributes fuel evenly.
Engines powered by injectors run more efficiently and emit fewer pollutants than those powered by carburettors.
There is usually one fuel injector per cylinder in a car. You will most likely have four fuel injectors if you drive a car with four cylinders.
How Do Fuel Injectors Work?
The fuel injector controls the amount of fuel delivered to the combustion chamber, making sure the right amount is injected at the right time. Each cylinder contains a fuel delivery system that ensures responsive power output and maximum efficiency at the exact moment and quantity.
- Through the fuel lines, the fuel pump delivers petrol or diesel to the injectors.
- Fuel is sprayed into the combustion chamber at the right time by the ECU (engine control unit).
- Through the nozzles, pressurised fuel is sprayed into the combustion chamber when the ECU activates the injector. Small nozzles allow fuel to be atomised, which results in a more efficient burn.
