That would work for sure AND eliminate the extra fuel line to the DPF. That makes sense for sure. B.
Apparently...I just found out yesterday...Branson is using a non-regenerating DPF/DOC. The good news is that you have no regen cycle to worry about. The bad news is that once it is plugged, you have to buy a new one, or much more likely a reman or a re-cleaned unit. This DPF/DOC is a very robust unit with a lot of platinum in it allowing it to go a long time and simply not need cleaning. How long? To pass testing for EPA they had to run 2000 hours and still be entirely effective and they had no problem passing that test. If that test is an indicator of the real world life of the unit, it will be years and years down the road before you need it cleaned. My guess is that there will be remans for $500 or less, but I expect nobody has remanufactured one yet. If you needed one right now, it would be costly, however it would also be under warranty. Unless some scoundrel stole it for the $1500 worth of platinum in it...that would not be warranty, it would be insurance I suppose.
Another interesting fact is that this new engine is basically the old engine, it is not a CRD. The engine management system does not really talk to the DPF. If the DPF/DOC were removed, the engine would not know it. I know on my Ford F350 diesel, if a person removed the DPF the truck would not operate without illegal tuning. PLEASE understand, I do not condone removing the DPF or changing any emission related equipment. I like clean air and I understand tinkering with emission stuff is not legal...so don't do it. The purpose of my comments is just so you can better understand Branson's strategy. They used the same engine with minor mods and put on a super duper DPF/DOC. Other brands use a less super duper DPF/DOC (less precious metals) and keep them working by cleaning them often. Other brands use no DPF and get most of the clean air by the use of CRD controls and just a DOC. There are many ways to skin this cat.
Do you think the regen on these small tractors is just wot (wide open throttle)? Not an actual regen? I do know the bransons don't have a fuel line going to the dpf just 2 pressure sensors and temp sensor. Any thoughts on that? Do you think 800-1000 hrs is short life? I have a 3500 ram with the cummins 6.7 and have 75000 miles on her and haven't replaced the dpf. Some say you'll only get 75000 miles out of them on the ram since no Urea. I don't know, I have only seen my light on once saying it needs to regen. I thought kioti had urea? Maybe not.
