18 microlitres per injection is need to run a dunebug engine of VW.....

In ithe SEER94 info, I took the 18 microliter figure as meaning 18 microliters per injection per  cyclinder

For fun, take the number of cyclinders in his Dunebuggy engine times the number of revolutions per minute
to determine an estimated water usage per minute.

Sources for rpm would include:
Analysis of the audio of dunebuggy demonstation filmed by Marilyn might give an idle speed.
In the 1992 GMS explained tape released by Dynodon, Stephen mentions injector firing rate and relates it to engine speed  ( 50 -60 mph).
Published sources such as Chiltons will give a tuning guide to the engine.

Then look at the WTVN video segment where Stan is giving an estimate of the number of gallons to drive
to Los Angeles.

Determine the miles  from New York to Los Angeles using Mapquest or some trip planing software

So is Stans estimate correct?  Post a reply  and Show your math

His numbers weren't estimatives. He used 44ml per minute for the buggy to run, which sums 2,64liters of water per hour... at 65MPH speed!!!!!

In terms of gas around 4750 liters of gas per hour, 1.3 liters of gas per second...

if i remember well steve he stated used 7uL per injection cycle--- 44ml/min/60s/100injection/s=7.3uL

at 3000 rpm 50 revolutions per second being a four stroke engine there are 100 injections per second... because each two revolution each cylinder will have fire...

thereto 13ml of gas per injection... in the 4 stroke motor 1600cc each cylinder has 400ml capacity...

In terms of energy efficiency

assuming 66 watts per mole of water(18g) as ideal electrolysis it turns out to be 9.7KW of power. 100% efficient or so

those are the magnitude orders ..

45 h (2.64 l/h) = 118.8 l or 31.3 gal h2o for the trip which is fairly close to Stan's statement in the WTVN
interview of roughly 22 gallons of water

In what video,patent or document is the 7 micro liter figure found?

2800 mi/ 22 gal h20 = 127 mpg of H2O. This give a whole new meaning to the phrase "one tank trip".

Whether or not it's 7 uL as in the Tech Manual or 18 uL as in the SEER94 materials, the Dunebuggy in
its various configuations was an amazing piece of technology

Well that is for sure... a master piece of engineering...

I think didn't saw that this seer94 ducument... where is it please?

probably 18uL was the first version of the buggy...

the 7uL figure might have the Gas processor added... later maybe...

I found this post.
Its  interesting, i think.

Great info Duncan.

He talks about using around 32V
Anyone know how many amps it takes aprox?

I like to make a small scale version to play with.

I designed something similar a few years back, but never built it. It's on the forum here somewhere, here is a pic:

Here is my little "Sparp plug" version :

Water under slight pressure comes in Glas tube trough one way valve
As the water level touches both the electrodes, the gas vorming starts.
An Underwater spark is formed between the two carbon balls
Gas forms and is pressed out of the tiny opening at the plug head
As all the water has turned to gas, the the Tungsten Spark head will become the lowest resistance and sparks the gas.
This way only one continues voltage needs to be applied. ( In my theory/fantasy at least ;-)

Around it I have an energizer only connected to one terminal, The pos or the neg, may change i will see, but the energizer coil will only be connected to one terminal.

I never made it, but it starts to itch again..
