TORONTO, Ont. — Clean air comes at a cost, and it involves the emissions-related changes to exhaust systems and engines, sometimes introducing added maintenance costs and reduced fuel economy in the process.
That’s led to one of the trucking industry’s worst-kept dirty secrets. Many truck owners are reprogramming electronic control modules to bypass SCR (selective catalytic reduction) systems, which reduce unwanted NOx by introducing diesel exhaust fluid to the combustion process.
JACKSON, TN — Navistar is disputing allegations that it didn’t thoroughly test MaxxForce EGR engines, in a case that saw former executive Jim Hebe testify that the company “did not test sh*t”, and a jury award a truck fleet US $30.8 million in damages.
NEW YORK — There’s now little doubt that the vast majority of engine manufacturers are gearing up for selective catalyst reduction (SCR) as the solution to meet the most stringent round of emission controls yet.
Selective catalytic reduction looks like the emissions sweepstakes winner.
LUXEMBOURG — The world’s first automotive ammonia sensor has been developed by Delphi Corp. The new technology will allow direct closed-loop control of the SCR (Selective Catalytic Reduction) systems used by an increasing number of diesel vehicles to reduce NOx.
WASHINGTON — Those engine manufacturers that have declared selective catalyst reduction (SCR) is the way to go in meeting the tough 2010 EPA engine emission requirements have been handed a blueprint to get the technology certified.
LOUISVILLE, Ky. — Not only will SCR technology provide engine makers with an option to meet stringent U.S. EPA rules in 2010, it also gives them an opportunity to finally agree on something.

By this time next year you’ll be putting diesel exhaust fluid into most of your new engines. Here’s what you need to know about the stuff.
NASHVILLE, Tenn. — Heavy-duty Cummins engines will not use selective catalytic reduction (SCR) to meet 2010 nitrous-oxide emissions limits like a handful of other engine makers. Nor will they need any other form of NOx aftertreatment.
GREENSBORO, N.C. — Volvo Trucks North America is now accepting orders for new EPA 2010-compliant trucks, with delivery starting later this year.
