The 5 most important reasons for the wear of injection nozzles

Just like the human body, your car's engine needs various organs to function properly. One of these organs is the fuel injectors, which mix fuel and air and inject it into the combustion chambers. The injectors can wear out over time, resulting in reduced engine performance, increased emissions and even breakdowns.
What are the causes of fuel injector wear?

1. Contaminated fuel: If the fuel filter is not working well enough or the fuel is refuelled at contaminated filling stations, the injectors can become clogged and wear out. Contaminated fuel contains deposits that lead to clogging of the injector needle and the spray holes. This distorts the spray pattern of the injection nozzles, resulting in unstable combustion and loss of power.

2. Inferior fuels: The use of cheap and inferior petrol or diesel can contain additives that can damage the injectors. These additives can cause the injectors to wear out over time and no longer fulfil their function.

3) Overheating: When the engine overheats, the injectors are also exposed to extreme heat. This can lead to expansion and deformation of the metal parts of the injectors. Deformed injectors cannot atomise the fuel-air mixture properly and reduce engine performance.

4. Mechanical wear: Injectors are constantly moving parts and can wear out over time. This wear can cause the injector needle and spray holes to enlarge and deteriorate. Worn injectors leak fuel and can make an irregular hissing noise when the engine is running.

5. Lack of maintenance: If the injectors are not cleaned and maintained regularly, they can become clogged and wear out. Following the maintenance programme recommended by the manufacturer of your vehicle will ensure a long service life for the injectors and optimum operation of your engine.

Some signs that the injectors are worn are as follows
* Irregular hissing noise when the engine is running
* Loss of power and low traction
* Increased emissions
* Starting difficulties
* Instability of engine idling

If you notice any of these symptoms in your vehicle, you should have your fuel injectors checked and, if necessary, cleaned or replaced. Early diagnosis and early intervention can prevent more serious failures and costs.
How to extend the service life of the fuel injectors:
* Use quality fuel.
* Change the fuel filter regularly.
* Follow the maintenance programme recommended by the manufacturer of your vehicle.
* Have the fuel injectors cleaned or replaced by a professional service centre if necessary.

The condition of your fuel injectors is important to the overall performance and emission levels of your vehicle. By following these simple tips, you can extend the life of your fuel injectors and keep your vehicle running optimally.
