What is Selective Catalytic Reduction? Selective Catalytic Reduction (SCR) is an advanced active emissions control technology system that reduces tailpipe emissions of nitrogen oxides (NOx) down …

Advanced diesel engines minimize the production of emissions through efficient combustion. Controlling remaining emissions involves a series of strategies including particulate filters, oxidation catalysts, …

The significance of the model years (2007 and 2010 and later MY) relates to emissions standards and the introduction of new emissions controls such as particulate filters, oxidation catalysts, and …

“Since 2010 for highway vehicles and 2014 for most non-road equipment, achieving near-zero emissions of particulate matter and nitrogen oxides in these engines is accomplished by an advanced …

Diesel is the most energy-efficient internal combustion engine. Learn more about diesel and its relationship to climate change.

Thanks to the advanced filters and selective catalytic reduction systems, harmful emissions and health-effects related concerns from previous generations of vehicles without these technologies were …

The data examines the number of 2010+ model year diesel trucks operating today. They’re equipped with advanced diesel engines that minimize the production of emissions through efficient …

In 2010 selective catalytic reduction (SCR) systems were added and became near standard fare to reduce nitrogen oxide emissions. Emissions regulations for off-road engines and equipment …

The Tier 4 generation of technology for off road engines and equipment followed a similar path to that from the emission reduction requirements for engines that power heavy-duty trucks. While engine …

Achieving near zero emissions is enabled by new particulate filters and selective catalytic reduction technology that reduces nitrogen oxides to other compounds. Advanced diesel technology buses are …
