We then questioning the potential for water injection to reduce toxic emissions, Including NOx, sir BMW (with gray hair, which included questions on the second) we said that it would certainly be possible, but that it was not a good technology for it.


The explanation would have been interesting .... Too bad there is not the slightest comparison of "pollution control" ..... well a mill like this, it is not designed to limit the nuisance.

In fact, this over-drive with if specific use of water injection, does not presume what will be produced in series and if there will be a gain or conso and pollution .... : Cry:

there is little doubt that NOx is reduced by misting water, as these nitrogen oxides only form at very high pressure and temperature.

the depollution of gases, both in NOx and in HC is fairly well known by these water injections, Maloche had moreover made eloquent tests on his "blue flame" boiler.

After that it is clear that this engine is too powerful and too big to do in the ecology.

Remundo thank you for the link.

In the original page it says:
"Asked whether M4 with injection of water consumed less, the answer is no. With or without water injection, fuel consumption is identical. The advantage of this technology is to correct a known through a turbocharged engine: the rise of the combustion temperature. Air, forced air, all turbocharged engines need a cooler, and water injection system BMW acts as a super cooler."

They have a com rather special indeed .... the key is to make the buzz? so that onlookers excited for or against? : Mrgreen:

This is the response of the brand manager to the question on the stand of the last auto show in Geneva by Laurent J. Masson.

Why they would have fun to make a bad com, they do not usually tell salads on this site.

We talked about it in the page just before

This is the tightrope in journalistic terms, but from the standpoint of engineering, given power, it consumes (a little) less, and the effects are noticeable at full load.

I did not see the previous page.
It makes sense that it allows an increase in power by prolonging the effect of turbo, when to save fuel, expect concrete results rather than journalistic speculation. ;)

Aloa!

We already know that it is effective 8)
But the results are auregard perspective EGR valves already installed, which recycle water vapor exhaust

We bet, with water injection, EGR valves will be deleted?

Hi Maloche,

Yes, except that the EGR works only in low to mid ... ie it is OFF from a certain power / engine RPM ...

I noticed this by connecting an OBD beast 15 € linked to an Android ...

Or is that high power water injection is the most effective ...

Also there is no EGR engines on gasoline ... (I think?)
