Particulate filter delete

[tomt574]

In the '60s (late) America's cars had carburetors and point ignitions. In my neighborhood there was a car from the '40s or '50s on every other block.

There might have been a few 40's '50s cars in LA then too unless they rust out younger than around here where we build 'em. :scratchchin:

So far in the '20s, I'm happy with my own Tier 2 & 4T CUTs and with doing my best in the Midwest for clean air in Michigan's basins, too.

Yes huge difference in carburetors and point ignition vs electronic fuel injection and electronic ignition. I love the features of my new model tractor just hate the regeneration system. Im sure with out it instead of a 55hp tractor it would be a 60hp tractor. It is amazing what happens when you let it breath.

The DPF isn’t a giant cork in your exhaust system. It’s either a porous ceramic matrix that you can actually see through or a metal matrix, along with some catalyst materials. The DPF essentially replaces the muffler, so there is no power loss due to increased back pressure.

Why this hate you talk about? It isn’t rational.

Im not talking hate and I am very aware of how the DPF and EGR system works. Your statement on it not causing back pressure tells me you do not understand how it works. A DPF filter has a differential pressure across it. When that set DPF is reached a command is sent to burn it off using what ever the media is for that system. Urea, Deisel..etc. you can not have a Defferentual without back pressure. I work on the all the time. As your DPF gets older it will take less time to accumulate particulates do to built up residue. I have removed many and seen the difference in horse power as well as fuel economy. I have also had to install them and seen the lack of efficiency. Please spare me the bro science. FYI, a DPF does not essentially replace the muffler. 2 totally different animals. A muffler does exactly what it says. Muffles sound. Geez man, please

Not trying to talk hate just facts. Apparently if someone has something that does not go in line with what you assume then its hate. I deal in facts not ********

There痴 a huge difference between a 10 year old tractor that runs with hardly any noticeable emissions and a 1960s diesel that bellows smoke constantly.

Yes, well said. You make a good point.

And although I wish we could have gotten here without regulation & enforcement, human beings just don't seem to be capable of doing so.
Afterall, the air belongs to everyone. I'm proud that our's is good enough to share.

Then, why there are couple threads where the DPF plugged so badly that the engine wouldn't even turn? And the dealer had to take the emergency plug out of the DPF so they could load the tractor?

I'm guessing you haven't had any emissions issues yet. Unfortunately, it's just a matter of time though.

I was told diesel soot becomes a ground pollutant as it eventually falls to the earth? How long the particles å��loat in the atmosphere would be interesting to know. I realize air temp, winds, etc are just a few of the influencing factors. It just make me wonder how much good it does for the particles to be super small and suspended in the air rather than bigger particles falling to ground faster? Then there’s ´ ground pollution from soot, a whole 創other topic.

I have 3 6.4L Fords in my truck fleet and they have been a love/hate ownership experience. The engines run super strong, which I love, but the hate revolves around the DPF.
I notice periods of super smoke clouds, yet my tailpipes look like shiny silverware. Very little exhaust tip soot staining. Does this mean the big exhaust clouds are made up of fine particles? Or is it irrelevant. During these periods of smoke, some of the more friendly fellow drivers greet me with the universal greeting sign as they angrily accelerate past me.
I don’t know all the science, just everyday practical use. The DPF on the truck isn’t a fun accessory to operate and maintain. Had one “concerned environmentalist” actually get out of his car at a red light and tell me what a horrible person I was.

I only worked on Diesel Perdormance and emissions for thirty five years, in product development engineering for a Diesel engine manufacturer, so what do I know?

Yes, there were some teething problems, but a properly functioning DPF is relatively seamless, and raises back pressure an inconsequential amount.

Apparently part of what you do not know is what happens to these engineering marvels in real world conditions.

Yup.
