Technology Solutions for Cleaning-Up Heavy-Duty Vehicles Michael Geller MECA Abstract: This presentation includes results from two recent MECA-authored white papers that assess market-ready technologies being commercialized by suppliers of emission control and efficiency components for heavy-duty diesel vehicles to meet lower intermediate standards for NOx by 2024 as well as final standards in 2027. The ...

Review of Vehicle Engine Efficiency and Emissions Dr. Ameya Joshi Corning Incorporated Abstract: To say that 2020 was a special year would be an understatement. While we would like to forget most of it, there were major changes to the mobility sector and the drive towards sustainable transportation which are worth reviewing – and will ...

Structural Interconversion of Agglomerated Pd Domains and Mononuclear Pd Sites in CHA Zeolites for Passive NOx Adsorption Dr. Raj Gounder Purdue University Abstract: Pd-exchanged chabazite (CHA) zeolites have received interest as passive NOx adsorbers (PNA) that mitigate vehicular NOx emissions during cold-start conditions. Mononuclear Pd cations are proposed precursors to low-temperature NO adsorption sites. In ...

Challenges in emission control of natural gas and hydrogen engines Prof. Olaf Deutschmann Karlsruhe Institute of Technology Abstract: Lean-operated internal combustion engines fueled by natural gas (NG) or hydrogen have attracted a lot of interest recently due to their potential to reduce or avoid emissions of greenhouse gases. Since the fuel is burnt by air ...

Laser-based Ammonia Imaging and Prospects for other Applications of Absorption Spectroscopy in Aftertreatment Systems Prof. Scott Sanders University of Wisconsin Abstract: First, this talk will describe ammonia imaging experiments performed at Cummins Emission Solutions.  In that work, we used a 10.4 um laser to image ammonia concentration in a diesel aftertreatment system.  Optical access through ...
