Modern diesel engines are engineering marvels of power and efficiency — but they also come with a complex web of emissions ...

An off-road machine’s selective catalytic reduction (SCR) system converts toxic nitrogen oxides in a diesel’s exhaust—nitrogen monoxide (NO) and nitrogen dioxide (NO2)—into harmless nitrogen, water, ...

Long-haul truckers and diesel engine enthusiasts had to rethink their entire operations in 2010 when the Environmental Protection Agency mandated selective catalytic reduction technology. Selective ...

For our industry, the year 2027 means meeting lower NOx standards while using less fuel. Under old diesel design rules, this would be quite problematic because NOx forms at the high cylinder ...

Southwest Research Institute (SwRI) has developed a method to automate the calibration of heavy-duty diesel truck emissions control systems using machine learning and algorithm-based optimization. The ...

The efficiency and long-term performance of an SCR System is largely dependent on several key design considerations of the various equipment within the SCR System. When complex NOx reductions on ...

The Environmental Protection Agency and California Air Resources Board have established that NOx and particulate emissions from diesel trucks have an adverse effect on respiratory and cardiac health.

As the quest to develop a net-zero carbon emissions electricity grid marches on, global entities like the International Energy Agency (IEA) increasingly point to a big role for carbon capture, ...

Southwest Research Institute used machine learning tools to automatically calibrate SCR systems while fine-tuning controls to lower overall tailpipe NOx and ammonia emissions. Future work will expand ...

A series of advanced selective catalytic reduction (SCR) systems has been installed on Van Oord’s cable-laying vessel (CLV) Nexus by Damen Shipyards Group in an effort to further reduce emissions.Five ...
