Well if you don't feel like your diesels are stupid expensive now they're going to be. 300k warranty..... I gotta admit it's pretty crafty on the government's part. Eliminate so many of those people that just delete their trucks cause they're warranties up and they have a issue.

I heard they threw gasses in on the particular filters too that's gonna be nice.

 

[2004LB7]

I'm going to guess a minimum $10k increase just from the warranty alone. The rest is going to add another $10k+ so it wouldn't be unexpected to have the prices go up by $20k

Hopefully the new administration can put the brakes on these changes and DOGE can neuter the agency so they don't just do it all over again in 2028

It doesn't seem that hard. Retard timing 20 degrees, run the EGR wide open. Maybe have one of those EGR filters that FASS is making. Have to change it every other oil change.

Add a large alternator for your High Voltage Soot burning coil. 30 gallon DEF tank since the SCR is going to be working over time. I imagine the truck is going to be going into Regen quite often. Hopefully the truck manages to get 10 MPG.

In all seriousness its kinda crazy these trucks will be putting out less PM than gasoline vehicles.

How about get rid of the dpf and EGR, tune for optimal burn, rather than feeding the engine it's exhaust purposely creating an incomplete burn and more soot, and if you MUST 'treat something ' , have a big scr setup for the nox and feed it horse piss measured in gallons per mile....

That's kind of been the goal all along, trust me these manufacturers don't run equipment they don't want to. Problem is that the "optimal burn" creates quite the Nox, and EGR slows the burn to combat this. At one time Cummins was ready to run only SCR, no DPF, but similar to the ATF the EPA likes to move the goal post

I agree. It seems counter productive to burn more fuel to "reduce" emissions.

The only emissions equipment I can see value in is the SCR or the "CAT" equivalent to reduce the stink diesel engines produce. Some deleted are so strong it makes your eyes water.

I feel exactly the opposite.. old non emissions (or deleted) diesels smell like perfume compared to EGR/doc/dpf/scr treated diesels... Just EGR and doc make my eyes and nose burn, add in dpf and it's worse...

Yeah, I'm not sure why some do it and some don't. Can't be all emissions components because my LMM will smell sometimes. With or without the DPF in place. DOC installed. So can't be that.

My LLY doesn't seem to have that problem. Has EGR and DOC.

Maybe it's mostly effected by tuning. Might have to do some testing on my LLY with adjusting the timing at idle to see if I can get that smell. High MPa/High timing, High MPa/Low timing, Low MPa/High timing, Low MPa/Low Timing, EGR on/off, etc. unless someone else has any ideas on what it is

You forget, carbon is bad for a carbon based world

 

[Mikey52]

The quality of diesel can have an effect on the watering and smell.

Id really love to sit and figure out the actual gain from implementing these systems. I know one can argue less NOx is good, but when the process to achieve that on the SCR side basically creates an entire new industry of manufacturing, shipping, and disposing (plastic jugs) how far ahead is it really in the end?

Same could be said for the temperamental DPF systems, that's another whole industry of parts, shipping and disposal.

IMO gains/losses are obvious. Gains being in the fuel system and application.

I've heard the early L5P would pull mid upper 20s and Regen every 800-1000 miles then GM did a software update after, it regens every ~400 miles regardless DPF/SRC filter level and might see 20 mpg afterwards.
Look into the CAT/EPA lawsuit over EGRs and ultimately why they got out of the OTR engine industry
The 567 Pete I drive with a 500hp X15 Cummins barely gets better mpg than my buddy's built 700hp C15 cat in a W9, like I avg 6 doing pickup and delivery to his 5.5mpg hauling open top beam wagons that don't pull straight and usually rolling 15-20k heavier.
The math doesn't make sense

The MPG dor diesel vehicles as been pretty stagnant for the last several decades. While gasoline vehicles see steady improvements and now set close to or even exceed diesel in some aspects.

Since this monstrosity of an emissions system is really only effecting people who drive diesel. There is not enough people to push back hard enough for the government to pay attention or care. But if these new regulations for a GPF and possibly other equipment go into the gasoline vehicles then you'll now have millions more being impacted by it. If new vehicles are returning 5 mpg less than their previous models, people may be reluctant to "upgrade". And when they are breaking down more often or are getting stranded out in the middle of nowhere there is going to be more push back and possibly a rolling back of these regulations. Or at least one can hope

Its all to push people into EVs.....

Very true but they have also been a lot more innovations. More turbo use, smaller engines, VVT, Direct Injection, etc

At its core the Duramax hasn’t changed a whole lot. Is it unreasonable to think that if you slapped an after treatment system, better flowing heads and changed the logic in the ECU of a LBZ it would be able to perform similar to an L5P. That engine is almost 20 years old.

Think about the jump from the 6.5 to the LB7.
That’s quite the difference in technology. I think we need something similar now.

I honestly have nothing against EV. They will be great once the technology allows them to. But forcing something on the world that isn’t viable just doesn’t make sense. Break through as in battery tech will eventually make them make more sense, but even then at the end of the day the grid has to be able to handle it. And we are far from that.

If only we could have a movie grade power source that could power our EVs for a minimum of 20 years before recharge or replacement. Going to have to be some major improvements in battery technology before they can replace the ICE

That's my thought on EVs. Sure, there are some use cases where they're great. For my wife's daily commute, an EV would be great. But if you take long road trips, that's where things change, no matter what the diehard EV fans say. I've made two trips from MO to SC in my 3.0TT CT6, stopping once for food fuel and bathroom in GA and rolling into my destination with fuel to spare. An EV would have SUCKED for such a trip since at this time, you can't stuff 400+ miles of range into a battery pack in 20 minutes or less. Maybe some day EVs will truly be able to fully and equally (or better) replace gas/diesel. But not today. And that sort of shift has to happen organically, not get stuffed down our throats.

Exactly. I've seen a few studies on the cost to own an EV and in order to make sense.ypu have to change at home for something like 10¢ a KW to break even with gasoline prices. That doesn't even take into account the increased cost to purchase one. If you have to use a charging station then it's more expensive and takes longer.

So really only good for short trips and charging from home. Your probably better off renting a gas car for long trips then using an EV. I also thought I remember something about one or more of those car rental places offloading their EVs as they didn't pan out and was costing too much and repairs where a nightmare. Says something when you know if they where profitable and mature technology the rental companies would convert instantly. But haven't

If EV made sense on a capitalist front.. there would be substantial more EV taxis in major metros. Unfortunately they don't even come close to 25% of the taxis
