Emission regulations in North America and Europe are pushing the heavy-duty vehicle industry to adopt innovative aftertreatment solutions to meet stringent standards. The article discusses how the implementation of EPA's 2027 emission standards in North America is a significant milestone, lowering nitrogen oxide (NOx) emissions by over 80% and requiring the extension of emissions useful life (EUL) of vehicle components. Cummins Inc. is introducing the Twin Module, a new aftertreatment architecture powered by a 48V alternator and featuring an electric heating system to meet the EPA27 regulations while maintaining engine performance and durability. By utilizing electric heating technology, the Twin Module offers precise thermal management and scalability for future emission standards. In Europe, the Euro 7 emission regulations starting in 2027 also pose challenges for OEMs to reduce NOx and meet CO2 reduction targets. Cummins Emission Solutions provides a range of components to support OEMs in achieving compliance. The article emphasizes the importance of industry collaboration and technology innovation to ensure that heavy-duty vehicles meet evolving emission standards while delivering optimal performance and fuel efficiency.
