Navistar International Corp. won’t apply SCR to its 15-litre MaxxForce engine and will instead lean on Cummins Inc. for its high-horsepower requirements, Jim Hebe, senior vice-president of North American sales operations confirmed during a press briefing in Salt Lake City.
Truck News reported that it’s the first official confirmation that the company won’t pursue its own 15L engine once it uses up its remaining emissions credits and can no longer pay non-conformance penalties for engines that don’t meet EPA2010 emissions standards.
“Our intention is to continue to build them as long as we can and then phase into the Cummins ISX15,” Hebe told a small gathering of truck journalists here today. “It’s a shame, it’s a great engine.”
Hebe said anticipated demand for the 15-litre MaxxForce would not support the cost of further developing the engine and applying SCR exhaust aftertreatment to it. International will focus on its higher volume MaxxForce 13 engine, which will combine selective catalytic reduction (SCR) exhaust aftertreatment with Navistar’s in-cylinder solution to form what it has dubbed In-Cylinder Technology Plus (ICT+).
Officials indicated Navistar is already building International trucks with Cummins engines and that the existing Memorandum of Understanding between the two companies will soon become an official supply agreement.
Hebe provided some insight into what went wrong with Navistar’s EGR-only emissions strategy. He still believes pursuing a non-SCR emissions solution was the right call, however he admitted it was a mistake for the company to put all its eggs in one basket.
“Two decisions were made in this company in August 2008,” Hebe said. “One was to go EGR and the other was to go it alone. The decision to go with EGR was not the wrong decision, but the decision to go it alone was the wrong decision. What really, in the end, created the biggest issue was not EGR, it was that we ran out of time and we ran out of credits. If we had stuck with a partner in the engine business, we would have had more time to develop our in-cylinder solution and probably at the end of the day, we would’ve gotten that. That’s water over the dam now.”
Navistar has been hosting more than 700 dealer reps at its Vocational Boot Camp in Salt Lake City over the past few weeks, and Hebe said dealers are clearly more comfortable with the company’s current path.
