CLEAN DIESEL TECH IS LIKE TAKING 6,000,000 CARS OFF THE ROAD EACH YEAR
The introduction of more advanced diesel truck engines, innovative emissions control systems, and cleaner diesel fuel over the past decade have successfully resulted in major improvements in air quality and fuel efficiency, according to new research compiled by The Martec Group, a global technical marketing research firm, for the Diesel Technology Forum.
“It is clear from these findings that the new generation of clean diesel technology is delivering large and expanding benefits to society in the form of fewer emissions and lower fuel consumption," said Allen Schaeffer, Executive Director of the Diesel Technology Forum.
The 4,000,000 cleaner heavy-duty diesels introduced from 2007 through 2015 have saved U.S. consumers:
29 Million tonnes of CO2
7.5 Million tonnes of NOx
218,000 tonnes of Particulate Matter (PM)
2.9 Billion gallons of diesel
69 Million barrels of crude oil
Schaeffer notes the reductions from the 2007 and newer trucks on the road today are equivalent to:
Removing the CO2 emissions from 6.1 million light-duty cars from the road for 1 year
Removing the NOx emissions from all light-duty cars for 2 years
Removing the particulate matter from all light-duty cars for 6 years
Schaeffer said 42 percent of all medium and heavy-duty diesel commercial trucks (Classes 3-8) in operation in the United States – four million of 9.5 million diesel trucks – were now equipped with newer technology clean diesel engines; up from 38 percent last year.
Class 8 trucks running the newest generation (2010 and newer) engines saved truckers$2,400 a year in fuel costs by using 875 fewer gallons of fuel (based on 125,000 miles traveled).
"These new clean diesel trucks are a key element in the clean air plans for states to meet the current and future national ambient air quality standards," noted Schaeffer.
The Martec Group also calculated the emissions benefits achieved in selected states. Look at the results from 2011-2015 in these key states where new technology diesel engines is in use:
California has removed 700,000 tonnes of NOx from the atmosphere and saved 2.5 million tonnes of CO2.
New York has removed 250,000 tonnes of NOx from the atmosphere and saved 900,000 tonnes of CO2.
New Jersey has removed 160,000 tonnes of NOx from the atmosphere and saved 500,000 tonnes of CO2.
Pennsylvania has removed 300,000 tonnes of NOx from the atmosphere and saved 1.3 million tonnes of CO2.
“As the world’s attention is now focused on meeting future international climate commitments, it is important to recognize the fuels and technologies that are delivering proven benefits here and now in communities all across America, because technologies like clean diesel will also be vital to achieving those future goals as well,” Schaeffer said.
New Regulations Lead to Environmental & Efficiency Improvements
In December 2000, the U.S. Environmental Protection Agency established new requirements to reduce emissions from on-road heavy-duty trucks and buses by up to 95 percent and cut the allowable levels of sulfur in diesel fuel by 97 percent by 2010. The first requirement for a 98 percent reduction in particulate matter became effective in 2007. In 2010, requirements for a 98 percent reduction in NOx from 2007 levels went into effect.
To achieve these new standards, the new clean diesel system relies on an efficient engine and combustion system utilizing the most advanced fuel-injection, turbocharging and engine management strategies coupled with advanced emissions controls and after-treatment technologies including particulate filters and selective catalytic reduction (SCR) systems - all running on ultra-low sulfur diesel fuel.
