Learning Session: Getting Ready for Tier 4 Emissions Laws

Challenger has taken the challenge of reducing emissions almost to zero seriously and is ready to meet the Tier 4 EPA regulations that go into effect in January 2011. It is relying on e3 techology, using diesel exhaust fluid or DEF (32.5% urea and 67.5% distilled water). Mixed with diesel, it cools the engine, and NOx emissions break down into nitrogen gas and water. It reduces carbon dioxide emissions as well.
"Major on-road truck companies already have adopted this technology,” Challenger's Jason Hoult told attendees at the Top Producer Seminar. "Major truck stops are committed or you will be able to have it delivered to your location.”
Side benefits include better efficiency (more miles per gallon), a lighter, more efficient cooling package and longer oil change intervals, he says.
