Fuel Catalyst Facts

* Fuel catalysts are products that modify fuel to bring about significantly improved combustion

* They are based on the beneficial effects of TIN on hydrocarbon fuels and oils

* They work with petrol and diesel

* They last 250,000 miles on the road or 10,000 operating hours at
sea or in stationary equipment such as heating boilers or generators

They are used around the world in petrol and diesel engines and appliances of all descriptions. They work in absolutely any fuel burning application because they improve the quality of fuel itself

They are fitted either directly into fuel tanks (small engines)

Or plumbed into fuel supply lines between tank and engine (larger engines)

* Smoother performance with extra power
This is typically most evident in smaller less powerful engines and
naturally less evident in an engine that is already smooth and

* Improved economy
Extra power means less fuel used if the extra power not used as extra speed. Innumerable objective tests of fuel catalyst products accounting for variables other than the products have shown fuel savings seldom less than 3% and in many cases up to 10% or more.

When testing for economy it is essential to follow suitable procedures and practices in order to obtain reliable readings

* Less pollution
Innumerable objective tests of fuel catalyst products have concluded there are substantial reductions of toxic emissions including CO, HC, Nox, Particulates and others

* Less carbon = Less maintenance

More thorough combustion also means more energy from a given amount of fuel together with less fuel passing through the engine unburned and hence also reduced toxic emissions

* Reduced work load upon (and hence longer life of) engine and exhaust system components
* Easy starting even after long engines downtimes
* ‘Fuel bug’ in diesel reduced or eliminated
* ‘Waxing’ & ‘Gumming’ in petrol reduced or eliminated
* Cheaper fuel plus fuel catalyst gives performance equal to or better than expensive premium fuels
* Superior substitute for most liquid fuel additives with no mixing, no storage, and no handling of dangerous chemicals
* Allows older ‘leaded-only’ petrol engines to use standard grade unleaded without adjustment or modification of any kind
* Works with petrol & diesel
* Fit once and lasts almost forever
IMPORTANT: The above assumes engines in good condition. Fuel catalyst products will not rectify or compensate for existing engine faults.

The RAF used an early version of the technology in WW2 to enable Hurricane aircraft that needed high-quality fuel to operate on lowquality fuel instead 1960s In the 1960s an ex-RAF engineer named Henry A. Broquet who was living in South Africa at the time drew upon his wartime experiences and invented Carbonflo which was the world’s first commercial product of its kind.

Henry Broquet and his original Carbonflo patent from the 1960s. This is the earliest known reference to the technology in its current from and means Carbonflo is the product from which all commercial fuel catalyst products in Britain or abroad actually originated 1960s

Carbonflo was used in South Africa to cut carbon build-up in marine engines and to reduce emissions produced by underground mining equipment. But it was reportedly then ‘bought out’ by a large company and disappeared from the marketplace.

Twenty years later it was re-launched (this time in Britain) and was again soon reported as beneficial for saving fuel and cutting pollution. Late 1980s & unleaded petrol In the late 1980s unleaded petrol was introduced in Britain to replace leaded Four-Star.

This caused serious problems to millions of British motorists because attempts to use it in ‘leaded-only’ engines frequently resulted in overheating and engine damage.

Thanks to his wartime experiences with the RAF Henry Broquet knew a simple once-only installation of Carbonflo would overcome these issues. Soon the product was in use for unleaded conversion in very large numbers of vehicles including those owned by police forces, ambulance services, local authority fleets and many others.

Beneficiaries included Hampshire Police and the ambulance services of Lancashire, Hampshire, West Midlands, Isle of Wight, Shropshire, East Sussex, Bristol, Mid-Glamorgan, Leicestershire, Salisbury, Ribble Valley and East Dorset Ambulance to name a few. Meanwhile Glasgow City Council equipped its entire 1,000-strong fleet with Carbonflo and there were very large numbers of other users besides.

With utmost consistency engines that otherwise could not have withstood use of unleaded at all were reported as running at least as well and often far better on unleaded with Carbonflo than they had previously on leaded, with better economy more power and reduced emissions. This was a repeat of what had happened with the RAF in World War Two: “high-octane performance from low-octane fuel”.

Carbonflo on BBC TOP GEAR when professional fleet managers who were using the product were interviewed and confirmed the claims made for it Carbonflo was also widely used by commercial haulage fleets and fishing trawlers in heavy diesel applications to save fuel and cut pollution and again clear-cut benefits were consistently reported.

Furthermore it was tested under controlled scientific conditions at Leeds University Department of Fuel & Energy by Reader in Combustion Engineering Professor G. E. Andrews, Bsc, PhD, CEeng, MIMechE, memASME, MSAE for effects on toxic emissions produced by petrol and diesel engines alike and substantial reductions were recorded.

The reduced emissions included Carbon Monoxide and Unburned Hydrocarbons, both of which are by-products of inefficient combustion, together with NOx which is an especially toxic byproduct of high-temperature combustion. Therefore Professor Andrew’s tests were also scientific evidence of better combustion which in addition to reduced pollution is always bound to result in better economy.

Then in 1990 Henry Broquet sold his manufacturing secrets which led to Carbonflo being copied and other products appeared on the market including Powerplus, Comtec, Cleanburn, Greentune, System 4, FuelSaver, FuelStar, UltraBurn, and others.

They used the same technology and unsurprisingly achieved similar results and won large numbers of impressed customers. For example 1,000 vehicles belonging to Thames Water and another 1,000 belonging to Midland Electricity Board were fitted with fuel catalysts, again resulting in “high-octane performance from lowoctane fuel”.

Also like Carbonflo many of the other fuel catalyst products were objectively tested at UK establishments such as City of London and Southampton universities.


By 1990 Carbonflo and derivative products based on the same technology were in use in an estimated 200,000 British vehicles and marine vessels This led to a relentless flow of repeatable and verifiable reports of fuel savings, better performance, lower emissions, ability to use low quality fuel without loss of performance, and more.

Indeed the results were such that that the expectations of ourselves and many others were that they would soon be taken up by the remaining 25,000,000 potential British customers at the time. 2017 As things turned out the universal adoption of the technology in Britain that many had expected did not happen.

Overseas however further products that to all intents and purposes are copies of Carbonflo have continued to be extensively tested by competent bodies such as accredited laboratories, scientists and government agencies. As a result they are now in highly successful use in innumerable instances and prestigious beneficiaries range from shipping companies in the Pacific to mining corporations in Asia to Train operators in India to large scale heating boiler installations in New York to United States armed forces among innumerable others.

All this has resulted in a virtually unlimited database of evidence in support of the technology. Questions? info@carbonflo.com
