MotorcarsMahindra,
THANK YOU so much for all the info!!!

We've been kind of starved over here if you can't tell.

Question for you on the DPF:
Do you know if the regeneration cycle includes an injector in the exhaust manifold or are they injecting the fuel in-cylinder with the existing injectors?

ie. In 2011 GM is switching to installing an injector directly in the tail-pipe assembly to inject raw fuel to clean the DPF. Ford may be doing something similar with their now B20 compliant engines.

In 2007 when all the DPF's came out, there were several problems with fuel dilution in the engine oil due to the injectors spraying the unburned fuel in the cylinders and not having all of it vaporize & head down to the DPF for the regeneration cycle. This became particularly problematic when folks ran Biodiesel in the engines.

GM changed the Duramax to deal with this by putting an injector outside the cylinder & Ford "claims" now to have B20 compliance for Biodiesel so my guess is that they've done the same. Mercedes Bluetech system as I understand it still uses a in-cylinder regeneration procedure; which means no more than 5% Biodiesel.

Any word on how Mahindra's engines will regenerate their DPF's? ie. in cylinder or in the tail pipe?

Thanks for the info. I'm loving having some fresh news again!

The Mahindras willl use the Urea tank system as found in the Mercedes Benz Blue TEC. Here is a little blurb I found online about the Benz system. I have yet to see anything from Mahindra explaining more. This was all verbal meeting stuff with a factory rep. Again keep in mind this is Benz info but it is what the factory referred to when explaining thier system to me. Apparently both are designed by Bosch.

Owners of the new crop of clean diesels will have another maintenance item to concern themselves with if their new cars are equipped with urea injection. The EPA requires that all diesels meet strict new emissions standards, which almost always requires the use of either a NOx trap or urea injection. To ensure that the system is working, a sensor checks both the level and the quality of the urea solution and will keep the car from starting if the tank is empty. The new VW Jetta TDI doesn't use urea, but the new Mercedes-Benz BlueTEC vehicles do. According to Mercedes, a counter will appear on the dash when there are twenty starts remaining. If the driver ignores the message, the car will not operate until at least two gallons of urea solution is added to the tamper-proof tank that resides in the spare tire well.

Engineers have designed the urea tanks to be large enough to last about 15,000 miles. This should be large enough that drivers never run out, as the tanks will be checked at every schedules service. As an alternative, small bottles of the urea solution will be available for owners who want to maintain the system themselves. The cost of the urea solution, which MB refers to as AdBlue, will mirror the cost of diesel fuel, so a refill shouldn't cost more than $30 or so. Before anybody asks, yes - urea is a component of urine, and no - peeing in the tank will not fool the sensors. You've been warned.


Here is a related Article on Urea Tanks. Hope this helps a little sorry I don't have more to give you right now.

Chris,
I love your new tagline!
"Providing more information about Mahindra than Mahindra even knows since 2008... "
ROTFL!!!! That's awesome!

Welcome Motorcars Mahindra, look forward to workimg with you. I like all of us are starved for correct information. The last newletter I received said "they are on the way"
We need more details.

Wow, the are only sending the information out letter by letter. We all knew they were stingy with their info. Shades of Sesame Street,

Thanks DFW Mahindra, Looking forward as well. I was wondering if you received the information wall for your showroom and where you stand with Pattison on the sign?

[howam00]

Any chance we could get you dealers to take some pictures of this new "info wall" and any other materials that will be up in the new showrooms?

Hopefully that isn't against anyone's policy but it would be cool to see.

[pee wee]

Don't let the last couple of days scare you, we're not usually like this on this forum. We love all people associated with bringing Mahindra to this country, especially the dealers. We just need to keep in mind the expression "no news is good news" and we'll be happy- as long as we stay on our medication. hahahahahahahahahahahaha
