DPFs (Diesel Particulate Filter) and a new model that could be great

It has to be CARB approved. In California, there is a warning not to buy or have a DPF installed if it's not approved by CARB. If you purchased any kind of DPF and it is NOT CARB approved, you just wasted your money. "BUYER BEWARE", check out there website. It's in bold letters.

 

Call me a skeptic but it sounds like you've found a good, new snake oil scam to rip people off. I can't imagine OEM engineers with million dollar budgets haven't been working to solve these issues themselves. Seems like most problems come from improper maintenance, excessive idling, and/or road treatment corrosion anyway.

 

Reliability Is the most important.....

Size and weigh are also a consideration..... Frame rail space is hard to come by these days.

Less dpf and more def seems to be the latest train of thought......

 

DPF technology is and has been obsolete even before it came out.

 

An exhaust that has a 50% mpg gain?

 

I'm confused. How can you increase the efficiency of an engine, increasing fuel mileage by 50%, by adding a restriction in the exhaust? What exactly is a filter doing if it never has to be cleaned (self or otherwise) or replaced?

In other words, not interested because it is not possible to do what you say.

As for how I've been affected? I can't go to Calif---ya...which is fine, because there isn't anything there worth making the trip. My truck was manufactured long before DPF was a thing, so I've never had to worry about an inappropriately timed regen or having to find a shop for more involved maintenance. The only place fuel lines run on my truck are to the engine...NOT to a ridiculously hot component of the exhaust where a truck fire is just a cracked/leaking fitting away.

 

Yeah, Sorry, but there ain't miracles. Dpf that does not need to be regened?! Am I supposed to dispose of the sooth every 2000 miles to a garbage can manually? Show me the blueprint, then I'll tell you If I buy it. Otherwise, I consider it another Turbo 3000 D or whatever.

 

In the last 2 years, I spent on Dpf (no def, just furnace and filters sensors 7th injector ) about 4k. I don't want to start talking about horrible fuel economy which averages around 6mpg, whereas others proudly brag about (rightfully so, I am just envious) hitting almost 8 mpg with preemission trucks. Not so many break downs for me, but I see this is a big issue for orhers. I wish my next truck be a glider, a Fitzgerald glider, well built for another 1.5 mil miles.
