yeah, i saw one of those videos where they ran an electrolysis machine, and then compressed the Hydrogen-Oxygen mixture into steel gas bottles, and then fed it into the carburetor of a car. meanwhile i'm thinking "you may use less gasoline, but you still have to pay for the extra electricity". the heat of combustion of the mix is higher than that of gasoline, but how much is that going to cause your electric bill to skyrocket? efficient electrolysis requires a lot of current, and a lot of the power is dissipated as heat in the water, the rest of the energy dissociates the water molecules (and there's heat spent there also). then you compress it, so... more loss of energy through heat. then you feed it into your carburetor, and the dissociated water burns and recombines, and the heat of combustion is significantly less than the heat loss in the dissociation process. to add insult to injury, some of the hydrogen has escaped from the container, and and electrolysis apparatus by diffusion, making the HHO mixture a little bit rich in oxygen (and because some hydrogen has escaped, the chemical energy available in recombination has been diminished.I was looking on duck duck go for some info on nickel catalysts, if you follow the logical line you end up at HHO cells. Especially as hydrogen and CO2 need nickel catalysts to combine, anyway sure enough the HHO stuff popped up, but one of the good guys who debunks this stuff has a video, i couldnt resist posting it as it had me in stitches.
I think he is a aus engineer, but has some good stuff on his vids. Also a little self promotion...... I will be starting a you tube channel.

on older carburetor/point-condenser cars, injecting a small amount of water vapor into the intake manifold will improve gas mileage, but not due to a dissociation/recombination reaction. it actually moderates the burn rate of the fuel/air mixture, which causes vaporization of any aerosol fuel droplets (which don't always burn completely) into fuel vapor which burns more efficiently. since the flame front is slower, the aerosol droplets have time to absorb heat and vaporize while combustion is taking place. however, too much of a good thing can be bad. too much water and the burn rate gets too slow, and there will be unburned fuel in the exhaust. most modern cars can't benefit from water vapor injection because they are already burning fuel efficiently.
i have a book about gas engines from 1912, and one type of automotive carburetor that was in use back then was like a small fractional distillation tower. the fuel would be boiled by heat from the exhaust manifold and the carburetor, acting like a fractioning tower had a condensation chamber at the top where excess fuel vapor would condense out and go back to the boiler section. there was a throttle valve that opened to the intake manifold, and the column of fuel vapor would get sucked out and mixed with air. the text describing the carburetor said it was very fuel efficient because the fuel could burn efficiently at 100:1 mixture (because the surface area was molecular rather than aerosol droplets). the carburetor had it's limitations though, first that it required a regular carburetor to start the engine and get the evaporator up to operating temperature, second, there were circumstances where all of the lightest constituents of the fuel, leaving behind fuel constantly getting heavier and more difficult to boil (i.e. it would boil off mostly pentane and hexane, and leave much of the septane and octane behind). with the mixture not containing the right proportion of heavier alkanes, the engine would produce less power.
Lead free petrol on the whole dosnt have much at all, its got some isomers but not many and not in any large amount. I have a old chemistry text from the 60's when lead was in petrol, all kinds of goodies like benzene etc.i had read in a chemistry book that gasoline was (at least when that book was written) was a mixture of pentane, hexane, septane, and octane. the boiling points of those constituents are within a few degrees of each other. that was written in the late 1930s, and catalytic cracking had been invented by that time, but not used in any large scale refining until WWII. since the gas engine book was couple of decades older than the chemistry book, the mixture then known as "gasoline" was most likely pentane through octane. gasoline still consists of a number of liquids with different boiling points (and flash points).
hmmm... according to this: https://en.wikipedia.org/wiki/Hexane
hexanes are still used in gasoline. maybe you're referring to a particular isomer, or hexane at a very high level of purity?
