I'll make it clear that I do not support the EPA, especially since I am a dairy farmer, however I do think people really need to understand the emissions systems better before bashing them. Too many just jump on the bandwagon with hate the EPA etc. Its like teasing the bully, hes gonna beat your ass the more you pick on him.
what i find funny is the hole dpf filter yeah it collects emmissions and holds them so u drive clean but when it regens then u just burn out everything in the filter so yeah while u drove 1000 miles clean as soon as u hit regen bam everything ur trying to keep in is out in the atmosphere yeah its BURNED out but u never see a emmission test done while the truck is regening then lets talk about clean air and see what really comes out
The DPF doesn't release anything. It holds all of the PM in it. When it goes into regen, it reduces the sizes of the particles and they all get collected and trapped into the media while other non pollutant products are expelled. There is always buildup left, and every regen builds more up.
Think of it this way. The soot coming out of your motor is like snow. It gets trapped and stacks up deep. Then you hit it with a flame and melt it down into water which takes up much less space. However after soo much snow, the bowl is filled with water and needs to be emptied.
Its a terrible analogie but I hope it makes some sense.
Haven't seen any mention or studies that detail the extra fuel that is burnt to perform the regen. Nor have I seen any studies on the extra polloution from fuel producers, to supply the extra fuel that is needlessly burnt.
Where are those studies Mr. EPA??
Heres the thing. The DPF removes over 90% of the PM. So you would need to burn a lot of extra fuel to even come close to having higher emissions than before the DPF.
On the grand scale I just don't see it either. Fuel is moved very efficiently as it is so adding a couple percent isn't going to offset the reductions in PM the DPF's generate.
If we skip the 07-10 era of all diesels, and fast forward to the newer ones with SCR. The fuel economy for the power that they have is actually pretty decent. Class 8 semis are now getting back into high 7s with 8mpgs in sight on some of them.
I work for a truck and equipment dealer as a Tech. Curious to me when a Dpf filter gets cleaned (which we dont do yet) the polution created when they get cleaned ! Were does that go MR. EPA ????????????????
It goes to a hazardous waste disposal site. aka landfill, but then it is trapped and not in the air.
yes i know and u are correct but like everything were u there to see the results of this 90% clean i sure wasnt im just saying they claim it 90% clean but i dont see how it can be 90% everytime espically if u use ur truck for like farming ect yeah mabey if all u did was run down the highway but if ur useing ur truck hard i dont see it being a clean burn everytime
Think of the DPF as an air filter. It filters 99% of the dirt and such out. it doesn't matter what you are doing with your truck, its a filter, its always filtering to a certain level. Thats they way the DPF works. There is a certain size that can pass through it and that size stays the same no matter what. The engine may burn cleaner or dirtier with your driving but the DPF just keeps filtering. That is why it is recommended to not idle the trucks.
what i think is even more ****ed up is, edge / h&s / whoever else has probably gave their mailing list and what products they sold to whoever to the EPA as well so that the EPA can go after the consumer and possibly lessen the impact on them (edge / h&s / whoever!)
Doesn't sound like they want to. In the article it said Edge had to offer to buy the products back. The EPA doesn't have the manpower right now to deal with thousands of individual cases. They just want the big fish with the big dollars.
I'm not looking forward to seeing how this will impact things like sled pulling and other off road events we all love
CARB tried to shut down the pulling circuit on the west coast once when someone from there went to a tractor pull for the first time. They responded with "you'll have to shut down NASCAR then". After some dispute, the pulls were resumed before the next weekend.
Face it. Pulling doesn't generate a ton of income for them if any. NASCAR on the other hand seems to draw every person out of the woodwork for whatever reason. Running 20-30 800hp motors for 500 miles is a little worse than running a pulling tractor or truck for 10-15 seconds.
Apparently we are the only ones that remember that e-mail from a while ago...
Clint... er I mean Mackin:rofl:
I almost forgot about that ordeal.
Where do they draw the line? Trust me. It sucks for all of us but what would happen if people started doing deletes on semis, farm and construction equipment? Then next thing you know we back to stage 1. Why should we be able to not run dpf and everyone else does?
Theres thousands of semis with delete kits installed. They are pricey to do. Generally you'll spend $5,000 to remove the DPF, EGR and get it tuned and running properly.
Some people are doing it to their tractors as well.
So you guys blame EPA ( which I cannot stand ) for this and go on to place the blame on other vendors. H&S was confronted by EPA after their stupid video of an LML blowing big time smoke on a public hyway. They were told to stop and their answer was FU. Why would the other vendors do this? EPA doesn't make deals.
I have pm's from H&S calling me the biggest asshole that ever lived when I told them they should not have made that LML video public. They said I was a paranoid MF. They called me stupid. I told them that they compromised the whole diesel industry and they told me to FO.
Now I hope they burn in hell.
I've never really cared for H&S as they seemed to become popular for the sheer fact they had an easy DPF delete system with tunes that made smoke.
Not many fans in those bleachers that I count compared to the NRHA racing today. I'm getting a Camaro and making a runner from it because the diesel problem makers are ruining the diesel format into an EPA trap.
I hate breathing diesel smoke but its a little easier on the eyes and nostrils than Nitro is.
oh I see what you mean, I still think in LB7 lol. I know Rob has been tuning a shop truck with the DPF still on. I could see a track only Y pipe that you can undo for off road use only. Or maybe some sort of propane injection for the regen.
Diesel fuel works good for the regen. You don't want to have to drag around a propane tank too.
The technology for the regen setups is getting better.
Volvo gets flamed a lot for their off road system due to its complexity, but it works damn good and reduces the time between off the machine cleanings. They use a high pressure blower along with the diesel to generate a flamethrower. Looks just like an afterburner on a jet.
In the meantime, enjoy the LML for what it is....a good towing truck.
Exactly. I wouldn't want to give our LML any more power than it has. we pull big trailers, but its still plenty for a pickup. I mean we generally gross 36k or so but have gone higher to over 40k. LML is rated at 397 and 765. Our Kenworth for hauling milk @ 80,000lbs has a C13 ACERT rated at 430hp and 1650tq. Now that were pulling some 9% grades though I think its time for the Euro file (500hp). Granted yea its the torque that counts, and really makes that thing fun to drive. All of the power comes on at around 1250 and you run it up to 1550 or so. The ACERT's run more on the Miller cycle versus the Otto cycle, they hold the intake valve open longer to let cylinder pressure out, but then use the twin turbos to boost early and create pressure fast. That motor makes 50psi+ where our other 435 N14 Cummins makes 30 and the Detroit does 25 or so.
Look at our most powerful row crop tractor that pulls manure down the road at 120,000 or so. 350hp and 900tq IIRC.
The LML has a lot of power in my opinion. Its very laggy if you do not adapt to the way it likes to be driven, but it has plenty of power, and without traction control would really be bad on the road.
Maybe I am getting old though.
