I've heard this in the past, a small amount of tin helped with the poor quality fuel during the war. Modern engines designed to run on lead free with all its additives are possibly not going to benefitThere 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 'Broquet Story', the product 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.
Yep and as I said so do a lot of other peopleAfter 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.
Ok so in theory it provides a cleaner burn which will help in less build-up of crud, not sure about the removing bit, crud that is already there is surely just going to get baked on with heat and pressure. I remember decoking cylinder heads in the past, always had to scrape them clean.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
