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!
