H² + H²O = 25% More HP

let me get this out of the way. for economy I know most of these hho and the likes kits are snake oil.

heres another spin on it.

can the combustion chamber cleaning abilities and lower emissions be worth it in the long run?

as in would it be worth it to but out lower emissions and keep your engine free of carbon deposits etc that could lower the economy anyway?

Decoking was something that only needed doing when petrol didn't have the detergents etc. it has now, and for the bits that misses I understand there are potions, ungents and other magic spells ("seafoam" I think is one in the colonies, we use carb cleaner or Redex) which perform the same role in one go ?

Better than driving round with a permanently powered Unicorn feeder leeching off your car, no ?

Like I tapped - if it worked it would be on every car - and would be tuned, perfected and advertised as a feature.

I'm thinking (not making any claims here) that perhaps the best way to use water to increase efficiency is to try something I think was called a six-cycle engine. After the fuel powered four, another involves injecting water into the hot cylinder, which turns to steam and applies pressure to the piston.
There'd be some engineering involved, with timing for ignition and injection, you don't want to cool the engine too much with the water injection, so adjustments would have to be made there...
Still, a lot more believable to me than the HHO fad.

[racerc2000]

how bout 2 injectors for each cylinder? one for water one for fuel and they just swap back and forth for every cycle? or just add a set amount of water in every cycle.

but then again that would be 2X the fuel tanks, lines, pumps etc.

it would let you run a more advanced timing and high compression and still use low octane fuel. or on some cars lower the oem requirement of high octane fuels
maybe even lean the mixture and still be safe.

it would deff need quite a few hrs on a dyno to perfect though

Yeah, it'd need another tank and pump... don't know exactly how much water it would use per cycle, but that's one of those things that a bit of math and a bit more experimentation would determine.

Crower six-stroke engine

In a six-stroke engine prototyped in the U.S. by Bruce Crower, water is injected into the cylinder after the exhaust stroke, and is instantly turned to steam, which expands and forces the piston down for an additional power stroke. Thus, waste heat that most engines require an air or water cooling system to discharge is captured and put to use driving the piston.[8] Crower estimated that his design would reduce fuel consumption by 40% by generating the same power output at a lower RPM. The weight associated with a cooling system could be eliminated, but that would be balanced by a need for a water tank in addition to the normal fuel tank.

Very interesting. Someone with a bit of knowin' and a machine shop could probably do a bit of work on this...

Bruise Crower's 6 stroke was patented no later than 2006, probably much earlier but shows no sign of moving beyond the prototype stage. IIRC the problem he's had is acidification. Hot exhaust gases and steam will chemically 'crack' into all sorts of organic compounds, but the acids are the ones that will kill the engine by reacting with hot metal. Potentially you might need a far more complex catalytic-converter as well, I don't know.

This isn't like evaporative charge cooling (injecting small amount of water into inlet air) this is Lots of water in contact with hot metal surfaces. Very hard to get right if possible at all.

Great water injection link:
