New OEM water injection user

[Flr Power]

Staight from autoblog:

In practice, the pump feeds the water to the injectors at a pressure of ten bar, whereby the appropriate volume is supplied depending on load, engine speed and temperature.

Thanks Fir Power.

Richard, could you post the sentence were they mentioned the 10bar system ?

Sorry, I was confused with a different article. here it is:

Do have a copy of the "WRC rule on water injection"?

I was told by our customers, WI is no longer allowed from 2006. I did not look into this in any details, just accepted it.

I did write to FIA to unbanned it with almost all the benefits highlighted by the the current BMW blog. I never received any reply.

I attended and spoke out one of the official motorsport conferences called "Green Motorsport", no results on that either. During the conference I raised the topic of applying water injection on reducing nitrous emission on road cars but he dismissed the idea and assured me their FSI technology has taken care of this.

Currently, cars with 3-way cat (95%) uses nitrous trap, and purge them with occasional CO rich exhaust gas. If you are interested I will try digging out the article. They called it "Lean Nox Trap Regeneration", technical or simply "dumping fuel".

"LNT regeneration was performed at an AFR of 12 consistently over
the load range; however, during lean operation the AFR varied with engine load and spanned from 19-28 with the lower AFRs occurring at higher loads."

19-28 ?? I thought 19 is the maximum lean possible !

Not sure >18AFR will ever work under load, possible just keep the engine tickinh over on gear neutral?

I agree with the >18AFR, but I don't understand the second sentence
