Want to avoid replacing your fuel injectors? Got clogged injectors?
Our diagnosis and 2-stage engine carbon cleaning is your best option!
What causes fuel injectors to get dirty and clogged? The biggest cause of clogged injectors is the fuel that they are designed to spray. However, surprisingly it’s not dirt within the fuel that causes the damage. The chemical formulation of the pump fuels we use today has evolved to become a selection of hydrocarbons. These hydrocarbons generate more power but have a nasty repercussion of leaving deposits behind in the injector which clogs it, and on the injector tips which reduces the quality of the spray pattern. Engine heat encourages the deposits to evaporate the fuel leaving the deposits to bake onto the surfaces. Of course, the quality fuel manufacturers use detergents in an attempt to prevent these deposits from building up but with today’s stop-start city traffic the detergents cannot keep up and eventually the deposits win the battle.
How do we clean the injectors? Firstly we’ll use our dealer level diagnostics equipment to assess the engine management error codes and complete live data analysis. Then assuming the vehicle is fit for cleaning we use a minimum of our 2-stage carbon cleaning system that includes our world-leading Hydrogen carbon cleaning and our unique chemicals. Our carbon cleaning machine pulses Hydrogen in through the air intake, during each cylinder combustion over the next 30-45 minutes the Hydrogen will attack the deposits on the tip of the injector, effectively burning them away. As the Hydrogen doesn’t reach into the injectors we use our own specially formulated injector cleaner through the fuel system that will at the same attack and safely break down the deposits within the injectors.
This means in the majority of instances there is no requirement to remove the injectors for cleaning or replace them. On completion of the job, which takes approximately 45-60 minutes, we’ll reassess the engine management system and reset any fault codes.
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 carburetor. Injectors have tiny nozzles that under pressure allow for precise amounts of fuel to added to the air-fuel mix ratio which in turn ensures safe and efficient combustion. Engines by variation 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 work to extremely tight tolerances producing a finer spray that allows for a better mix with the air as it enters the chambers. The production of such precise fuel delivery means these injectors are costly and they don’t necessarily fail often but due to the carbon deposits issue it is possible for them to become restricted and clogged.
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 keeping engine components clean including:-
- Deposit control additives
- Antioxidants and stability improver
- Cold flow improver
- Anti-static additives
- Corrosive inhibitors
Premium fuels contain a mixture of additives that unlike standard fuels provide the following benefits:-
- keep injectors and other engine components clean
- improved performance by keeping the engine running efficiently
- keeping emissions down
- vibration and noise reduction
What problems will clogged injectors cause?
Restricted or clogged injectors reduce the flow of fuel and disrupt the spray pattern which is critical for an even combustion. An uneven spray can cause stuttering acceleration, lack of power and increased emissions. The most common cause of fuel injector issues is carbon build up. 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.
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 parts and labour of the job which includes the complicated job of coding them into the vehicle. The price of replacing fuel Injectors varies considerably and will obviously depend on how many the engine has, a ball park figure is between £400 and £1,000 plus labour for fitting.
The moderately expensive alternative is to remove the injectors and manually clean them with a injectors specialist solution. This requires some mechanical skill and time or for them to sent away to a specialist for reconditioning. The problem is not all valves are so easy to remove and refit. The cost of this service will be anywhere from £150 – £500, if reconditioning it’s often not much cheaper than completely new injectors!
The most cost-efficient solution is our 2-stage (or higher depending on your vehicle specification) carbon cleaning service.
Preventative cleaning starts from as little as £89.99 (for a car)
If your vehicle has an injector issue and therefore requires further assistance to resolve the problem there is no better alternative than a skilled UKCC technician providing our 2, 3 or 4-stage carbon cleaning service.
From just £119.99 (for a car). The advantages are:-
- Our Mobile Carbon Cleaning Technicians come to you
- Potentially no expensive parts
- No disassembly is required, therefore no expensive labour
- Completed in an average of 45-60 minutes so no requirement to leave your vehicle with a garage for days on end
- We are fully insured to complete this service at the roadside or wherever your vehicle is located
