Find out everything about engine cleaning

Carbon cleaning is a process of removing soot, or carbon, from your engine. These deposits, made of unburnt hydrocarbons end up clogging your engine as well as other parts such as the EGR valve, Particulate Filter or even the turbocharger.

The FlexFuel solution: Carbon cleaning via hydrogen injection

Engine carbon cleaning by FlexFuel hydrogen injection is produced by improving a natural phenomenon of enriching the air-fuel mixture in your combustion engine. Our solution is efficient and non- aggressive, as it does not introduce any chemical or corrosive products into your engine. The carbon is simply dissolved inside the engine and naturally evacuated with the exhaust gases where it is collected by a special filter.

After the treatment, your vehicle will regain its original performance!

New! Carbon cleaning interface thanks to Hy-Carbon Connect

A technological innovation, Hy-Carbon Connect offers new functionality allowing a personalized and even more efficient service.

With three worldwide patents already registered, Hy-Carbon Connect, the result of four years of Research and Development, is a successful solution to the problems of clogged engines.

The Hy-Carbon Connect machine can diagnose the state of your engine and de-scale it using hydrogen injection. This innovation helps reduce the risk of breakdowns, reduces pollution and fuel consumption, creates your driver’s profile and monitors it.

But how exactly does Hy-Carbon Connect work?

The driver’s profile is first determined based on parameters such as annual mileage and driving environment. The Hy-Carbon Connect then independently analyses the clogging status of the engine’s sensitive parts, thanks to algorithms developed by FlexFuel®.

Following the diagnostic, Hy-Carbon Connect performs custom cleaning and sets specific parts in motion throughout the treatment, thereby restoring their original mobility.

After the cleaning, Hy-Carbon Connect produces a before & after report for the vehicle, which is sent to the driver.

Take advantage now from a unique and totally personalized service to bid farewell to problems related to your engine being clogged.

In summary, carbon cleaning by hydrogen injection is a solution which is:

• Robust: our technology was designed in 2008, initially for the industrial world and can withstand rigorous environments.
• Innovative: a dashboard allows Hy-Carbon to be controlled in a simple manner. The EGR Pilot option is an exclusive patented innovation which controls the EGR valve. Everything to guarantee you iron-clad efficiency!
• Economical: zero consumables, so no surprises in operating costs. Furthermore, the station being autonomous, the workforce is free to carry out other hands-on jobs.

Carbon cleaning is the solution that can reduce fuel consumption by up to 15%, reduce emissions by 50% and reduce the risk of a breakdown.

There are advantages to carbon cleaning your car with our patented FlexFuel hydrogen injection machine. This will change the life of your vehicle, improve its performance, driving experience and save you money in the long run.

Regain your vehicle’s original performance

You will find a much healthier engine. The proof for this is those fault codes shown by the diagnostic that are corrected by carbon cleaning.

Say goodbye to hard starting engine, high fuel consumption, low engine performance, dashboard lights, black smoke and sluggish acceleration. Thanks to carbon cleaning, your vehicle will regain its original performance.

Eliminating engine soot restores lost horsepower in your car. Results: more agile driving and an engine that is more responsive in higher gears.

Carbon cleaning = restoring the performance of your vehicle!

Make it easier to pass your MOT Check

Say goodbye to failing your MOT Check on emissions! By regaining its original performance, your vehicle will emit 50% less CO2 at least!

With recent anti-pollution standards, especially measures on exhaust gas opacity, carbon cleaning your engine by hydrogen injection eliminates black smoke and makes passing the Roadworthiness Checks easier.

Whether diesel or petrol, unclogging your engine will emit fewer particulates.

Carbon cleaning = MOT Check passed!

Forget about expensive breakdowns

Almost three-quarters of the faults that occur with the engines are caused by carbon deposits.

New anti-pollution standards and speed restrictions increase carbon deposits in the engine and thus increase the possibility of the appearance of dashboard lights, or more seriously, of breakdowns.

By choosing carbon cleaning by hydrogen injection, you will avoid clogging and replacing expensive parts, such as the EGR valve (around £350), injection pump (around £1,000) or even the turbocharger (up to £2,000).

Carbon cleaning = no dashboard lights ON

Save money everyday by consuming less fuel

And the cherry on top is that your fuel consumption will reduce by up to 15%. With less trips to the petrol station, carbon cleaning your vehicle will save you more money on the long run.

Carbon cleaning = You save money every day!

Reduce pollution

By eliminating scale in all types of engines, you will reduce exhaust gas emissions. Maintenance of the vehicle also plays an important role in eco-driving, economic and ecological motoring, for the good of our planet and your bank balance. By regaining its original performance, your vehicle will emit 50% less CO2 at least!

Carbon cleaning = eco-driving

After carbon cleaning with FlexFuel Energy Development® hydrogen injection, the planet will say “Thanks!” Your bank balance and your vehicle too!

You will understand by now that unclogging your vehicle’s engine has technical, economic and ecological advantages.

The winning recipe: clean your engine at least once a year and you prolong your vehicle’s life.

Depollution of engines by hydrogen injection is a service performed by a garage equipped and trained by us. To find a partner garage, visit our page “Where can I find a garage”.

Your garage equipped with a FlexFuel engine cleaning station by hydrogen injection will offer you the most suitable service for your vehicle.

What types of treatment are on offer from garages equipped with FlexFuel?

The type of treatment* will be defined by taking into account the various data from your vehicle amount of cylinders, mileage, your driving profile and there follows from those a clogging level for your vehicle.

Depending on the level of clogging of your engine, our partner garages trained and equipped with FlexFuel offer several hydrogen injection cleaning packages ranging from simple preventive to curative treatment with full cleaning.
Below is an overview of the two types of treatments *:

Preventive treatment:

Preventive treatment is advised in the context of maintaining your vehicle and prolonging the life of your engine. By preventing excessive clogging, you avoid breakdowns, over-consumption of fuel and loss of performance.

Curative treatment:

Curative treatments, on the other hand, allow treatment of breakdowns and malfunctions linked to the accumulation of carbon in your engine. This treatment also lowers fuel consumption and reduces your polluting emissions.

FlexFuel® de-scaling by hydrogen injection allows not only the unclogging of your engine, but also parts such as the Particulate Filter,  turbocharger, EGR valve or even the injection system.

* The choice of one or the other of these services depends on your vehicle’s clogging level.

What are the applicable charges per treatment type?

The price of your carbon cleaning thus depends on the chosen type of treatment and parts needing to be cleaned, your vehicle’s engine type, but also the required treatment time for efficient unclogging.

According to the type of treatment, the maximum recommended retail prices range from £69 include all taxes and £299 include all taxes.
