...you need more variables Andrew...and make them Greek letters ;-)

Sure, the 'net enrgy' may be a loss, but the cost of electricty/unit of energy and gasoline/unit of energy I doubt is the same.

THen there may be 'synegestic' effects of blending some hydrogen with gas/air. Perhaps it helps it ignite better or something..

Sort of like Nitrous Oxide, only a more pronounced effect? :-)

if the car is the same, but mileage increases then there is either an increase in efficieny as some claim or an increase in energy supplied to the engine which is then falsely percieved as an increase in efficiency.

Injecting Hydrogen is the later which is a combustible so more energy is being insertedinto the engine. To make hydrogen requires more energy than expended. It must because of conservation of energy and if otherwise, we'd have a perpetual motion machine. So if a net increase in mileage is reported over a full tank of fuel with no power being pulled from a wall source, there might be impact to the engine's efficiency.

Water injection has been used in engines since WW2 to obtain more revs especially at high altitudes. If you burn hydrogen the resulting water would likely stay as steam, it would do all types of funny bad things to the O2 sensor and such. The engine's operating temperature would decrease due to the water in the combustion chamber. I would think this would have a negative effect on the gasoline portion of the combustion.

<center><img src="http://upload.wikimedia.org/wikipedia/commons/thumb/3/31/Godiva_statue.jpg/456px-Godiva_statue.jpg"></center><p>From the Mac Eng web site (verses vary from school to skule). "Sung"...or shouted...to the Battle Hymn of the Republic:

Godiva was a lady who through Coventry did ride,
To show to all the villagers her lovely lily-white hide;
The most observant man of all, an Engineer of course,
Was the only one who noticed that Godiva rode a horse.

Chorus:
(sung after every verse, just incase you don't know music)
We are, we are, we are, we are, we are the Engineers.
We can, we can, we can, we can demolish forty beers.
So come, so come, so come, so come, so come along with us,
For we don't give a damn for any old man
who don't give a damn for us.

"I've come a long, long way" she said "and I would go as far,
With the man who takes me from this horse and leads me to a bar."
The men who took her from her steed and stood her to a beer,
Were a blurry-eyed surveyor and a drunken Engineer.

My father was a miner from the Northern Malamute,
My mother was a mistress from a house of ill-repute.
They kicked me out at an early age for drinking' all their beer,
Saying "To McMaster, you son-of-a-gun, to be an Engineer!"

The army and the navy boys set out to have some fun,
Down at the tavern where the fiery liquids run,
But all they found were empties for the Engineers had come,
And traded all their instruments for gallon jugs of rum.

Sir Francis Drake and all his ships set out for Calais Bay,
They heard the Spanish Rum fleet was headed out that way,
But the Engineers had beat them by a night and half a day,
And though as drunk as hooligans, you still could hear them say;

An artsie and an Engineer once found a gallon can,
Said the artsie to the Engineer "Outdrink me if you can."
The artsie had three drinks and died, his face was turning green,
But the Engineer kept going, it was only gasoline.

A maiden and an Engineer were sitting in a park,
The Engineer was busy doing research after dark,
The scientific method was a marvel to observe;
While his right hand wrote the figures,
his left hand traced the curves.

On reading Kuma Sutra, they tried Position Nine,
For proving masculinity, it truly was divine,
But the woman soon grew tired and she threw him on his rear,
For he was just an artsie and she an Engineer.

Venus is a statue made entirely of stone,
There's not a fig leaf on her, she's as naked as a bone.
On noticing her arms were broke, an Engineer discoursed;
"She's a busted hunk of concrete and she should be reinforced."

My mother peddles opium, my father's on the dole,
My sister used to walk the streets, but now she's on parole.
My brother owns a restaurant with bedrooms in the rear,
But they won't even talk to me, 'cause I'm an Engineer!

So now you've heard our story and you know we're Engineers.
We love to love each other and we love to drink our beers,
We drink to everyone we see who comes from far and near,
'Cause we're a HELL-OF-A, HELL-OF-A, HELL-OF-A, HELL-OF-A, HELL-OF-AN-ENGINEER!!!

Godiva Historical Note: For those who must know, in the year 1040 -according to legend - the people of Coventry were suffering from heavy taxes imposed by their lord - Leofric the Dane - in order to finance his battles. Leofric's sympathetic wife, a lovely Saxon named Lady Godiva, was determined to convince him to reduce the taxes. Leofric declared that Lady Godiva was shameless to plead for "the whining serfs"; she responded by saying he would discover how honorable the serfs were. A deal was struck: Lady Godiva would ride unclothed through the streets of the city, "clad in nought but my long tresses," and if the population remained inside shuttered buildings and did not peek at her, their tax burden would be lifted. The following morning she made her famous ride and the citizens of Coventry graciously stayed inside, to spare their benefactor any feelings of shame. Leofric kept his word and reduced the grateful people's taxes. What this has to do with engineers... I have no idea, but it's a great story.

Maybe write them in russian.....

Yep. We need more than 26 variables.

Katman

We could use 'NLA Audi part numbers' as variables.

No Problem, as Audi isn't using them any more, and plenty of them to go 'round...! :-)
