Nobody said that, at least not me.
Personally, I have no doubt that the injection of water, steam, humidification of the intake air, can reduce NOx emissions. It has been for a long time (at least 30 years) used industrially in combustion turbines.
Now you have to read the Bureau Veritas report: their mission, and only that one, was to measure emissions between test 1 and test 2. Everything else, read the report carefully, is the responsibility of the "customer" .
Whether 12 days have passed between test 1 and test 2, whether the vehicle has traveled nearly 1000km between the two tests, whether the bench has been adjusted or not exactly the same, all this is not theirs. problem. When the customer says "go", they take a sample for 5 minutes and provide the analysis results.
So be careful about the results in terms of consumption.
You think that an entry-level diesel car manufactured in 2005 would have sold with a consumption at 3000tr / mn in 5ème of 8l / 100km of diesel ????
Edit: on the flat, without wind, without gallery, without trailer ..... of course
