FireHead Posted January 21, 2009 Report Share Posted January 21, 2009 Main problem right there. Regen needs to have the engine worked hard and build heat...which idling will not do at all. Go out and haul on the engines once and awhile to get things burning. And yea usually when trucks go into Regen mode you loose power. Few people that drive Volvo's recommend pulling over once the light warns you Regen is about to start. This way you can sit on the side of the road/truck stop and let it do it's thing. The other thing that might help out is idling up the engines while they sit there, 1200RPM or higher if need be. Mark, How come you and other companies are going with SCR After Treatment, while Navi and Cummins are going for EGR Design, is one better than the other? Cummins is not going for the high and low temp. EGR desgin + cashing in emissions credits................ they could not meet emissions reulations so you will see them with SCR systems across the their entire line. Navistar still has not produced a system that will certify with the EPA with their non-SCR setup. So far, they are all talk and don't have anything in trucks. We'll see what their high percentage EGR system + emissioins credits will get them. Note also the PACCAR (Kenworth and Pete) house brand (Daff or Foden designed) engines will also be rocking SCR systems for 2010. The SCR systems increase fuel economy and lower operating costs greatly (2% DEF per gallon of diesel) since you no longer have to rund you exhaust after treatment at high temp. to reduce NOx.

FireHead Posted January 21, 2009 Report Share Posted January 21, 2009 This is very true. The problem we are having is that for most of our trucks they will idle for 80% of their life. They spend most of their time under the power lines with a guy up in the air working out of the bucket. What engines do you guys build? I hear cat is getting out of the on raod engines for the most part in the big trucks. I work for Detroit Diesel (owned by Daimler). CAT is getting out of the over-the-road NAFTA engine business at the end of 2009 (only 1.5% of their total global business). Their EPA07 heavy duty stuff is crap anyway......... there's a spark plug in the exhaust and the aftertreatment is one raging breakdown after another.

Makes sense if SCR systems up economy and lower operating costs. Is there anything like a Regen cycle with this system, or will trucks be able to keep on driving without lose of power? Are these Emission Standards that are hard to beat set for 2010, or later? Edited January 21, 2009 by Dinner Quote Link to comment Share on other sites More sharing options...

You still have a regen. cycle, but it's at a lower temperature, which gives you many more thermal management options. You may still have a bit of a derate in certain situations with this system. The EPA10 standards are not too terribly hard to beat with an SCR system. The OBD system (similar to OBD II in cars) is pretty tough right now. EPA14 will be much tougher when they start requiring CO and CO2 levels to be regulated. :geek: Quote Link to comment Share on other sites More sharing options...
