Re:Ethanol Facts, Car Mods - 2008/05/07 06:36 my bad... I don't generally consider a spark a plasma since it is so small... however you are correct in saying that an arc is plasma... since a spark is overcoming the dielectric properties of air through ionization, allowing massive current to be drained very quickly. Check them out... what I meant by plasma... was a plasma "cloud"... something more like you would see in a florescent light.

they are called "pulstar pulse plugs". I was looking at them... they claimed to be built off of a capacitor, but what I was thinking, is the charging of that capacitor. To get any gain of power, I would think that you would have to saturate the capacitor and I'm not sure how you could saturate the capacitor with just 1 spark. I had originally thought the plugs were based around a LC circuit, allowing a multiple spark discharge, in a fraction of a second.

I was wanting to do testing on them to see if they really do have an increase in output "power" or if their claim has no proof, but I have better things to do... lol

Re:Ethanol Facts, Car Mods - 2008/06/11 05:59 I know it may be kicking a dead horse, but E85 is now becoming a bit more common in our area. So dad is wanting to convert our muscle car to run it. I have read several different things about E85 including that it eats rubber... SO... the question is, what is required to convert a carburated car to E85?

- Rejet carb (take current jet size, and multiply it by 1.4)
- Change Float depth(carb adjustment, fuel into float bowls)
- Eliminate rubber in fuel system (is this just myth... or is it needed)
- Eliminate non coated steel in fuel system (corrosion with E85?)
- Eliminate cork from carb (supposedly dried out by E85)
- Advance engine timing(to prevent spark knock)

Anyone know any other possible problems/challenges with Ethanol blended fuels? Or possibly at what percent gas/ethanol will actually damage rubber lines and unplated parts?

Re:Ethanol Facts, Car Mods - 2008/06/11 09:15 E85 is total shit.

It burns at a lower temperature, doesn't give off as much power (no more muscle in that car), and it really isn't cheaper. The price difference you see is the subsidization that you are paying the difference in in state taxes. The tax offsets the visible cost of the ethanol.

So...

DON'T DO IT!

See mpgresearch.com, as there are tuners on there who get in excess of 80mpg on some cars, some more, some less.

Re:Ethanol Facts, Car Mods - 2008/06/11 18:31 it also takes more energy to make so in the end its worse for the environment.

Re:Ethanol Facts, Car Mods - 2008/07/01 07:03 at this point... not worried about the environment... worried bout my pocket.

as for power. yes, ethanol does have less power per unit density than gasoline... but it is VERY good to run in high compression motors (race engines, etc). and seeing that our engine is at least 11.5-12.5: 1 ... then chances are it would run well(and efficiently). Not to mention, the ignition system in our car is multiple spark discharge, which means, depending on the advance of the distributor, the engine will not spark 1 time to each plug, but multiple times to that same plug in a fraction of a second.

as for mileage... I have looked into the "hydrogen-oxygen generators"... but I'm not sure how well it would work. On a fuel injected vehicle... it would really confuse it. Not to mention, when performing electrolysis... on stainless steel... it does not appear to be doing anything to the metal... but it is actually stripping the chromium from the steel. I would however like to build a PWM circuit up to experiment with that since a standard dc current does not seem to produce too quickly. I was reading tho, that the frequency and duty cycle must be adjustable(not sure how they are doing that... for frequency a 555 timer requires a capacitor to set it).

*smiles* as for a credit from the gov't... well, we don't have income tax, we have one of the lowest taxes on fuel, our "wheel tax" is $60, and all we really have is sales tax that hasn't gone up in at around 12 years.

but yeah... the goal... is to not have to pay $9.00 a gallon for a 110 octane fuel... when ethanol is approximately 103, and cheaper than gas!
