How do Fuel Injectors work?

Fuel injectors introduce fuel into the engine combustion chamber at a controlled rate. All diesel engines have injectors whilst some older petrol engines (pre 1980’s) use the alternative of a carburettor. Injectors have tiny nozzles that under pressure allow for precise amounts of fuel to be added to the air-fuel
mix ratio which in turn ensures a safe and efficient combustion. Engines by vary of design have either multiple injectors (one per cylinder) or single point injection where there is one injector for all cylinders. For fuel efficiency and emissions benefits, today’s fuel injector works to extremely tight tolerances producing a finer spray that allows for better mix with the air as it enters the chambers. The production of such precise fuel delivery means these injectors are costly and don’t necessarily fail but due to the carbon deposits issue they can become restricted and clogged.


Restricted or clogged injectors reduce the flow of fuel and disrupt the spray pattern which is critical for an even combustion. Uneven spray can cause stuttering acceleration and lack of power. The most common cause of of fuel injector issues is carbon buildup. When this is combined with high temperatures it leads to excessive fuel inside the injector nozzles burning. It’s a known fact that low-quality fuel can worsen such problems.

High Standard of work

Just to say Matts work was to a high standard. He arrived early, focused on the task and did a great job. He completed all tasks required and ran a thorough check afterwards. Very reassuring! A genuine technician and people person. I have no concerns recommending Matt and his company.

I had Technician Cristian Nicolaie come…

I had Technician Cristian Nicolaie come to my home on Friday morning to diagnose and clean my DPF filter and remove carbon build-up from the engine. From the moment Cristian arrived, he was polite, friendly and professional. He asked me a few questions about the car, explained what he was going to do and talked me through the possible cause of the problem. He also gave me some really useful advice on how to help prevent the problem from happening again. Cristian carried out the work professionally and got the car back to normal. The diagnostic test afterwards showed that everything was working as it should. What made this even more important to me was that I was due to go away that day and had to tow my caravan. After speaking with Cristian, he gave me complete confidence that the car was going to be okay — and he certainly didn’t disappoint. I towed my caravan with no problems at all, and the car performed perfectly. I live in the BS15 area, and I would have absolutely no hesitation in recommending Cristian Nicolaie to anyone experiencing problems with their car. If the other technicians within the company have the same level of professionalism, knowledge and customer service as Cristian, then I would happily recommend the company as well.

Full Carbon Clean and remap

I had the pleasure of meeting Matt today. He was on time, gave great advice, honest feedback, great sense of humour - everything you would want from your technician. Never makes you feel stupid. Explained how the remap works. I'm only disappointed he didn't take a picture of my car for his portfolio.

What causes fuel injectors to get dirty and clogged?

WHAT PROBLEMS WILL CLOGGED INJECTORS CAUSE?

How to prevent fuel injectors from getting dirty and clogged?

Primarily use high-quality of fuel, they have better and more cleaning additives in them to assist in keeping engine components clean including:-

  1. Deposit control additives
  2. Antioxidants and stability improver
  3. Cold flow improver
  4. Anti-static additives
  5. Corrosive inhibitors
  6. Detergents
dirty fuel injectors

Premium fuels contain a mixture of additives that unlike standard fuels provide the following benefits:-

  1. keep injectors and other engine components clean

Cleaning your Fuel Injectors

There are numerous ways to clean or replace the Fuel Injectors with varying prices. The costliest option is a complete replacement part. Most mechanics will recommend this – Why? Because they’ll earn a profit from the part and it’s a quicker job for them.

clean fuel injector

The price of replacing Fuel Injectors varies considerably and will obviously depend on how many the engine has, a ballpark figure is between £250 and £1,000 plus labour for fitting.

The moderately expensive alternative is to remove the injectors and manually clean them via an injector specialist, this requires some mechanical skill and time. The problem is not all injectors are so easy to remove and refit, especially for the novice mechanic. As there are no replacement parts involved the cost of this service will be purely based on your mechanics' labour charges so expect a charge of anywhere between £200 – £400.

Our alternative is to try cleaning the injectors before going the expensive route. As long as the injectors are still firing there is a chance cleaning is viable, however, if an injector is stuck in the open or closed position unfortunately our service will not fix this for you.

Faq

Depending on the level of service chosen our engine carbon cleaning service takes a total of 45-60 minutes.

Carbon cleaning is not as such a fix, its original purpose is cleaning as a preventative measure as carbon build-up is the root cause of 85% of the failure of components. If your vehicle is experiencing faults related to a faulty catalytic converter cleaning will if the catalyst is simply dirty resolve the matter. However, if the catalyst has failed or collapsed inside then of course cleaning cannot repair that. Unfortunately, there is no way to determine if the part is simply dirty or damaged without cutting it open to inspect it, which is irreversible and not viable. As replacing the catalytic converters is so expensive many of our clients will choose to try cleaning knowing even if it doesn't resolve the problem at least it’s cleaned the engine so was worth that gamble. As long as you appreciate this is at your own risk and we will not be held accountable if the catalyst issue is not resolved we are happy to try cleaning for you. If a new catalytic converter is required to reduce the risk of further failures we would then recommend an immediate carbon clean and follow-up carbon cleans once every 12,000 miles as a preventative maintenance.

You cannot clean too much but we recommend preventative cleaning once a year, or every 10-12,000 miles – just like a regular oil change but for the air and fuel side of your engine - little and often is the key and as the saying goes… ‘An ounce of prevention is worth a pound of cure!

Certainly not. We are a worldwide brand with CE marked machines, operating in over 50 countries with 100’s of machines being used daily – never has there been an engine damaged from our engine carbon cleaning process.

We would not take any risks with your vehicle, so for piece of mind UKCC Auto Techs guarantee to you that all our technicians are trained to the highest standards and are independently fully insured.

No, this process is totally safe and untraceable.
