Thanks Magnum for the replay.Is the idle speed motor located in the throttle body?Are there any mechanical adjustments that can be done to the valve?

It's in the throttle body. It's job is to modulate air by bypassing the throttle blade.

All the adjustments are electronically set.

Acetone rules!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
or Xylene
surprised my dad too put a quart to 10 gals in his 89 318 lebaron and he asked my what did i do tune it up or something its smoother more responsive and his trips to the beer distributor only take one tank of gas every 3 weeks instead of 2 weeks. I showed him and he calculated the btu content and said why didnt i think of that. hes a retired aerospace engineer.

New year so lets hear the Acetone tests that are still running Im looking at 17 mpg up from 15 mpg with 20% mix with 89 octane while beating the C... out of the car every day I think thats great. been running test for over 100 consectuive tests. (Stasticial signifient result)
88 Lincoln town 302 THB injection, cats empty dual ex. no mufflers.

Sounds like you're losing money.

I am glad I don’t work with some of these so called gas experts

With all the so called milage addedrs that are claimed - if a person would use them all we would be pumping the socalled depleted oil stocks back into the ground for recycling.
If acetone were the real cat's meow with the so called (oil company self imposed shortage) don't you think that they would add this to the fuel before it is distributed. Much like ethonal blends. Which do nothing for milage (cut it back in some instances even on multiuel rated vehicles and cut power output). Hopefully the corn farmers will reap something from it.

I think a lot of the benefit people are seeing are from the cleansing propertiers of the acetone in their fuel systems. Note people who put acetone in barely maintained cars are reporting the best results. It may be just cleaning up the fuel system. The other benefit is the additional octane/cooling effect from evaporation.

I wonder what the emissions would look like with a 10% mix??

Emissions are way down with my 20% mix.
remember my NY Gas already has 10% methanol wich hurts performance as is but helps emissions from 100% gas.
and My engine is Highly matained as far as clean fuel sustem and so on - do you pull all your fuel sustem parts and flow test them with calibrated flow meter? and your injectors and test flow @ pressures with a pulse generator, and test spark system for actual voltage and current at the plug gap in Jules of energy???? Ha HA.
just cause I beat the C --- out of it doesent mean I dont follow scientific method accepted by ASTM and way more strignent test case control that you may think..
I do high purity chemical engineering for 20 years and am not your usual joe Mechanic .
I A MAD Scientist and Mopar ADDICT by nature and profession.
you nay sayers can say all ya want while I and some other believers bring the future to fruituition in fuel improvement and keep performance as a priority unlike gas companys which want to sell more gas not less.
either get on board cause the train has left the station. (playing) Ozzies "Crazy Train"

on My 2.2 which is Carb/MSD/dash timing control at 36 deg adv total and intake vac @15 1000rpm my Hc dropped by 110 ppm and my Nitrogens by 1/2

in my 302 EFI there was better decrease cause the computer reset mixture as per O2 sensor out put
and the HC were 300 ppm less and N2s were still about 1/2 without Ace tone as with Gasoline
the results vary on actual ppm as the static air press goes from high 29s to 30"s as the denser air days heve closet to the 21% o2 as I live at 3 ft above sea level on Long island and unless its a storm im never below 20% o2 as per my Nyosh Gas air monitor shows. and its caled. to 1%,10%,20%,100% using lab bottles of air products calibration gas.

I run the system empty put in 5 gallons of Gas which is already 10% methanol by NY code 89 octane Sunoco. same station 5 years get gas every 2 days .
add 1 gallon Acetone leaving house drive 2 blocks then put the gas in. need to do that to run the car from empty.
its industrial acetone (like Fisher reagent)
so im a little above 20% but I usually pound it for 2 blocks on 100% acetone and figure as a minimum 20%

been doing this for at least 4 months before that i did it with Xylene and tolulene but that stuff gets expensive. even though cost was not a determing factor the xylene was less controlled as i did not totally empty system each time and filled 5 gals and for approx a quart each time anythindg over a quart of Xylene gave much better top end and highway acceleration but was rough on idle caues the o2 sensor got confused on the mixture as the out put voltage looked very noist (500mv ac backround at idle vs 80 mv noise on gas or acetone or Meth.)
I pulled my injectors 4 times and fuel pump and flow tested it on a bench with 3 different viscositiy fluids alch, gasoline,kerosene thru 2 differnt flow meters, ultrasonic mass flow meter(Brooks) and analog ball float in series both open head flow and restricted to heas press of 5 back psi which is typical head at 1k rpm and 35 % opening or duty cycle on the injectors which I control with a squear wave of 12 volts loaded sidnal. the car gives a modified wave not as clean as the bench but within 5% total open area when plotted on a scope (my fav for road test if Fluke Scope meter) my bench is a Techteronix 4 trace circa 1988 (calibrated to National stds every year) Im also the Metrology engineer for last 15 yease here at work.

