According to data compiled for the Diesel Technology Forum (DTF), more than 28 percent of all trucks registered in the United States are now equipped with EPA’07 compliant advanced technology clean diesel engines, including compliant diesel particulate filters.
The data, compiled by R.L. Polk and Company, includes registration information on 8.6 million trucks in classes 3-8, from 2007 through 2012 in all 50 states and the District of Columbia.
“The fact that more than 28 percent of all trucks on U.S. roads today are new technology diesel engines with near zero emissions is significant for the environment and the trucking industry,” Allen Schaeffer, the Executive Director of the Diesel Technology Forum, says of the fleet’s challenge to meet particulate emissions levels of 0.01 grams per brake horse-power hour – a level near zero. “More than 95 percent of all heavy-duty trucks are diesel-powered, as are a majority of medium-duty trucks. These increasing penetration rates are a reflection of the confidence that truckers have in the new technology diesel engines, particularly during the last few years which have been a recessionary period with lower demand for trucking services.”
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).
Top 10 New Technology Diesel Trucks States by 2012
1) Texas 286,045
2) Indiana 169,509
3) California 168,965
4) Illinois 115,125
5) Pennsylvania 113,020
6) New York 97,073
7) Florida 91,672
8) Ohio 88,671
9) North Carolina 72,286
10) Georgia 71,136
“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,” Schaeffer adds. “Additional fuel-saving strategies are being developed to improve engine efficiency, vehicle aerodynamics and expanded application of hybrid technology.”
And benefits aren’t limited to new equipment.
“New diesel technology and ultra-low sulfur diesel are benefitting many of the older diesel trucks built before 2007,” Schaeffer says. “Through the use of retrofit upgrades, older diesel engines can improve their performance and reduce key emissions by up to 90 percent.”
