worth a read..

Indeed, i wish i could read that wack schematic they posted? What are those two different sized rings about? A multi nozzle array?...

Without trying to be a critic, i await to see what closed loop system they implement for when the espresso machine water pump, even mounted in a metal box, dies from having to pump a constantly varying water pressure loads for a few years.

you will get coffee beans out the exaust pipe.

not that good, you need a decent way to activate it.

I think that is in part 2

On a second look at the schematic, it looks like its a setup from a jet turbine, hence the "engine water pump" at the bottom left, and the duel staggered ring shaped nozzle array.

Those pressure regulators and the surge chamber sounds pretty trick. As for triggering, i would think the regulators would take care of that. Awaiting part 2 !

that schematic was only a reference point.

it doesn't use any of it.

it was just an example of where WI has been used and how.

AutoSpeed Water Injection System Part 2

Interesting. I do like their seemingly comprehensive testing procedures and logic.

Though it looks like they are going to position the nozzle before the air filter, claiming it'll will provide "proportional amounts of water : air"

I'm not so sure about this. The key IMO, is being able to tell the existing ECU (in AS.com's example, an OEM ECU) that the detonation suppressing system is working and to take advantage of this with more ignition, less fuel etc.

For the system to be really worth it, it should allow such aggressive fuel/ign that if the system ever failed to turn on, the motor would suffer serious det damage... this is all means, the control of water : air must be EXTREMELY tightly controlled, not "roughly proportional"

my 2 cents

I was looking forward to the 2nd part, but the results were a bit disappointing...

In saying that, I've got the tinkering bug again, and am going to slot in an intercooler water spray in the next few weeks.

well that was a farkin let down.

Not entirely, would be pretty impressive if they run that coffee machine pump for a good few years without issue.

Also, the IC intercool spray pulled like 25% more heat from the intake charge, then WI! lol.

Proper WI in the US is pretty big. Its essentially another whole fuel system, rail, injectors, reg etc. They add a water soluble oil to the water to allow Petroleum hardware to work and not rust. They run real 40% water : fuel ratios, not the 65 ml/minute AS.com are trying.
