I reassure you the engine (at least not too dumb because of nulls it exists ^ ^) are aware of the injection of water, its advantages and disadvantages ...

The answer advanced in the video that "the test benches are not suitable for this type of system"does not seem to me very credible. Does anyone have another explanation?
I seem to have given it many years ago, so I will repeat myself but it is for the good cause ... thank you for relaying this info (citing this message or econology is better ...)The water doping works OK (I speak at the consumption level, on the particles it works all the time) only when the engine is very loaded, ie it is asked a lot of power, I would say at least 80% of maximum power
So, it's huge, on a car of 100 cv it means to ride at 170-180 km / h ... since driving at 100 km / h only requires 20 30 cv power (hey yes ...)
The tests I started on 2005 on a tractor, it was necessary that the muffler is red to measure an effect (memory I think 35% reduction in consumption ... red pot!)!
It is to situate you the thing ...In short, it takes high temperature for it to work!
Be sure that the builders' engineers know all this (but they do not want to say it ... for some reason I do not know ... follow my look ...
This easily explains:
a) The little or no measurable results on cars because we do not pull enough in it (except at big accelerations) + lack of electronic management
b) Lack of generator result because the engine never exceeds 80% load for design reasons (over-sized motor of at least 20% relative to the generator to absorb peak current and avoid engine stall)
c) The good results on the tractors because they can work "in depth"
d) The test bench cycles are rarely done at high load, especially the manufacturer's standard cycles, we just make "peaks" of power so as not to damage the engine (a tractor engine, so industrial engine is designed to run at 100% "all the time", not a motor vehicle) anyway that has access to a real bench to move things forward? That engine manufacturers and they do not want this system ...
e) The use of water injection officially on heavily loaded engines: 2ieme GM fighter, 1 80 formulas ... See:

f) Last remark: the race to the power of the car manufacturers is, necessarily, not favorable to the use of the injection of water, the engines are less and less solicited
Thank you for sharing this message if you want to get things done ...Too bad I was not interviewed for this film ... because I would have clearly explained this in person ...
