What exactly is Broquet?
The catalyst itself is a tin alloy compound manufactured as a number of
"pellets" (each about 22 mm in diameter). The catalyst is only effective in the
presence of mild steel and the pellets are either wrapped in a mesh for
insertion directly into a fuel tank or contained in a steel cartridge which is
fitted directly into an engine fuel line. It is generally more cost-effective
to purchase the "in-tank" version for cars and smaller engines.
What does it do?
The catalyst institutes a change to the fuel itself, petrol or diesel, which
leads to a much more efficient combustion process. It is this improved
combustion that provides the key to many of the benefits of the catalyst. As a
catalyst, in a chemical sense, it does not itself measurably change but
enhances other chemical processes. In fact the use of tin, as a catalytic
reagent, is well documented.
How does it work?
Scientists do not fully understand the exact catalytic mechanism that takes
place (this is not as surprising as it may seem as there are many catalytic
processes that are not fully understood). Accepting however that such a
mechanism does take place and quoting from a scientific source the most likely
effect of Broquet is as follows:-
"Basically, the product of the reaction (as a catalyst for chemical reactions)
is a molecular species which has more favourable combustion characteristics
than its precursors. The molecular structure has probably been altered in such
a way as to permit the sequential oxidative reaction steps, which comprise
combustion reactions, to proceed in a more smooth and rapid manner. This, in
turn leads to more complete oxidation of the fuel. Hence, better mpg values,
and lower emissions in exhaust gases.
The fact that the chemical oxidation process has been made more smooth and
complete means the chemical potential energy available in the fuel is better
utilised. If the combustion (or "explosion"; as the process is a very rapid
one) occurs more smoothly/evenly, the efficiency of the energy transfer to the
piston will be increased. This will lead to smoother engine running. Another
result will be cooler running of the engine, because less energy is wasted as
heat due to inefficient energy transfer within the system."
How can it reduce exhaust emissions?
The two gases tested at the MOT (for petrol engines) are CO (carbon monoxide)
and THC (total hydrocarbons, in essence unburnt fuel). Each are products of
incomplete combustion and a more efficient combustion process will reduce both
CO and THC emissions. Since Broquet improves the combustion process these
emissions will be greatly reduced. Reductions brought about by Broquet are
substantial and we have many letters from customers saying how surprised their
testing station has been when the car exhaust emissions have been analysed
during tuning or at the annual MOT.
What about use of unleaded petrol?
Many older petrol engines require the lead added to petrol to protect valves
and especially valve seats. Prolonged use of unleaded would be likely to lead
to valve seat recession as the seat material is not suitable for the higher
combustion temperatures associated with use of unleaded. Fuel treated with
Broquet burns more efficiently and the overheating that could lead to these
problems simply does not occur. "Leaded-only" engines using unleaded courtesy
of Broquet have now completed well over 200 million miles collectively without
problems.
Will I need to retard the engine if I use unleaded?
The great majority of engines designed to run on 4-Star leaded can switch to
the lower octane unleaded without the need for "detuning". This is because the
improved combustion process effectively allows the engine to run as well, or
even better, despite the use of a lower octane fuel. Similarly engines that
would normally require the compression to be reduced (many Volvos, for example)
can switch to unleaded after Broquet is fitted without expensive engine
adjustments. Occasionally we have reports of some minor pinking after Broquet
is fitted but this can be overcome by a minor timing adjustment of usually 1-2
degrees which will not result in loss of performance.
Will it be suitable for my car?
Yes! In the sense Broquet is not engine specific as it is the fuel combustion
characteristics that are being improved which must be beneficial for any engine.
How is it fitted?
The in-tank unit is a solid object 5 inches long and 1 inch in diameter which
needs to rest freely in the bottom of the fuel tank. Very often it will slide
down the filler pipe but it is not flexible and will not go around any severe
bends and it won't go through an anti-siphon device. It will not go down the
narrow gauge (unleaded only) filler pipe in cars fitted with catalytic
converters. The alternatives are to remove the gaiter that often joins the
bottom of the filler to the tank itself or to remove the fuel gauge (sender
unit) and place the unit directly into the tank.
How long does it last?
As the unit acts as a catalyst it is not really changing in itself - it does
not slowly dissolve, for example, and will be effective for at least 250,000
miles. In effect a "one-off" treatment which will more than outlast the life of
the engine.
How much will I save?
In a typical situation for a "leaded-only" engine switching to unleaded and
gaining a modest economy improvement after fitting Broquet we would expect
savings to be in the region of 40 p per gallon (more if the user changes from a
top grade 4-Star to supermarket unleaded). For the 30 mpg engine this means a
saving of £133 per 10,000 miles just in fuel cost terms. For a car already
running on unleaded or diesel, savings will accrue because of better fuel
economy and, of course, the lower emissions resulting from use of Broquet could
mean the difference between a pass or an expensive failure at MOT time.
What is your guarantee ?
We offer a money-back-if-not-satisfied promise plus an underwritten Warranty
that states in plain English that if your engine is damaged as a result of
using the product then we will make good such damage at our expense. This is in
addition to your Statutory Rights. Probably your best reassurance is the fact
that we have been supplying Broquet for a decade to thousands of motorists.
Engines have not been damaged (we have several 100,000 miles plus leaded
engines running on unleaded) and in reality run so much better, and last
longer, with the catalyst installed. Broquet has stood the test of time - on
the road, where it counts.
