    I don't know 100% the details of how the EGR systems work on trucks, but I do know when I drove the EGR trucks, they had their problems. In a year, I had to be towed twice and nearly had to be towed a third time. Once I sat 10 hours waiting for a worn-out system to do a parked regen, and then the regen only lasted a a few days and it wanted it again. Then there are the stories of guys needing to be towed to dealers or terminals, where they sat for days and lost hundreds, if not thousands, waiting on repairs. Then the cost of the repair set them back some more thousand-dollar bills. There must be a better way. I've heard in either 21 or 22, the glider kit loophole will be closed, meaning all trucks will have the EGR and regen system. I've wondered if any of you owner operators have considered putting dual canisters on your systems, with one being the primary and one being the back-up? Equip it with a gate and a wiring set up to transfer from the primary to the secondary, and the regen problems leading to tows and long down time should be solved.

    That system is a complete marketing joke but they'll sell them I'm sure.

    They are pretty reliable today I'm driving 2017 truck 289,000 miles and no emission trouble yet. They also talk about cleaning the EGR system at 250,000 if you really want to help avoid any problems. They have that foam that pumps into EGR and cleans everything. Plus the Dorothy look like good thing if you have your own truck.

    You do know that the regen and the egr problems are two separate issues?

    Dual dpf will not solve a thing.
    Oxbow, pushbroom and AModelCat Thank this.

    So as long as you take care of them they run how they are supposed I have about 8 trucks running around highway is 700 k and lowest at 460k not one of them has been stuck on the road once as long as you properly maintain it and I don’t mean just take out and bake the filters there is a lot more to that system than that. That being said. I know and have seen in Europe they do make a valve to switch between straight pipe and emissions as needed from what I know it leaves just enough exhaust going to the filters to not set off any check engines and the rest goes to a straight pipe. Never installed one Had a few customers bring one in and I told them I won’t put it on so don’t know how it works.
    Oxbow and Misesian Thank this.

    Proper maintenance, don’t idle and it will be fine. The new ones are much better. Anything 2015 and later is doing pretty darn good. 2010 EPA motors are ok but the idle hours will kill them. Idling doesn’t hurt the engine but it’s the EGR circuit under the hood that takes a big hit when idling. If it’s your truck I recommend an oil bypass system. That will help greatly when it has high miles keeping the trash out of the oil. They’ve reduced EGR flow a lot and cleaned up the combustion but you still get a fair amount of soot in the oil.
    Rounded_nut Thanks this.

    The biggest thing with idling is it doesn't make heat in the exhaust. I don't believe idling neccessairly plugs the DPF, it just doesn't produce the heat needed to keep the soot levels down. See, people assume that a DPF regen is used to burn out the collected soot. While that is true, the DPF acts like a catalytic converter. Under high heat, the soot is catalyzed and is cleared out of the DPF. So when you're pulling hard and working that engine you're actually helping to keep that DPF cleaned without running a regen.
    Oxbow Thanks this.
