Improving America’s Infrastructure with the Most Advanced and Cleanest Equipment

Week of May 16th-23rd Focuses on U.S. Infrastructure and Public Works Networks

Washington, D.C. – This week, hundreds of organizations are honoring the past accomplishments and future growth of America’s national infrastructure during Infrastructure Week and National Public Works Week.  With diesel equipment serving as the overwhelming power source for past and future infrastructure growth, Diesel Technology Form Executive Director Allen Schaeffer issued the following statement about how construction and off-road equipment is now cleaner and more efficient than ever before.

“Emissions from New Clean Diesel Equipment Have Been Reduced to Near Zero Levels”

“Infrastructure is the back bone of the U.S. economy and our global competitiveness, and it’s vital we start reinvesting in its future.  It’s been over 40 years since most portions of the Interstate Highways System were completed.  Since then the materials and methods for safe road building and design have advanced by leaps and bounds.

“But one of the biggest advancements comes from the new generation of construction machines and equipment that do the work.  Emissions from mission-critical new clean diesel equipment have now been reduced to near zero levels which is providing major environmental benefits throughout the country.

“The end result is that these technologies enable infrastructure projects to be built faster, using less fuel, and generating a fraction of the emissions from even a decade ago.  And this is especially important to the people living and working in the communities around these job sites.

Tier 4 Engines Are the Cleanest in History

“From bulldozers, to excavators and motor graders, the latest generation of clean diesel technologies that meet Tier 4 emissions standards can now build and improve our infrastructure while also significantly reducing emissions at work sites.  These Tier 4 compliant engines reflect the most recent emissions standards for off-road equipment established by the U.S. Environmental Protection Agency (EPA) for equipment manufactured since 2014. 

“Depending on the horsepower range, emissions of particulate matter (soot) and oxides of nitrogen (NOx) have been reduced by more than 90 percent.

“Whether we’re talking about moving massive amounts of dirt, milling pavement, pouring concrete, trenching for cables, or laying pipe for new clean water systems, or massive cranes used for building bridges, the jobs all come back to diesel power.

“Manufacturers have taken efficiency, fuel savings and lower emissions well beyond the design of the engine to include efficiency improvement in the overall machine.  Advanced engine designs, hybrid capabilities and energy storage technologies, and even advanced telematics systems, GPS and integrated work site control systems are now deployed in new equipment and combine to yield substantial fuel savings and emission reductions.

“The adoption of ultra-low sulfur diesel fuel in 2006 set in motion the path to clean diesel technology, and increasingly in the future the use of biodiesel and renewable diesel fuels will provide additional options for lowering emissions and reducing carbon footprints.”

Examples of the latest technologies integrated into new Tier 4 engine and equipment include:
