Description
Description
The clue is very much in the name, it’s a device that directly injects petrol or diesel into the combustion chamber. Fuel injectors use electricity to add the precise amount of fuel needed at every engine cycle.
Located on the top of the engine, the tops and fuel pipes are rarely visible without removing the engine covers and other components. They protrude into the engine's cylinders, similar to spark plugs.
Fuel injectors replaced carburettors. Being controlled by the ECU, fuel injection systems allow for more precise fuel delivery, leading to both better fuel economy and more power.
Using a magnetic coil, similar to an electronic valve, fuel is forced through a small orifice, this allows very precise control of both the timing and capacity of the injection process.
What causes fuel injectors to fail?
Fuel Injectors are complex and intricate components, there are a few ways an injector can become defective, most commonly either due to contaminant buildup or seals ageing and cracking.
Fuel contains trace elements of impurities such as carbon, these can get trapped inside the injector over time, and cause issues preventing the injector from opening or closing, both resulting in running problems.
Time is not kind to any component with rubber seals, these will gradually dry out and begin to be less effective. Injectors have multiple seals, inside and sealing to the engine, and they can begin to leak over time.
Poor fuel filtration
Cars are fitted with a fuel filter, which stops any larger particles that may have been transferred into the liquid through transport and storage.
If your filter is particularly old or of inferior quality, it may allow more contaminants to enter the fuel system. The fuel injectors will always respond poorly to fuel with contaminants.
How long do fuel injectors last?
Typically fuel injectors should last between 60,000 and 100,000 miles. This may be less if the car has been left unused for large periods of time because the seals in the injectors will age faster if not used.
