I don't venture into these forums much because I feel I'm in way over my head.... however, I have been browsing around and found quite a few problems with the DPF. I have been interested in buying a new 6.7L, so I'm trying to understand how the new emission systems work. My understanding is the PCM burns off the particulates built up in the filter under certain parameters, IE mid-high temp running temperatures.

A few years ago I remember reading about a particulate filter that collected the deposites left over from normal running processes, and after a determined time an electrical charge is passed through the filter for "X" amount of time to burn off the junk. If I remember this was used mostly for off-road applications, but to me it seems like a simple solution to a common issue.

This may have been covered a million times, but I could not find much on my question through searches. Is there any reason manufacturers do not use a system like this? What are the drawbacks/advantages versus the applicable system? I enjoy the simplicity and economy of my now ancient 12V, but now and then I do feel guilty about the emissions coming out the tailpipe. Any insight is appreciated.

 

I never heard of a system like that but I would venture to say that it must not be too dependable or Dodge may have used it instead of the fuel hogging system that they ended up with.

 

Some info for that type of DPF.

Thats the one. rypos.com show applications on the generator page from 50-200KW. I'd like to see pictures of the smaller (200-300kw) applications. Also states maintenance is a visual inspection every 1000 hours. If they could make something like that applicable to personal sized vehicles, sounds to me like it would be pretty much bullet proof.
