More than 28 percent of all trucks registered in the U.S. – 2.5 million of 8.6 million trucks - are now equipped with advanced, new technology clean diesel engines, according to new data compiled by R.L. Polk and Company for the Diesel Technology Forum (DTF). The Polk data includes registration information on Class 3-8 trucks from 2007 through 2012 in all 50 states and the District of Columbia. Beginning in 2007, all heavy duty diesel trucks sold had to meet particulate emissions levels of 0.01 grams per brake horse-power hour (g/HP-hr) - a level near zero.

Regionally, the Midwest (31 percent) has the highest percent of new diesel trucks, followed by the South (29.8 percent), the Northeast (29.1 percent), and the West (26 percent).

New Technology Diesel Engines & Fuel Have Reduced NOx By 99% & PM By 98%

“Emissions from today’s diesel trucks and buses are near zero thanks to more efficient engines, more effective emissions control technology and the nationwide availability of ultra-low sulfur diesel fuel. The new clean diesel technology has reduced emissions from heavy-duty diesel trucks and buses by 99 percent for nitrogen oxides (NOx) and 98 percent for particulate emissions.

“What makes the new diesel technology even more remarkable is model year 2010 and later trucks are experiencing an average of three to five percent improvement in fuel economy. Additional fuel-saving strategies are being developed to improve engine efficiency, vehicle aerodynamics and expanded application of hybrid technology.

“In addition, new diesel technology and ultra-low sulfur diesel are benefitting many of the older diesel trucks built before 2007.  Through the use of retrofit upgrades, older diesel engines can improve their performance and reduce key emissions by up to 90 percent,” Schaeffer said.
