DPF delete question

[NotSoFast]

Since I started plugging in my block heater on cold mornings, my truck hasn't gone into a regen. It totally loves starting out with a block temperature of 70 to 80 degrees F. That's even when it isn't getting much towing. Any engine will pollute more when cold. And as for the idea that the truck runs just as clean without the filter, it seems as though the filter wouldn't clog unless it was filtering out particulates. The DEF system is upstream from the DPF filter. That system reduces the NOx.

The DEF system is upstream from the DPF filter. That system reduces the NOx.

The SCR which uses DEF is after (downstream) of the DPF. It's located after to reduce soot fouling.
The DOC that is usually upstream or combined with the DPF.

Like I said, it’s all about what comes out the tailpipe. Not “tuning”. SMH

The scr allowed far more aggressive tuning vs the EGR only system that predated it allowing for more torque and power.

When comparing here we are talking scr vs EGR not a deleted truck.

As for the op. If you're already having problems with the DPF then the Cummins isn't the right engine for your needs. I love the diesel trucks but I only have one again because it was left to me. It's not something I have a use for now. I've considered trading it for a 6.4 so it fits my driving and towing needs but the truck has sentimental value.

I suspect you spend a lot of time driving at lower speeds than the highway. I have put over 200,000 miles on two 1500's with the 3.0 Ecodiesel engines (baby diesel) which in no way compares to the Cummins you operate. But, I have never in those 200,000 miles gotten a notice of my DPF getting loaded. I operate a lot of miles city driving and unless I'm on the highway I always drive in the Tow/Haul mode which changes shift points and other software programs to keep my RPM's at a range
that keeps my DPF clean. Just a suggestion.

Don;t let the engine idle,,that will plug up the dpf very quickly

Yea, so?

Our own government even knows this emissions crap is…well, crap. Hence why they outfit their own vehicles without it.

From the EPA website.

Exemptions from Diesel Engine Emission Standards​

General Exemptions​

Certain diesel engines are exempt from emissions standards based on specific criteria. These exemptions include:

• Engines under 24 horsepower: These smaller engines do not fall under Tier 4 regulations.
• Railway locomotives: Subject to separate EPA regulations.
• Marine vessels: Also regulated under different EPA standards.
• Underground mining equipment: Governed by the Mine Safety and Health Administration (MSHA).
• Hobby engines: Engines with a displacement of less than 50 cubic centimeters per cylinder.

Additional Exemptions​

• National security exemptions: Granted for engines used for national security purposes.
• Export exemptions: For engines intended for export, these are exempt without application.
• Pre-certification vehicles: Uncertified vehicles used for product development and testing may qualify for exemptions.

Compliance and Documentation​

Exempted engines may still require documentation to validate their status. Owners or manufacturers must maintain records and may need to provide information to demonstrate compliance with exemption criteria.
The best course of action is no delete. The Federal Government is not seeking criminal prosecution if you do so. It’s civil prosecution. States like Nevada went from civil prosecution to criminal prosecution for deletion. I’m sure other states like Washington, Oregon and California will follow Nevada’s example. You don’t want a criminal record and you don’t want to be in prison for deleting your truck.

DEF is not going away. And it’s not as troublesome to everyone as a few malcontents imply. My ‘24 Ram 2500 barely uses DEF and has given no troubles.

yet.

@ 8: mins you will learn DEF increases mpg and power output. Yep. True. (because engine mfr’s castrated engine-power to previously meet EPA req’s….. so DEF cured that issue. It’s a tail-chasing-dog thing.)
Enjoy the video, this guy’s funny. (accurate, but funny)

That is absolutely false. Increase MPG and power? Hilarious.

 

[Bramic71]

It’s illegal.

Can't be illegal, the Government does it.

 

[Snapper 60]

Well the only issue I can see apart from it being illegal and the EPA could cancel your vehicles registration plus if you don't have the parts to re install the DPF you'll have a very upset partner.
Try Rislone DPF cleaner available at you local Auto shop, I used this **** and WOW what a change better milage and definitely could feel the change in power, I never had a DPF light come on but just thought after 160,000kms I gave it a go very happy also put in a Turbo and EGR cleaner and the exhaust brake works like new, can't hurt!

 

[Bramic71]

Freedomworx does point out emergency responders may be deleted. You don't want a de-rate in an ambulance while rushing a critical patient.

I imagine LEOs wouldn't want this either in the very few that might be diesels (SWAT response vehicles, maybe?)

If the systems are so good and dependable, everyone should have them regardless of profession.

I have smelled so many rich running gas vehicles on cold mornings. I think all vehicles should be forced to run dpf, and scr systems if diesel owners are forced to.

Ford and a few other are introducing gas particulate filters = GPF on certain models and they have had them on cars in the EU for a few years now...
