What if this

!!! UNKNOWN CONTENT TYPE !!!

Was combined with this

Its condensed water and its filtered so it should be pure enough to not cause issues with the injector or with cylinder deposits. And if you are putting in a water system with pumps and tanks, why not add the small extra step to generate it onboard? At 1-2 liters per hour it seems like the condensation system would be able to easily and indefinitely supply the water need (which looks to be about 2-5 liters per 3000 km from the video). Since ford is already hot and heavy into the Turbo DI, it seems like this would be a no-brainer next step for performance vehicles or mainstream.

Thoughts?

Hmm, good point. How does the m3 gts solve this?

brb, submitting this idea into our “innovation challenge” at work (bosch).....

Interesting video.

I was on-board with the concept until the video reminded me that there would have to be an entire supporting system (tank, pump, etc.) cluttering up the engine bay. No thanks, it’s crowded enough under there as it is.

All the water is pushed back to the tank when the car is turned off so the lines don’t freeze, and the system is not used if the water is not liquid.

Boom, solved.

I was also wondering if it could reroute to spray on radiator

And also why it won’t become mainstream. If it doesn’t work when it’s below freezing the idiot larger public will only bitch about it.

which is too bad.

I get 20% of the winnings, unless it’s cake...then it’s 50%

BMW puts it in the trunk. There’s just a little tube and three nozzles which squirt water into the intake charge.

All of it? The tank, filter (I assume there’s a filter), and pump?

Looks like it. They have it set up just like a fuel tank is set up. Here’s BMW’s article on it.

Interesting.

I don’t see a return line in their pic, so I wonder if the pump switches to reverse flow for that freeze protection feature.

I think those injectors act like fuel injectors. It probably just doesn’t squirt if the lines are frozen. With the lines being in the engine bay, they probably thaw pretty quickly if frozen. I’m sure all these cars are kept in a climate controlled garage anyways.

That article claims that the water is returned to the tank to prevent freeze damage. Whatever method they use to accomplish this, I still don’t understand how the water in the tank is kept from freezing. A heating element, perhaps? I don’t like the thought of something draining the battery while parked, though...

Yeah. I would mix a little meth in there with it.

crazy alternate is to have 1 piston not connected to the crankshaft, but instead to a generator to charge hybrid system. Could use excess heat from the exhaust.

like a double expansion system?

Why not a triple for the hell of it?

I imagine the weight may offset any performance boost.