I summerize by saying the Acetone enhances the mixing of gas and air (inter diffusion) or oxidation enhancement cause it allows more free O2 TO BOND onto the Hydrocarbon chain. Octane is rather stable and needs help to bump open a spot surrounding the carbons and the Carbon in the Acetone grts right in there.
I have run O2 in PPM and PPB test on my Leco 410 oxygen determinator which you must be familiar with and it show more 32 ppm average Free O2 with acetone /gas in every 1 cc carbon crucible tested . so this transfers to more o2 per CC that the particular car has delivered to the cy;l. and the EFI does it better as real time mixture enrichment then the carb (unless i open up my jets)
No I didnt writd it all in a registered lab notebook and patent it cause it for fun and Moparts info. I have patents for oxygen induced into many materials to achieve different results, thetmal activity,electrical,chemical, and mechnical propeties such a strain and denuded zones in thermal anneals. published The Marerial Research scociety as break thru technolgy and seinor engineer for worlds largest discrete Semiconductor Company.
lets have fun with this not dissention.
you do a HC test and N2 and get back to me.
ps ive got my own sun and also Heathkit emissions analyzers to test at home before they hit the state cert. dyno.
but I pre fer the long term actual road usage test to provr it where the rubber meets the road or where the rubber goes up in smoke.
ps how bot you send me a gal of real Tetraethyl lead. Im Hazamt lavel A set.

I forgot to add, for the non scientific method ,I have been using Methanol and Acetone for a good 10 years in all my cars to get thry NY inspection and in every instance it improved my performance and lowered my emissions to a passable value what ever that was , since 10 year old cars still got to pass and just leaning it out didnt kill the nox. only lowered the HCs.
thats 12 cars X 10 inspections minimum.
I started trying lacquer thinner early 80s but that was wayyy worse HCs and black smoke.
ant that was even with 10 cfm of pure O2 into intake vacuum fitting. geeze what was i thinking then all were well maintained .
even the lawnmower,

Greg,
Thanks. 110 ppm reduction from what originally?

Funny, some of the stuff (registered lab notebooks, etc), I still use.

While I too do not want to argue, an not having the kinetic chemistry background, could you clarify how acetone allows O2 to bond to a stable chain? Doesn't the heat of compression/combustion first have to start to break downthe octane molecule to expose free radicals? Does acetone breakdown easier allowing faster propagation of this reaction? I can see how diluting octane with acetone can increase the rate of combustion by putting easily breakable chains amongst the harder ones, but that is providing the fact the acetone is easier to combust, right?


And, we buy our specialty fuels pre-blended, I could probably get my hands on lead, but it easier to get toluene....

HCs generally 500s ppm.
the Gasoline and methane mix are less stable than the gasoline alone. as the mixture evaps into a "vacuum" of whatever level it begins to expand the mollecular chain leaving more actual space between the bonded surrounding carbons.as does happen a molecular sieve vacuum generator which tears apart atoms by heat and enpansion then cooling and heavy molecules drop out into the diffusion oil boiling below.
like decrease air pressure allows water to boil or channge state and asorb energy to do so and vise versa a pressure cooker is higher press and requires more input energy (>212) to boil and push the atoms apart.


see any good or industrial evaporator or sputtering or implanter or particle accelerator.
(as in atom smasher) these "spaces" get larger and the coheasive effect between the 8 outer electrons is weaker and vulnerable to attack from a "friendly lookind free electron or carbon looking to ozidize as every thing on the perodic table likes O2 to stabilize (well most cept for inerts at netural state)then it totally breaks open in the combustion compression. thats why aediabatic heat of compression can ignignt low octane gas cause its broken open and most vulnerable to the rapid combination of the entered oxygen with little energy as it looking to satisfy its "dangling bonds" of Hs and Cs with O2 produccing HC+NOX (Nitrogen from atmosphere 80%+ 1 oxygen )
kinda like we ram electrons into Lead to increase outer shell by to and its now Gold in an implanter with high voltade, huge magetic field to steer it and ultra high vac in a few Millitorr. to keep unwanted molecules out of the way.
as I type im running 10 Pure Hydrogen reactors to create different elemential propeties of basic chemicals O2,Ar,H2,N2,HCL,HF,KOH,HN03,and all kinds of metal dopants too.

isn't that similar to Lucas fuel treatment?

probably its no magic just basic chemestry and can be achieved with most hydro carbon solvents.
I sold my Mass Spectrometer for A hemi, wish I still had it now you guys got me going again.

HCs were avg 700 ppm no acetone (Ford 302 EFI)
Hc with 20% Acetone 500 ppm on rolling dyno 1000rpm loaded engine 65degrees and 29.9"Mb atmos.

How do you figure i explained right down to atomic level how the reaction occurs even down to the electrons in the HCs outer shell, so hows that going around the subject you cant get much more into detail than that???
if you can please explain.
no dancing allowed.

same as surfactant (soaps)breaks surface tension to make water molecules open to grabbing grease and dirt ,the Acetone opened the HC chain to allow it to grab more O2 as it evaporates increasing the mixtures oxidation reaction (burinin BTU).
thats another way of putting it.
or do you need the charge of each valance electron on the chain and its energy level at given pressures and temps. if so just look at your periodic table of elements. hint, H is first one top left
