"Water in Gasoil" documentary on water injection, car manufacturers know!

It's a bit ambiguous, however there is a mini bubbler with water on this video:

There is perhaps an advantage with this Econokit Gas because apparently it also recycles nitrogen and CO2 therefore less oxygen detection by the probes (?)
This is an advantage because steam (in small quantities) provides oxygen.

"Econokit is a company which HAS DEVELOPED a system to reduce pollution ... blabla"

But of course ... pfff what a world of ingratitude!

On the other hand, well done for their marketing "at the top"!

We already talked about econokit gas a bit here: https://www.econologie.com/forums/econokit-e ... 6-395.html

"Autoplus" tested it:

3.6% savings for diesel, that's 0.23 liters per month for 100 km or 230 liters for 100000 km: around € 300 of fuel saved over 100000 km ..... € 300, that's the price of the installation of an econokit.

Not very convincing

... worse! Mediocre results in the pollution test for an assembly, however well done;
here.
(It looks like Alexander of the Cornerstone).

Maybe the engine is descaling ...

But how can we measure CO2 in grams per km in neutral with a probe in the exhaust ...

This is not serious.

This is not serious.

This is the standard test during a technical control: okay in slow motion, then accelerated.

They even speak of a placebo effect !!

It is an absorption coefficient in m-1, nothing to do with CO2 ...!

(edit: I don't know which unit is used in this case, but it is related to the particles or the opacity of the gases)

And it's very easy to get different results, with the same vehicle.
Just heat it well by firing at full speed for a few kilometers to lower the value by half.

+1; It's easy to make this test say anything. During the last technical check of one of my R19s, the guy slows it down for 25 minutes before taking the measurement !!!!, while I brought it very hot. (I had done some "sport" acceleration on the road to clean up the pot just before .....) He told me it's normal for people to smoke, they get dirty in town ..... And slow down right?

In the video above, the journalist who claims to be a scientist with his measurement with a flow meter ..... He apparently did not make a real reproducibility test under the same conditions to see the relevance of his measurements. Reproducibility is already within 2% on a good engine test bench with a maximum of instrumented and perfectly framed parameters, so a measure of unprofessional on the road with all its variables ....... He can already announce from his office and without having left the result that he wants to change to 3 digit after the decimal point ....

The other one which compares the pollution of 2 different vehicles of the same model. With all the measurement uncertainties on an engine, plus the history of what he did a few seconds or minutes ago, it's already not easy to interpret, but there he compares with another engine, other conditions, another measuring device? ..... any quouak!

hi everyone, i just opened a new subject on the econokit i just bought, and i ask for help.
https://www.econologie.com/forums/econokit-v ... highlight=

moreover I just received the lexia to make measurements, it should be able to bring interesting data.
But I need time to properly install all of this.
