Fuel conditioning by magnets

How can this work?

Magnetic water softeners do work (by making the minerals not stick to things) but that's a different thing...

I don't know if this relevant but I once tried an experiment using a petrol blow-lamp and a strong magnet. There was no difference to the flame whether or not the magnet was placed anywhere on the blow-lamp or not... Not very scientific, but it convinced me that the claims for these magnetic devices was not proven.

Whuh...

Sounds like the same school of idiot science that produces people who sell (and buy FGS!!) magnetic copper bracelets to ward off arthritis!!:

Its an utter load of pish.

Final year students up and down the land have been trying for years in thermo labs to prove they work. One student even strapped a super cooled MRI type magnet round the fuel pipe and it did bugger all.

As one Prof put it at a post conference bar session "there is more chance it will improve your fertility strapping them to your nuts than improving fuel economy"

Magnets

I was told they may possibly work while the liquid is circulating,but the second it stops,the minerals or whatever settle out again.
Acid water is soft,maybe nitrous oxide injection could work?
If the magnets work against arthritis,why don't hospitals place patients in an MRI scanner for a couple of minutes?

"Fuel Magnets"

I have run big Yachts for years and over the past three years have used a unit which is sold as 'Algae-X' and is installed in-line before the primary Racor.It is supposed to improve diesel fuel by removing the algae which is in all diesel (at least where we operate).I has to be cleaned sometimes,and it seems to work,witness less filter changing etc.The unit has magnets inside----which do what......?Anyone know how this works?

"Fuel Magnets"

Seeems to be advertised for Diesel use,mainly Marine,Heavy Equipment,etc.Cars have small storage tanks and a fast fuel turnover and therefore don`t grow stuff in their fuel tanks.We carry 800 gallons and only refuel once every 4 months or so and some water always enters the tanks either from condensation or water leaks from the filler or from some idiot using the wrong filler.This feeds the algae with moisture and it grows into a brown mass that blocks everything and causes all kinds of trouble like going onto reefs without an engine in a blow.it seems to be worthwhile to fit one,under the circumstances----and if you own the Yacht....

Probably in the same way magnetic "filters" work in ponds. The idea is that they alter the water's chemistry which prevents the algae growing. The algae "live" in the interface between fuel and water that almost always exists in the bottom of tanks.

Personally I think all these gimmicks are similiar to snake oil.

They may have some marginal benefit but I am dubious the claims made would stand up to proper scientific scrutiny.

"Fuel Magnets"

OK,thanks.Appear to work for us and they are not expensive-----anything to improve the abysmal fuel in the BVI``s
Cheers for replying,anyhow.

Its more likely that what its doing is pulling the rust particles which the algae have clumped around into it. You have similar setups in central heating systems to pull ferris out off your system so it doesn't clog your boiler up and knacker the pump.

Magnets definitely work well on preventing minerals in water sticking to pipes etc. I have used them in several houses. And if you install one in an old house , for the next few months you have chunks of scale clogging up your shower etc as they come off the pipework! I have no problem believing this, therefore.

But using a magnet to make fuel burn better seems to be utter nonsense. If there was any measurable improvement, it would have been verified by now, because it would be so easy to measure.

Are you really really sure?

Because there are real scientists using the real scientific method who were unable to reproduce even the smallest effect.

That happens even if you don't install magnets

Hello!

Because there are real scientists using the real scientific method who were unable to reproduce even the smallest effect.
There is at least _some_ scientifically gathered evidence that magnetic fields can alter the crystallisation of calcium carbonate. Whether this leads to less calcium deposits in water pipes has yet to be proven, though. When we moved house last time (10 years ago) I thoroughly researched the subject (with the aid of a physicist) and came to the conclusion _not_ to spend any money on magnetic water treatment.

Regarding magnetic fuel treatment, there exists zero scientific evidence and zero scientific explanation of the effects claimed.

Here is some reading stuff for those interested in the subject:
Quick overview: CSI | Magnetic Water and Fuel Treatment: Myth, Magic, or Mainstream Science?

In depth literature research with many links: Magnetic water treatment pseudoscience

Regards,
Max

The link in the original post claims:
...fuel conditioned by a strong magnetic force carries more energy and mixes more readily with air...
Sadly, it doesn't tell us where this "more energy" comes from.

That is one excuse why it works

Another is that it aligns all the molecules so decreases friction in the pipes.

Then another theory is that it does something to the free radicals.

As you might have guess I did have something to do with thermo lads and the testing of said magnets.

When the students orginally did it and failed to produce results it was because they wern't using a rare earth magnet. As the Prof said its bloody rare alright because one doesn't excist. They then just to humour them used a production magnet out of the box. Then the fuel line was to big, the fuel flow was to high. Magnet to far away from the injectors I think you can see my drift.

In the end we borrowed a super cooled super magnet which was a beast of a thing require a heap of work to get it safe due to the fact you are sticking a magnet next to a ferris box of metal and was that powerfull it could pull screws out of blockboard just by turning it on.

The students used it on petrol, desiel, and turbine test beds with no difference recorded. The reply was that we were using the wrong type of magnetic fields???? The chaps flogging this stuff need a Noble prize cause they know about stuff that nobody else does.

I am actually suprised none of importers have turned up on this thread. 10 years ago they used to regularly join BB's when the subject came up to confuse matters when it was being discussed. We had the amusing situation that they didn't know we were all scuba divers and on the diving BB's discussing its application on boat engines. So they were arguing with the same people in 4 different places and using circular referencing to try and prove a point.

I work for one of the largest analytical instrumentation companies who amongst other things, make instruments to test fuels. We certainly couldn't find any difference, and as a colleague said -
"it's a product that looks better in Powerpoint than Excel".
