[W126 Coupe] Water4Gas.

[John Howard]

I was actually being generous with the 30% efficiency number, the most commonly accepted efficiency rating for gasoline IC engines is about 25-26%.  Diesels are generally closer to 30% or a little better.   There has been research on the use of HHO or H as a “catalyst” or combustion improver, but it applies only to very special IC engines in laboratories, not on the street.  And it still would not justify creating HHO or H by the very engine that would use it.

 

HOWEVER, if one were to use a fuel cell technology like the Bloom Box <http://www.bloomenergy.com/>  (50% efficient) to turn H, LNG, or methane into electricity to drive an electric motor system, NOW we’re talking!  If only a Bloom Box were available in the small size yet, if there were a ready source of hydrogen, etc. J

I would totally agree with John and Jono below... 

The biggest problem is the IC engine and the system of mechanical power transfer that follows it regardless of the fuel feeding it.

It's a 30% efficient system which by any standard is despicable! An IC engine that produces say 300 HP at the wheels is actually making around 1,000 HP at the combustion chamber.

That means that around 60% of the energy is dissipated or "discarded" in the form of heat out the exhaust pipe, radiator, etc... and friction brakes.

Bottom line is that the IC system is a dog, no offense to dogs, compared to an electric motor drive system which can achieve 95% efficiency with regenerative braking capability.

Now, that's a worthy pursuit...! Anyone converting SEC's to electric?

p.s. Can't anyone post the article from March/April issue of The Star Magazine that Chet spoke of a while back?

Orrrr, am I going to have to go to Borders? Geeez! ;-)

I had a friend of mine fiddle with it on behalf of a business guy that
wanted to sell these during the $4 /gallon gas days. He mentioned something
about leaning out the engine and backing out the O2 sensors but he never got
the cars to run right.

Does this use electrolysis to create the hydrogen? If so, i'm not sure how
much hydrogen can be created see some real benefit.

Propane is a hugely successful fuel Europe and unlike CNG, you can really
run a car on propane as a dual fuel car. There are tanks that are designed
to fit in the spare wheel well and while you wont gain MPG, you should be
able to greatly reduce your fuel costs.
