Welcome to the Broquet fuel treatment catalyst, a unique and exciting product that significantly improves the combustion of hydrocarbon fuels.


There have always been many products on the market which claim economy and/or exhaust emission improvements; some now even look similar to Broquet. However as you will see from the 'Broquet History', this product is genuine and was first developed in 1941 by a young RAF engineer by the name of Henry Broquet. Like many other important products developed during wartime, it was developed as a matter of urgency - and in the case of Broquet, it was to cure fuel quality related problems with aircraft engines.


After the war, Henry went on with the development of the product and eventually returned to the UK in 1986 to start manufacture.  Following his death in 1989, the Company was re-named Broquet International Ltd. to honour Henry's work in developing the first fuel treatment catalyst. The Company remains privately owned and continues to manufacture and market only this one product - the Broquet fuel treatment catalyst.


Briefly, Broquet is a catalyst in pellet form that when fitted into the fuel tank or fuel line of a diesel, petrol or oil fuelled engine, reacts with the fuel to improve the efficiency of the combustion process.  It will treat the fuel for 250,000 miles or 400,000 kms. (6500 operating hours for marine and off-road applications) and

works not only by promoting more efficient combustion but also removing, and then inhibiting the build-up of carbon deposits, waxes and gums that normally form in the combustion chamber.  The overall result is significant reductions in exhaust emissions and fuel consumption, more power and less maintenance due to cleaner combustion components and lubrication oil.


Whilst modern automobile engines are manufactured to a very high standard, no engine can perform to its design criteria without consistent high fuel quality. Unfortunately, refined fuel degrades over time and particularly during the transportation and storage stages.  This is another area where the use of the Broquet fuel treatment catalyst has proven to be particularly advantageous iby limiting this degradation of fuel.


For parts of the world where leaded fuel is still available, and for Classic Car owners everywhere, Broquet has proved to be very successful in 'converting' leaded petrol-only engines to run safely and efficiently on unleaded petrol, even during gruelling long-distant rallies


Broquet's ability to improve the efficiency of the fuel combustion process is fundamental to providing its many benefits. These benefits have already made Broquet very successful in the worldwide retrofit market, but with increasing demands on manufacturers to produce vehicles, boats or off-road vehicles with low emissions and that perform well regardless of local fuel quality, Broquet is becoming increasingly important to manufacturers.
