Broquet International Limited have been manufacturing and marketing the fuel treatment catalyst in a great number of countries and for a wide variety of applications, for over 25 years. In this time we have been asked some basic questions about the product and how it works. Therefore in order to help our customers, we have shown them below, together with our answers.

WHAT EXACTLY IS BROQUET? - Broquet is a fuel catalyst, manufactured in pellet form with each pellet being a combination of different metals bonded together in a unique process. This catalyst is particularly effective when in close proximity with mild steel and therefore the pellets are either enclosed in a simple mesh for inserting into the fuel tank, or contained within a steel container for fitting directly into the fuel delivery line.


WHAT IS A CATALYST? - A catalyst is something that changes the rate of a chemical reaction, whilst itself remaining unchanged.


HOW DOES IT WORK? - It is known that the catalyst when in direct contact with a hydro-carbon based fuel, in a liquified state, improves the combustion efficiency of that fuel. The exact mechanisms for this are still subject to on-going research which is not unusual in the field of catalysis.


HOW LONG WILL IT LAST? - Theoretically a catalyst will last indefinitely, however the contaminates that are ever-present in fuel will eventually adhere to the surface of the pellets. This process is however very slow, and a miniimum active life of 250,000 miles/400,000kms can be expected for smaller vehicles, 150,000 miles/240,000kms for trucks and buses, and 6,500 operating hours for off-road and marine applications.


WHAT ARE THE BENEFITS? - Because the fuel catalyst improves combustion efficiency the benefits will be 


1) Gains in Road-wheel Power, or improved fuel economy (depending upon how the vehicle is driven)

2) Reduced exhaust emissions, particularly HC and CO

3) Cleaner combustion zones and components (spark plugs/injectors, piston rings and crowns) 

4) Stabilisation of fuel (inhibits the deterioration of fuel quality)


HOW QUICKLY DOES IT TAKE EFFECT? - Broquet will start to work almost immediately and the customer will first notice that the engine is smoother and more responsive. However the improvement is progressive due to Broquet's cleaning effect, and therefore depending upon the condition of the engine and how it is driven, may take up to 5,000 miles for the full benefits to be realised.


CAN IT BE TRANSFERRED BETWEEN VEHICLES? - In-line units can easily be moved between vehicles. However the In-tank unit should be considered as a one-vehicle treatment system, as once it is in the fuel tank it is not designed to be removed and therefore this can be difficult, and should be undertaken only by a qualified motor engineer.


WILL IT WORK WITH A CATALYTIC CONVERTER OR PARTICULATE FILTER? - These components are both positioned in the exhaust system to treat the exhaust gases from the engine, whereas Broquet is fitted into the fuel delivery system to an engine. By improving combustion efficiency and reducing the exhaust gases, Broquet will reduce the amount of work required of these expensive components, thereby extending their working life.


CAN BROQUET HELP WITH ANNUAL VEHICLE EMISSION TESTS? - Broquet has proven to reduce the two main gases tested for in the annual emission tests, total hydrocarbons (THC) and carbon monoxide (CO) by approximately 20%. This can make the difference between a 'Pass' or a 'Fail' at the annual emission test, or a roadside check.


WILL BROQUET WORK WITH DIESEL FUEL? - Broquet will work with any hydrocarbon-based fuel which is in the liquified state.This means that any vehicle fuelled by petrol, diesel or oil will benefit from having Broquet fitted.


HOW DO I KNOW WHETHER TO FIT AN IN-TANK OR IN-LINE UNIT? - Either type of unit can be used for any application. However based solely upon cost, the In-tank method is generally recommended for smaller engines (motorcycles, cars and pick-ups) and the In-line units for larger engines (trucks, boats and generators.


HOW IS IT FITTED? - All units come with general fitting instructions, but as fitting required working on a fuel system, it is strongly recommended that only qualified motor engineers carry out the fitting of the units.


HOW MUCH WILL I SAVE? - Fuel saving will vary according to condition of the engine and how it is driven or operated. However typically savings should be in the range of 7% to 12%.


WHY DON'T VEHICLE MANUFACTURERS RECOMMEND IT? - Fuel is purchased by the customer, who also pay for servicing and maintenance of the vehicle. As the use of Broquet results in increasing the life of an engine and components, there is no benefit to the manufacturers of fittting Broquet only an additional cost. 


WHY DON'T THE OIL COMPANIES RECOMMEND IT? - The business of oil companies is to sell oil. As Broquet reduces fuel consumption there is no commercial advantage to them in supporting Broquet.


WHERE DID BROQUET COME FROM? - The Broquet product is named after Henry Broquet, the person credited with the initial development of the fuel catalyst. More information can be found under 'HISTORY'.
