Lab Spotlight: ORNL - SpaciMS, Meeting Emission Standards

DConT2

Clean diesels and other advanced engines require highly effective exhaust treatment technologies to meet increasingly stringent emissions regulations. SpaciMS (spatially resolved mass capillary input mass spectrometry), an R&D 100 Award-winning diagnostic tool—developed by Oak Ridge National Laboratory (ORNL) and engine manufacturer Cummins—takes samples inside the confined spaces of reactors like automotive catalysts, fuel reformers or fuel cells, measuring changes in chemical composition in both space and time within the reactors. Sampling within the reactor during operation gives a greater understanding of reactor and catalytic chemistry than has previously been possible by measuring reactor exhaust alone. This technology was used in the optimization of the groundbreaking 2007 Dodge Ram heavy-duty pickup truck, which met 2010 emissions control standards three years ahead of schedule.
