Navistar to ditch EGR in favor of SCR

I know they did more, but painting a yellow engine black was not going to cure the egr issues that brought cat to the brink! Sure if the 08 cats had def and the dpf and the extra years theh would have been as great as the 07s!!! But it was not ready for prime time!

 

These new emission junk is killing the trucking industry. Maybe the EPA wants all the little guys to fail so its just the big companies running it all.

 

It's funny that the engine that was mentioned was the 13 which cat has nothing to do with, not the 15. Also cat has an industrial engine that comes within a minuscule amount of meeting the truck emmissions, with some tweaking it could be made to meet truck emmissions. Don't throw caterpillar under the bus because navistar screwed the pooch.

 

This goes great with the increasing popularity of auto transmissions and everything else to make the driver have to do as little as possible. Maybe eventually they'll come up with a way to phase the driver out.

 

Cat belongs under the bus. After their 07 screw Job. They put out that pos and then bailed . Can't blame
Navistar for that one can they!

 

That's not what this thread is about. If companies were given the proper time to truely test the emmision equipment there would be a more reliable product, but this changing requirements every three too four year doesn't leave much time to build things that work. Every company was rushed between 04 - 10, and quite frankly none of the 07 emmission engines are tht great cause they were focused on the 2010 requirements. Honestly cats best bet would have been to get out in 07. I wouldn't have put that much effort forth either when in 3 years it would be obsolete. Looking at their profits I'm sure they regret not getting out sooner than they did.

 

I asked how this might effect the cat 660 truck, a Navistar clone. And now 5 years later cat has another emissions pos on there hands. They obviously have not learned a #### thing!

 

You really don't understand how that partnership works do you, cat supplied the C15 block and rotating assembly to navistar, possibly the head, as they were already working on a HPCR system for their industrial engine, and the emmisions were left to navistar, most likey in exchange for building the 660 with rebadged MF11 and MF13 in them, still not a cat engine, the telltale sign is the CGI block.

Here is my thing, unless you are located in a ####### state that mandates truck age you were not forced to buy a brand new truck, so why did you knowing that all problems stem from emmision equipment that is mandated on all new trucks, when a slightly older more reliable truck would have sufficed.
