WASHINGTON, D.C. — Clean diesel trucks with diesel particulate filters (DPFs) built after 2006 now comprise 28% of all trucks on US roads, according to a new report from R.L. Polk and Company for the Diesel Technology Forum.
Of 8.6 million trucks registered in the US, 2.5 million are equipped with clean diesel engines with DPFs, the groups announced.
“The fact that more than 28% of all trucks on US roads today are new technology diesel engines with near zero emissions is significant for the environment and the trucking industry,” said Allen Schaeffer, executive director of the Diesel Technology Forum. “More than 95% of all heavy-duty trucks are diesel-powered, as are a majority of medium-duty trucks. Diesel power is the driving force today of goods movement by truck in our economy and they are continuing to play a central role of the United States’ new effort to reduce fuel consumption and lower greenhouse gas emissions (GHG) in the coming years.”
He added: “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.”
Schaeffer credited more efficient engines, cleaner diesel fuel and emissions control technologies for reducing the pollution from heavy trucks since 2007.
“The new clean diesel technology has reduced emissions from heavy-duty diesel trucks and buses by 99% for nitrogen oxides (NOx) and 98% for particulate emissions,” he said. “What makes the new diesel technology even more remarkable is model year 2010 and later trucks are experiencing an average of 3-5% improvement in fuel economy. Additional fuel-saving strategies are being developed to improve engine efficiency, vehicle aerodynamics and expanded application of hybrid technology.”
Schaeffer noted diesel power moves more than 82% of all cargo in the US, and 90% worldwide.
