Water injection makes a comeback on production vehicles -
I guess it’s time has come, since we’ve “conditioned people” to add *extra liquids* to our vehicles regularly (with DEF or Blu fluids)

The only people yet "conditioned" to use these systems are the people that would have had them installed anyway.

Expecting Karen across the street to add water/meth to her Honda won't happen before the ICE is dead.

BMW/Bosch has had growing pains with this system. Of course it's not as bad as the instances of coolant* leaks in the air/water intercooler.

*The induction system has its own coolant system for the air/water intercooler.

The OPE referred to DEF. If Karen drives a diesel, she doesn't have a choice.

Outdoor Power Equipment?

Yes, the OP mentioned DEF, but that too is going away for your average car. Mainstream diesel is dead, and there will never be mainstream water/meth injection.

There are a few ways to recover the water from normal operation. First, the air conditioner often produces significant water from the evaporator. Second the exhaust contains significant water and it's not all that difficult to extract and filter.

The Bosch system requires distilled water and contains ultra fine solid block filters.

Good luck making that much water in the winter time up here when the air is super dry.

Don't need water injection at low temperatures. Engines already have higher thermodynamic efficiency due to colder ambient, and the air density allows for more air to be compressed by the turbo and crammed into the cylinders without exceeding the EGT limits.


Seems like a gimmick though.. Who actually wants/needs this extra horsepower? We're not talking about big rigs or aircraft engines that may legitimately need a burst of extra power..

There's one engine that will not have carbon issues.

Water injected engines look like they have been scrubbed internally with a fine toothbrush. Shiny as the day built.

Dry winter air would have an impact on moisture from the A/C but not on moisture from the exhaust. It's academic anyway since any system that uses straight water would freeze solid when the vehicle is shut down below freezing.

Water injection usually uses a 50/50 mix of water and methanol as this prevents freezing.

Water injection would certainly keep intake valves and piston crowns clean on DI engines.

Back in the 70s the auto parts store I was at ran a dozen vegas for delivery vehicles. All had the edelbrock water injection kit on them. Most of those vegas were the 75-76 models with iron sleeves and most went over 100k before engine fail.
They injected water thru the air cleaner lid into the carb throat.

I ran a ton of Pontiac engines for street/strip use and had an Edelbrock Water Injection unit on all of them. Only sprayed the secondaries, an extremely adjustable device with duration vacuum adjustment on the electronics and various orifice sizes to use.


Worked like a charm and let us run the timing WAYYYY up!
