Experience with new SCR engines?

I went to a Pete dealer today. Looked at some 389's and I really want one. Asked about gliders and the sales guy told me that "gliders won't bring in money in the future because its a kit truck". I know he was just wanting to sell me a new truck. I know gliders will be more valuable on resale later down the road. I'm glad that Fitzgerald's offers a Pete 389 glider with the Detroit 12.7 in it.

I hear ya, that's cool that you drive too

My part time driving has kept me out for 3 months this year one month at a time. The fuel mileage on the newer engines is getting higher and higher with every emissions level that the gov mandates and what the economy/fuel prices push. The one downside is that they are harder to work on and more expensive. The one good part is that the gov is mandating that OBD be on all trucks starting in 2013. This means that there will be larger access to cheaper diagnostic devices to help troubleshoot these problems.

 

That's very good. If third party companies can help diagnose problems then they can help eliminate them faster

The warranty on my factory rebuilt Detroit is tied to the motor and has nothing to do with the truck either. I could swap it out and put it in another truck with no problem. That Cat warranty you got is premium, no doubt.

The newer emission trucks are getting better. I don't think I have ever denied that. And there are some interesting advances going on like the OBD for one. But, Scotty in, I believe, the second Star Trek movie made a comment that seems so appropriate nowadays..... "The more complicated you make the plumbing, the easier it is to stop up the drain". In many ways, I love technological advances. But there are instances where technology can screw things up. Especially when these advances are government driven. It was not government driven when the OEM's decided to go to electronically controlled engines in the early 90's. It was to make engines more efficient. And it did the job. With Govt mandated stuff, We're not talking about an advance in technology that really improves things at the same or lower cost like personal computers. Look at what we can buy today for less money than an IBM PC back in the 80's. Technology has given us great products at lower costs than ever before. Except when it comes to government mandating junk on an engine. Especially when it is not really needed. Anyone who can clearly remember the 60's and early 70's will find it very hard to dispute that by the late 90's, the environment was in a lot better shape. And electronically controlled diesel engines (without EGR, SCR, and DPF) were substantially more efficient and cleaner than the old mechanical controlled ones, and it had nothing to do with any government mandate. But the government has to keep piling the stuff on, and we get to pay for it.

 

A lot of people seem to be having less problems with the emissions crap on the DD engines rather than the ISX. Cummins is still working a lot of stuff out, but DD is doing well. Not too many problems with our Cascadias in the fleet as far as Emissions go, I wish it was like back in the day, you could order any engine in any truck. Id love to see a pete 389 with a DD16 or a Mack CHU613 with a Cummins ISX.

I'd really liked to hear a DD15 or 16 thats been straight piped and had all the emissions deleted off of it. See what kind of MPG's you can squeeze out of that without the egr choking it down.

 

No kidding! I would also love to know how an unplugged DD15 would perform. Pablo-UA might be able to tell us??

They had those engines in Europe a while ago and they DID NOT have EGR but only SCR/DEF. Somewhere out there someone has to have done this or soon will. I am pretty sure Pablo-UA could give us some idea what it might be like.

Pablo-UA ...you there?

 

mercedes om471(dd15) never had versions without EGR .
it was designed for egr use from the start

 

I am not sure about that. The om472 (DD15) was introduced in in 2007 in Europe so why would it have had EGR ?

The DD15 is actually the OM 472 the DD13 is the 471. The DD15 or OM 472 was released in 2007. That is why I assumed it had SCR only and no EGR as that was not required under EURO 4 which I believe was the requirement at the time.

I am not in Europe right now, I am just one of the only Americans who knew long ago that the DD series motors were Mercedes NOT Detroit's like they tried to play them off in the beginning and still today. I know there was collaboration, yes, but it is a Mercedes motor built on Mercedes technology and is SO freaking FAR from and Series 60 technology that to try to have ever pawned it off as a "Detroit" was a joke and outright lie.
