Opinion * USA - Engine Makers’ Rivalry Reaches Heated Level
Louisville,KY,USA -Transport Topics, by Howard S. Abramson -8 April 2010: -- This year’s version of the Mid-America Trucking Show here cast a bright light on the ongoing fractious debate over which engine technology makes the most sense for fleets that operate heavy-duty trucks in North America... While it’s not unusual for competitors to praise their products to the sky, it is quite unusual for them to denigrate those of their rivals... DTNA, along with its other competitors in the engine market — Paccar Inc., Volvo AB’s North American unit and Cummins Inc. — have chosen selective catalytic reduction to meet the new federal emissions rules that govern 2010-model trucks and later... Andreas Renschler, who runs Daimler’s global commercial vehicle unit, which includes DTNA and its Freightliner and Western Star brands, told reporters: “We never gambled” in choosing a technology path. He said, SCR is “the most fuel-efficient choice. We made a very severe decision a long time ago and there is no debate any longer that SCR works best”... Navistar, on the other hand, has chosen to use an advanced version of exhaust gas recirculation — the technology of choice for all the major players in meeting emissions rules from 2002 through 2009 — to accomplish the lower levels permitted by the new standard. Ustian and Navistar’s other managers said EGR was simpler, lighter and well proven, and it won’t require the driver to maintain an adequate supply of the diesel exhaust fluid necessary to make SCR work... While it’s impossible to predict who will win this argument, as usual, in the end the market will cast the votes that count...Labels: EGR vs SCR
