Aside from any experiments on Mythbusters, unless you're trying to hot-rod your car why would you want to trick the complicated engine management system that's already trying to give you the best mileage it can?
I'm not a mechanic, so I have a question for you all: What's the result of running your engine too lean for an extended period? I don't think the answer will be very positive.
I just looked it up. There's one oxygen in acetone, but it's in the minority and I don't know if it's released.
Now find me a molecule that has a lot of oxygen bound up in it that gets released as O2 under compression, and you have an additive I'd go for (turbocharging without the turbocharger).
hot>pre-ignition>NOX>head gaskets>cracked heads>holes burned in pistons>where’s my warranty?, LOL
You just may get a chance to do that. Mercedes Benz has a diesel with some type of urea injection to keep the exhaust clean.
When the urea runs low, pull over and pee into the tank. :^)
On a serious note concerning acetone.
I believe engines today are running fairly high compression ratios compared to the common octane gasolines, 87-93.
They control pre-ignition with fuel mixture, ignition advance control.
Seems to me that fooling the 'black box' into leaning out the mixture might lead to spark knock and a destroyed engine.
Just a thought.
This reminds me of Slick 50's test claims. Briggs & Stratton later pulled two identical engines off the assembly line and tested them, one with and one without Slick 50. The Slick 50 engine was a lot worse off in the end.
Melted pistons. Think of a NOX setup where the gas solenoid doesn't work and you get a super lean mixture big time melt down.
I doubt this additive is enough to do too much damage.
Nitrous Oxide
Ever ridden in a car w/ NO2 injection?
I did, once. WOW
I had no idea it 'kicked' an engine as it does.
Can double the horsepower.
Thanks. I didn’t think the results could be very good. Definitely use this stuff at your own risk.
I was thinking more of something you could put in your tank rather than having to install injectors and a couple of NO2 cylinders. I have a friend who has a car with two huge NO2 cylinders in the back. It is insane.
I wonder if it would have a similar improvement if added to E85. Running E85 dropped my mileage from 16.5 combined mileage to 13.6. 10% improvement would get me back at least part of the loss...
maybe nitromethane?
sidenote....at the root of the O2 sensor/ECM theory is the idea that combustion requires O2.....therefore, just a smidge of O2 remaining after combustion is witness to burning all or very nearly all of the fuel (gasoline, acetone, gumout, propane, or whatever, LOL). Calibration of the fuel map in the processor and other sensors/actuators allow for appropriate deviations from stoich (0.45V/14,7:1 air/fuel ratio).
The bit of witness-level O2 that we live with is only because a mini 4-gas analyzer is impractical....the O2 is a partial and INDIRECT look (based on the above) at what is passing out the tailpipe measured before and after the exhaust catalyst.
Horse manure! Your invention? Everyone knows its GENETIC in politics! ;^)
That would be my concern.
That parallels another explanation which was on the auto forum where I first read about Acetone. I'm just glad it works on MY car!
And E85, Batt? Dunno, try it and report back, ok??
There are a number of ways to increase the oxygen payload on the air intake: Cool air intakes, intercoolers, methanol injection, water injection, propane injection. There are fuel additives to increase oxygen as well: Ethanol, Methanol, MTBE, whatever Michael Waltrip put in his tank at the Daytona 500!
Ed Schultz the Al Franken of Fargo...only not as funny.
"And that brings it right back to running on beer, but with a drunk driver at the wheel."
Not in my case. In the early 70's, I bought a '67 Chrysler Newport while in HS with an after school job. My dad said "That car is going to run on piss." He was right. It got 4 mi/gal. I should have kept the '64 Valiant instead of trying to be a big-shot.
Those 6 cyl Plymouth Valiants and Dodge Darts were indestructable.
I think engines running lean run hot, an engine running hotter than it was designed for disintegrates quicker.
Most of Ed’s audience apparently do not have jobs anyway so I guess if they ruin their Ford Escort with 250,000 miles on it they just go to the nearest junk yard and pick up another.
