[Vwdiesel] CR particulate filter

[James Hansen]

My Dad's 08 duramax has a particulate filter. Particle traps really aren't
the best thing going.  Mileage with: 12  Mileage without: 18.  I'm told that
every 900 km, the particle traps uses 11 litres of fuel to cycle it and burn
off the pesky carbon. Seems.... wrong. He promises to never drive it in
California.
If you would stop the fuel from going to the particle trap, it would
eventually plug and be expensive to replace.  EGR motors have the combustion
temps cooled so much to not make nox, that the trap would never get hot
enough to clear on it's own. Much better and vastly more efficient to run
the combustion temps really hot, then deal with the nox with a urea cat.

I don't think you want to stop the fuel from dumping into the particulate
filter unless you want it to plug sooner robing you of cash (very expensive)
and MPG. Only other option is to remove it and install a custom downpipe
(already being made) and then you HAVE to have a tune as well. But you would
want to be out of warranty. They have HUGE HP gains when that is done to
them. Said thing is that most diesels have this style of particulate filter
on them. Our lube trucks on the mine are over the road trucks and we have to
drive them on the public road once in a while to activate the regen process
as you need to be above a certain speed. I think it is the same on the CR VW
diesel as well.
