it always pays to open your ears before pulling out the ruler to see who has the biggest! LOL
But it was a good read though!

They dont claim to be able to run a air to fuel ratio of 40:1, the only 40 odd they talk about is the 44 to 50% increase of fuel economy. Quote: It allows you to take an internal combustion engine from the standard 14.7:1 air-to-fuel ratio to an incredibly lean 24:1. At this ratio Lol, I admit, I didn't bother reading it as I've read it before. I was just going off 40:1 steady mentioned. In any case though, it may as well be 40:1, same diff. Lol at 44-50% increase in fuel economy. EDIT: I thought I'd mention. I'm fairly sure it used to say 40:1 back when phong posted this. I am also certain there was a 40:1 AFR when i posted, that's why i went with it...i tried tracing the old website but i just got lazy. buh. phong =P~

seems to have stirred up a bit of a debate, yeah you guys are right with the 14.7:1 ratio, that is to burn 1 part of fuel you need the correct amount of oxygen for complete combustion. However where they claim for higher ratio's you will also run into problems with the formation on nitric oxides which are something you kinda want to avoid cos afterall we use air not 100% oxygen and air is ~80% nitrogen (bad for the environment etc etc makes acid rain)
The stoichiometric ratio of 14.7 depends on the fuel type, and the amount of impurities which for a theoretical value you would ignore. The beauty of tuning your car allows you to tune to your specifications, max power, max efficiency etc etc. As for plasma plugs, i'd have to see it to believe it, as i am a bit sceptical, I don't see how changing a plug can change the amount of fuel you use, compared to complete efficient combustion. Also would be interesting to see (havent read the article) how much power/current they draw? |

If he was going to run a 40:1 ratio he'd have to reprogram or chip or get a motec or something cause the stock ecu wouldn't go anywhere near that lean.
these plugs WILL! improve economy. but not to 40% maybe 5% if your lucky cause they will ignite ALL the fuel the spark touches. you can see heaps more in the wiz bang one than the old school one. it would just get a cleaner bang. and it will really improve cold start economy! heaps. a form of these have been used in top fuelers for years. they'd be good for my kart racing, but after 5 mins id be looking for a new motor. it'd arc weld the head, barrel and piston to buggery thats just my two cents

I'll admit that i'm no expert here but unless you remap the computer w'ont the oxygen sensor feedback adjust the mixture strength to the stoichiometric point (14.7:1)?
I think I'll just stick with normal srark plugs for the moment LOL.

Ofcourse you'll have to change computer settings!

well obviously youd tune it for the right AFR.

I was referring to the AFR of 40.7:1 everyone was taking about. you'll probably have holes on the piston the same size as the cylinder bores. lol

We got another guy who doesnt know what he's talking 'bout. ok smart a**, what specifically dont you agree with in my post.... and before you reply, ill state that by LEAN mixture, i am talking about a mixture leaner than stoich... efmarek wrote: U dont know what your talking bout! U dont need a flame front. The plasma fills the whole combustion chamber instantaniously.......which means it ignites the whole volume of fuel AT THE SAME TIME. Which obviously means there is no chance for PRE-IGNITION.The beauty of it is that u can use s**t fuel for a hi-po engine.
and this?? from a man who seems to be above all in the knowledge stakes... it makes me laugh to think that you would like to ignite ALL of the volume of fuel AT THE SAME TIME... imagine how a cylinder pressure graph would look if you were to infact achieve that?? conrods wouldnt be particularly happy also, do you know what pre-ignition is?? if so, would you be willing to enlighten me on how igniting all of the fuel at the same time would mean there is no chance for pre-ignition... im struggling to find the relationship between the two.. looking forward to an indepth, informative reply from you..

If your so expert on this topic, why cant you make up your mind?

Dug urself a bit of a hole mate??????? so now there IS a corect afr???? would it be 14.7:1 do you think?????

Nice one again!!
You've taken my comments out of context.
