‘Cleaner’ Trucks a Direct Result of Advanced Semi-Truck Parts Design


Shaun Stille

More trucks in the U.S. are becoming ‘cleaner,’ as opposed to the ones that roamed America’s major roads and highways decades ago, mainly due to the continued advancement of semi-truck parts design. As AutoBlog Green’s Danny King notes in his article: “When it comes to diesel trucks, the good old days weren’t so good. Go back a quarter century, for instance. Back then, a singe diesel-powered truck was throwing off about 60 times the emissions a typical ‘clean diesel’ truck goes today.”

todays semi trucks are a lot cleaner than they used to be

According to information from the Diesel Technology Forum, up to 33 percent of all trucks currently traversing U.S. highways are ‘cleaner’ versions of their smoky, older counterparts. About 2.9 million of 8.8 million trucks in all of America are now sporting newer, cleaner diesel engines. This data includes information on mostly class 3-8 trucks between 2007 and 2013, which were registered in the District of Columbia and all 50 states.

Diesel Technology Forum Executive Director Allen Schaeffer notes the great improvement in the fight to reduce harmful diesel emissions, noting that while 75 percent of all heavy-duty trucks are diesel-powered, more than a third of such trucks are near zero-emission vehicles. He also goes on to say that the newer trucks are so clean, that it takes about 60 of them to equal the emissions of a single 1988 edition freight truck.

In this extensive push to decrease harmful diesel truck emissions, the past decade has been absolutely great. Heavy-duty truck, bus, and smaller vehicle emissions have been virtually reduced by 99 percent for nitrogen oxides (NOx)—an ozone-depleting substance—and about 98 percent for particulate emissions.

The effort is primarily one result of the combined capabilities of the Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA), both of which established a national program to reduce diesel fuel emissions and establish new fuel efficiency standards for commercial vehicles. Set to begin this year until 2018, the regulation is anticipated to significantly slash about 500 million barrels from the currently 22-billion gallon fuel consumption of American freight truck fleets.

For business owners who have a fleet of freight trucks that they use almost daily, it is probably best to join in on the revolution. A great selection of new semi-trailer parts sold by leading dealers like Global Parts Inc. is available and designed to maximize any truck’s fuel efficiency and significantly decrease its harmful gas emissions.
