Hilarious. A self-admitted Lawyer and Engineer, giving evidence under penalty of perjury that NAV makes a 13L engine. They've lost track of the truth. And what do the shareholders and customers think of these shenanigans? The Fat Lady is warming up in the wings, and they're trying to cancel the show entirely? Pages 36 and 37 are particularly enlightening, then check out the addendum at the very end.

I doubt that this POS would even get a hearing in Cook County.

EPA Revises SCR Guidance for ’10 Engines

(Transport Topics) In a move designed to bolster its defense in a federal lawsuit filed by Navistar, the U.S. EPA has revised its 2010 engine selective catalytic reduction guidance to remove a specific requirement limiting the hours and miles a truck can operate after its urea tank runs dry.

The revised document was sent to engine manufacturers earlier this month because some of the language in the agency’s February 2009 guidance “may have led to confusion regarding our intent that the document be used as guidance, rather than setting forth binding requirements,” Karl Simon, director of compliance and innovative strategies at EPA’s Office of Transportation and Air Quality, said in a Dec. 30 letter to manufacturers.

The earlier guidance, the focal point of Navistar’s federal lawsuit filed last year, specifically required engine performance to be severely degraded after the truck travels 2,000 miles or 40 hours after the tank is urea tank is empty.

The new guidance document eliminates the suggested limits on the hours and miles trucks can operate without sufficient levels of the urea solution before the trucks begin to lose power and eventually become inoperable.

MaxxForce 15 on schedule:

The latest engine from Navistar, the
MaxxForce 15, is on schedule according to the
company, due for launch in October.

Daniel Ustian, Navistar's chairman and COO, said the new engine's arrival would allow all
International trucks to be powered exclusively by Navistar engines.

MaxxForce 15 is a 15-liter engine based on the
Caterpillar US’07 C15 on-highway engine but with proprietary Navistar air handling, cooling and fuel injection systems and featuring massive exhaust gas
recirculation (MEGR). (Tweaked by MAN ?)

According to Ustian, it will be ready after only three years’ work, a short period compared with that taken, had Navistar designed the engine on its own engine.

But here's an interesting twist to Navistar's new Cat C15-based engine.

CAT C15 labeled “Unacceptable”:

Some of America’s largest fleets reported general acceptance of the 2007 generation of diesel engines during the annual meeting of the Technology & Maintenance Council in Tampa, FL. FedEx, which bought 2,369 tractors with Cummins ISX engines was satisfied. Schneider which bought 1,876 trucks with mostly DDC and Mercedes engines had seen 5% loss in mpg and frequent DPF regenerations.

Trans Am Trucking with 971 Caterpillar C15 had
seen dramatic repair cost increases, downtime
increasing by 125% and problems to find spare
parts. Their overall scorecard for the experience with the EPA’07 Caterpillar C15 - “Unacceptable!”
