CARB admits DPFs may “impact engine performance and eventually cause engine damage”

The Alliance for California Business, a group the represents California trucking and farming businesses, recently won a small battle in the fight against the California Air Resources Board (CARB).

Since 2013, the group has tried to get lawmakers to roll back CARB’s Diesel Particular Filter (DPF)
mandate by proving that the filters are neither safe nor mechanically reliable.

In a recent public notice, CARB has acknowledged that trapped soot in DPFs may indeed cause engine damage. The staff report, published in March 2016, states the following:

“… trapped soot in the wall-flow DPF builds up over time, increasing the backpressure on the engine as it continues to operate. Operating the engine at excessive backpressure for extended periods will impact engine performance and eventually cause engine damage.”

This information was not publicly available in 2015, when a Glenn County Superior Court judge denied a preliminary injunction against the DPF Mandate. The group hopes to use the new information to convince lawmakers to take their side in the fight against CARB.

“It is time for CARB to do the right thing: issue a recall on all DPFs until they are proven safe and mechanically reliable,” the Alliance for California Business said.

Well, well, well...

 

I have given up on California. Would be nice for everyone if they came to their senses, but I'm done with them.

 

If they do that, it would be like admitting they were wrong.

We can't have that now, can we?

 

CARB will never admit that its wrong.....

 

This has been posted last month on here already.

 

They will never admit they are wrong,instead they will argue that with proper care the equipment will performe like is intended,the sad part is that a few O/O will tell you the same ,yeah like that famous engineer from TN.
If any of you do some research on how C.A.R.B came about ,you would understand that i was nothing but political motives
I stop going in to CA untill my 2007 trailer was allow to do so, i will not take any more load in or out . So far they havent been to serious about enforcement but ive heard of drivers getting popped with up to $1500 fines ,it is my opinion that this is all a SCAM .The state of CA gave grants to Companies to upgrade their fleets .at first a lot of those old trucks went South of the border, to companies that move freight into US ,turns out they were exempt from compliance for while i dont know about now.
In the other hand the main issue is that it is true D.P.F,D.E.F,S.C.R,V.G.T. and E.G.R. Engines Are P.O.S they wont last as long fuel economy is ####ty @ best and preventive maintanance is costly. Im just ranting to let some steam off i guess .The truth is tha CARB and EPA are here to stay .I've never heard of a Goverment Office or program clossing or scaling back ,they jus dont Care about our strugle .All they care about is special interest groups
Just recently i read that EPA wants to increase regulation before current Administration is out .Soooo GO LAME DUCK
Get with the program fellas
Sorry about this nonsence

 

Everyone is entitled to there own personal opinion. I live in this state and had the retrofit done. No issues and had it one year ago. Yes, CARB and ARB are here to stay and will eventually end up all across the country. Once the government gets involved, there here to stay, just like the ELOGS, OOIDA, CTA, Unions can file for lawsuits and have there here say in court, the only thing they get is an extension but eventually the government wins.

 

Last week, crawling in Cali traffic. from Napa to 80. I could smell smoke, i thought was the brakes. Then i could see the wind blowing a light smoke, brakes should be cooling down since i'm not really going anywhere so i thought it was a car behind me smoking the blues. But then, we started rolling about 10 mph and i could see smoke coming from under the truck skirts, getting heavier. NOW i'm thinking something is on fire. But when i pull over, and the truck is running with fan on because of the a/c. i couldn't find a darn thing smoking. Or smelling. I shut the truck off, open the hood. NOTHING. So i go back down the road and all was good.

Only thing i can think of was the DPF. Truck is almost a year old. If that's what it was, it would be my first experience of smoke.

 

I saw overcooked cummins myself. The backpressure caused by dpf will boil pistons. The result is overhaul and it had only 530k miles. Sad

 

I was working on a trailer for a guy and his started the regen procedure. He had smoke escaping from the air cleaners as well as from under the hood while this was going on. I asked him if that was normal, he said it happens every time it does a parked regen.
