vacuumizing fuel for better economy

So we are doing a form of lean burn, then. Okay. I figured as much.

Just be careful. Lean burn is okay at cruising, but if you try to load the engine too much while in lean burn mode (like trying to accelerate or trying to tow something at cruise), then you'll rather quickly melt something inside your engine.

^ Being vacuum operated, it's got a built in safety for that. The more pedal he gives it, the less vacuum, and therefore the less vapor pulled in from the jar, reducing the effect.

that alone will boost your fuel economy significantly...

first off
the 02 sensor does NOT see 02 , it measures presence of
COMBUSTIBLES
not 02

2nd
on your system , with 02 sensors
it can only operate at 14.7 to 1 or stoich because the 02 sensors can only operate at
14.7 to 1 so your system is operating at stoich

adding supplemental fuel through a vacuum line can not cause the system to operate in a "lean condition"

therefore
the amount of fuel you use DOES NOT CHANGE
you are adding fuel from another source and claiming you do not need to figure the additional fuel into your FE calculation

but
as you have been told already

you are wrong
your claims are FALSE
you need to measure and add into the FE calculations all of the fuel used , including the fuel in your contraption .

stop your HOAX
quit while you are behind

just because you are unable or unwilling to comprehend the theory involved does not mean that the theory does not apply to you .

swiftbow - yea i was thinking psi but i was looking online and was told vacuum is in inch pounds so i went with it but i thought it was kind of wierd for a vacuum pump manufacterer to go with psi if it only used inch pounds so i was told wrong

cortez - the jar only adds gas in it's atomized form so then it burnes almost instantly in the combustion starting the burning of the injected droplets of gas quicker so they burn more thoroughly or so i've read, so then the lower amount of o2 in the exhaust tells the computer that your running rich and leans out or so i'm also told.
========================================
intake manifold vacuum and MAP are measured in
inches of mercury or kpa
the MAP sensor is the primary load sensor on your system
MAP = BARO - intake vacuum
MAP = manifold absolute pressure

Geez, crucifying him for so little!

Stovie, run a tank with the mod and a tank without (or more). Don't trust any measuring device since you're feeding your system from multiple ports.

i did and only used a little bit over 1/3 of a gallon "IN THE JAR' throughout the hole tank so that should of only add 7 miles to my hole tank but i hit 28mpg stop seeing what you want and look at what i'm saying!!!!!!!

[mwebb]

all cars
have an evaporative emissions system
all cars
use the evap purge valve to
apply intake manifold vacuum and extract fuel / hydrocarbon vapors stored in the fuel tank and charcoal canister in the course of normal operation

what ever benefit you think you have created
is already present on each and every car sold in USA
including your own

that is three strikes
you are out

your HOAX has been debunked - again

thank me very much
quit
while you are behind

it is time for you to hit the books , study and learn about the systems you are thinking to modify
before
you modify them and make false claims regarding your bogus modifications

yes my jeep does have a evap emissions canister and it only sends 1/2 a pound of vacuum to the back tank why because it's mostly to reduce the release of gas into the atmosphere it even says that in the manual what i am doing is completely different in that i'm using the vacuum pressure to evaporate the fuel rather then just to keep the vapor in the tank from entering the atmosphere i have proof in my A-B-A testing that shows the difference in fuel use and i'm sorry but you are yet to debunk my "HOAX" as you put it. I have seen the increase and am going to voice what i've seen with my own eyes as long as it works so deal with it!!!!!!!

[some_other_dave]

Very neat; A-B-A is a good indication that it's working. I assume you drove exactly the same way for all runs, hopefully measured by something or externally controlled by something (e.g. cruise control)?

Wonder if you would get the same (or even better?) improvement if you used water (or alcohol) in the jar instead of gasoline...