Like emission targets, inside a lab is nothing like real world driving. I think it would take some doing to replicate real world driving. I wasnt aware of any research using remaps. As i said above if people wan to look into it then remapping goes without saying. BUT whatever you do you cant get more out than in, you can get it from different/cheaper sources but mostly these are alternator connected devices, those are a dead duck as it would break one the laws that there is no if and buts about.There is a serious technical evaluation of HHO addition here, for anyone interested.

In essence it can possibly give some very, very marginal benefits, _if_ the engine management system is fully recalibrated for different timing and mixture requirements..
Without that it's far more likely just to mess things up and decrease performance, if it does anything.
And, you are extremely unlikely to get the all the critical timing and mixture conditions right all the time outside a laboratory.
this also presents problems for fusion energy because all of the electromagnetic energy released (even in the form of gamma and X- radiation) is part of the thermal losses if it can't be captured in some meaningful way. since gamma and X-radiation tends to pass through most substances unimpeded the loss of this energy is non-recoverable. the only fusion reaction that has been proposed that doesn't have large losses of this type is hydrogen+boron->carbon+beta. since the beta particles are electrons, the reaction produces electricity directly.The free lunch rule cannot be violated no matter what you do, energy cannot be made! it can only be transformed. You cant magic something into existence, electrons proton and even the sub atomics have to exist already to form something. Otherwise you could rightly claim yourself as god
This has made me really curious, are you looking at UK petro0l? I ask because nothing on the GC comes back as Hexane or a identifiable isomer. So makes me wonder if its not uk petrol or maybe they are adding an additive that changes it, but chemically that is more wishful thinking than fact....this also presents problems for fusion energy because all of the electromagnetic energy released (even in the form of gamma and X- radiation) is part of the thermal losses if it can't be captured in some meaningful way. since gamma and X-radiation tends to pass through most substances unimpeded the loss of this energy is non-recoverable. the only fusion reaction that has been proposed that doesn't have large losses of this type is hydrogen+boron->carbon+beta. since the beta particles are electrons, the reaction produces electricity directly.
back to hydrocarbon fuels, this data sheet https://www.atsdr.cdc.gov/toxprofiles/tp72-c3.pdf references an Air Force assessment from 1989 that shows hexane as a constituent of gasoline (22.6% by weight adding up the three hexane isomers shown). the fact that there may be a shortage of purified hexane for diagnostic use is not an indicator that it is not in gasoline, but more likely an indicator that obtaining hexane in highly purified form is more difficult than refining gasoline. the type of hexane you are referring to is most likely linear hexane, which is half of the hexane content in gasoline.
while looking all of this data up, i came across a method people are using to clean carbon buildup out of their engines, and in some cases improve their fuel mileage, and that's the addition of small amounts of automatic transmission fluid to the fuel. i know from experience (due to a faulty modulator valve diaphragm) that large amounts of transmission fluid in the fuel produces huge amounts of water vapor (white smoke). it did improve the gas mileage of that car until i replaced the valve diaphragm (but at the cost of 2 quarts of ATF per tank of gas that was getting sucked into the carb, didn't save me any money).
But then again you also get ever clear ethanol where as we dont get anything near that purity without a license (exemption) and for alot more money.
Good one, UJ... your government doesn't want people tinkering with anything more dangerous than bubble wrap. ...
They are just tax grabbing!they sell it in liquor stores.... depends on what state, though. i grew up in Massachusetts, and they don't sell it there, but they sell it here in Colorado. from what it sounds like, your government doesn't want people tinkering with anything more dangerous than bubble wrap. that's not to say we don't have politicians here that have the same silly ideas, but we do have enough level-headed politicians to keep most of the silly ones from getting their way.
Thats his town car, saves on parkingGood one, UJ...
(BTW, love your avatar. Were you Tank Corps?)
i wish i had one, it would be great in traffic too...Thats his town car, saves on parking
That works in my book... team chief made me an honorary tanker ...
That massey fergy we got drinks fuel like a sailor on leave for the first time. one of the newest tractors we have ever owned and by far one the worse for fuel economy, what really stings is the fairly small tank on it.
They are just tax grabbing!
