TRUCKMAKERS' ENGINES DEBATE * WORLDWIDE - SCR or EGR ?
* Sweden - Volvo is the first to publicly announce a price tag for a 2010 SCR system
Linkedin (USA)/"World of Trucks" group, by Jim Mele -10 March 2009: -- ("Volvo: SCR will cost $9,600": USA -Fleet Owner -March 03, 2009)... Do you expect the other OEMs to be in the same range? What about Navistar and its "Advanced EGR" approach?
* USA - Navistar does seem to have a lot of questions to answer
Linkedin/"World of Trucks" group, by Oliver Dixon (London,UK) -10 March 2009: -- Taking MAN's Euro V engine and making it Euro VI compliant (EPA 07 to EPA 10 in all but name) seems like a pretty neat trick, especially given that MAN has said no can do without a very significant increase in diesel consumption. Hence MAN's embracing of SCR for Euro VI, and the surely reasonable observation that NAV's achievement of an EGR-based MAN-designed engine that is both MPG-neutral and EPA 10 / Euro VI compliant has all the appearance of a deal brokered by Mephastophilis. Denmark and noxious odours come to mind... If we are to believe NAV's assertions, then we have to believe that an awful lot of people - including those who designed and engineered the Maxxforce engine in the first place - have got things very wrong, and NAV has got things very right. Will NAV now resell MAN's engine back to MAN for Euro VI? This has the potential for much merriment and high comedy. Followed by red faces and the large servings of humble pie.
