Third Report to Congress: Highlights from the Diesel Emission Reduction Program

From goods movement to building construction to public transportation, diesel engines are the modern-day workhorse of the American economy. Though diesel engines are reliable and efficient, older ones emit significant amounts of exhaust including particulate matter (PM) and nitrogen oxides (NOX), which can harm human health. Despite the recent implementation of the U.S. Environmental Protection Agency’s (EPA) most stringent emissions standards, approximately 10.3 million older diesel engines remain in use. EPA began awarding clean diesel grants in 2008 under the Diesel Emissions Reduction Act (DERA), a grant program created by Congress as part of the Energy Policy Act of 2005 to reduce diesel exhaust from these older engines. EPA’s National Clean Diesel Campaign (NCDC) within the Office of Transportation and Air Quality administers the DERA grants. EPA awarded the first DERA grants in 2008, the American Recovery and Reinvestment Act (Recovery Act) grants in 2009, and grants from funds appropriated in Fiscal Years (FY) 2009 through 2015. This Third Report to Congress covers final results from the Recovery Act and FYs 2009-2011 and estimated results and benefits from funding in FY 2011- 2013. Read More

Diesel Exhaust

Diesel exhaust is a mixture of over 400 different fine particles, vapors, and toxic organic materials, that result when diesel fuel is burned. Over 40 chemicals in diesel exhaust are considered toxic air contaminants (TAC) by the State of California.

Diesel Exhaust Aftertreatment 2000-2007

Library Holdings. Diesel engines continue to be widely used in heavy-duty commercial applications around the world, and they are also gaining popularity in light-duty applications such as passenger cars. With this comes increased concern for and regulation of diesel emissions – most notably particulate matter (PM) and nitric oxide (NOx) emissions. Read More

Program Update: Reducing Air Pollution From Non-road Vehicles

The EPA has adopted emission standards for most categories of new non-road engines. This paper summarizes the status of those programs. Included are: land-based diesel engines, land-based spark-ignition engines, marine engines and vessels, locomotives, and aircraft. Read More

Heavy Trucks, Buses, and Engines

This site offers numerous sites with information concerning heavy duty engines used for urban, commercial, off road and civil applications. Under the new EPA proposed guidelines for monitoring diesel emissions, diesel engine manufacturers will be required to measure their emissions using actual highway applications and driving conditions as opposed to testing conducted in a lab environment.
