About Clean Diesel

Construction

Because of diesel's unmatched and unique combination of power, performance, reliability, fuel efficiency and now low emissions, it is the technology of choice and the workhorse of the nation's construction sector, powering more than three-fourths of all heavy construction equipment.


Because of diesel's unmatched and unique combination of power, performance, reliability, fuel efficiency and now low emissions, it is the technology of choice and the workhorse of the nation's construction sector, powering more than three-fourths of all heavy construction equipment.

Today, roughly 850,000 diesel-powered vehicles nationwide are in use bringing supplies, materials and workers to and from U.S. construction sites. Earthmovers, bulldozers, bucket loaders, backhoes, cranes, pavers, excavators and motor graders are all essential to building and expanding our economic infrastructure. For most of these machines, there is simply no substitute for diesel power. No viable alternative has yet emerged for equipment that exceeds 500 horsepower; some construction engines produce several thousand horsepower.

Building the U.S. Economy

In the construction sector 98 percent of all energy use comes from diesel. Construction accounts for 55 percent of off-road fuel use in the U.S. The U.S. construction industry employs nearly six million people and contributes some $850 billion annually to the economy. This is due in no small part to the power and efficiency of diesel.

Building the Road to Clean Diesel

Construction In 2004, EPA challenged diesel engine and equipment makers to virtually eliminate emissions from a wide range of diesel engines used in construction, farm and industrial off-road applications from massive bulldozers to farm tractors to lawn mowers. Beginning in 2008, manufacturers responded with increasingly low-emissions technology leading up to the 2014 Tier 4 Final standards. The Tier 4 Final emission standards resulted in a 90 percent reduction in PM and 50 percent cut in NOx emissions including from the iconic workhorses of every construction project - wheel loaders, backhoes, excavators and bulldozers.

The incredibly challenging fourth-generation Tier 4 engine emissions standards are also providing greater energy efficiency and productivity. In today’s economy, this combination is vitally important to contractors and may provide a competitive edge. With the increasing demands for green construction practices on infrastructure and public works projects, these new machines will be an essential asset for contractors looking to win these important bids. Construction equipment at work on a road or other public works project deployed with a Tier 4 final engine can also contribute to NOx emissions reduction for a region or locality.

The clean diesel platform is the foundation for hybrid powertrains being incorporated into some excavators, bulldozers and wheel loaders and other off-road machinery. The pairing of the most energy efficient clean diesel engine with hybrid technology can be an irresistible combination for some contractors.
