What is thermal management in an aftertreatment system? Advanced aftertreatment technologies reduce emissions and meet strict environmental standards. These technologies use catalysts to capture and reduce emissions from exhaust gases, but they need precise thermal management to work well. By maintaining an optimal temperature range, we ensure maximum performance, helping to improve air quality
When learning about components that help vehicles run more efficiently and safely, knowing about Exhaust Throttle Valves is crucial. An Exhaust Throttle Valve is a part of the engine that controls how exhaust gases flow out of the engine. It helps reduce pollution by making the engine work hard so it will warm up the aftertreatment system faster. It can also be used as an engine brake by creating
Power electronics convert and control electric power in vehicles, ensuring optimal performance and efficiency. By managing power use, they enable longer distances, reduce energy waste and support sustainable transportation. In Part 1, we explored the role of power electronics in battery electric vehicles (BEVs). This article focuses on their role in fuel cell electric vehicles (FCEVs), highligh
As alternative fuels and vehicle technologies gain traction, the role of components within these technologies is evolving. In battery electric vehicles (BEVs), power electronic components are critical to vehicle functionality and efficiency. Understanding their impact and potential is essential for businesses adopting BEVs or navigating the future of sustainable transportation. Previously, we d
On Nov. 1, Cummins Inc. (NYSE: CMI) launched Project Unity, a collaborative effort with Holtex and the University of Manchester to develop an advanced digital tool aimed at improving the design and durability of components used in hydrogen-fuelled powertrains. Project Unity employs machine learning-driven digital tools to accelerate speed to market by predicting long-term failure modes in criti
Cummins Drivetrain and Braking Systems (CDBS), a part of Cummins Inc.’s Components segment, is ramping up production capacity for air disc brakes (ADBs) and rear axles with strategic investments totaling over $190 million. These investments underscore Cummins’ commitment to meeting the increasing demand for advanced braking and axle solutions in the commercial vehicle sector. The industry is witne
A decade ago, turbochargers for natural gas and diesel engines were not very different. However, new emissions regulations have driven the development of turbochargers specifically designed for natural gas engines. These turbochargers are adapted to stoichiometric burn conditions, where the mix of oxygen and fuel is precisely balanced. This balance ensures efficient combustion, leaving no unburnt
At Cummins Inc., we’re constantly looking for ways to advance sustainable transportation solutions. As the industry shifts to lower-emission fuels to reduce pollution, natural gas engines are one critical pathway to cleaner mobility. Cummins is therefore working to innovate component-level technologies supporting natural gas engines. Understanding how natural gas engines work and the components
Emission regulations have become crucial in reducing the environmental impact of heavy-duty vehicles. The implementation of U.S. Environment Protection Agency’s (EPA) 2027 emission standards in North America is expected to be a significant milestone in this ongoing endeavor, drastically lowering nitrogen oxide (NOx) emission limits by over 80%. The standards also dictate the extension of the emiss
As fleets work towards reducing emissions, understanding the differences in aftertreatment systems for various fuel types is crucial. The adoption and growth of hydrogen internal combustion engines (ICE) is a significant step as hydrogen ICE provides a low-emission, low-carbon option for a more sustainable transportation sector. The mechanisms that clean exhaust gases in these engines are fundamen
The transportation industry is navigating the delicate balance between performance enhancement and sustainability. A pivotal aspect of this journey is the evolution of engine braking and Valvetrain technologies due to the direct link these components have with engine performance and fuel consumption. This article helps explain the latest developments around braking and Valvetrain technologies, and
Engine and vehicle OEMs are faced with the difficult task of streamlining their engine platform and adjusting it for global markets – each with its own emissions regulations and power requirements. To allow for more flexibility, our engineers have been working on “future-proofing” engines with in-engine modular valvetrain technologies to allow engine platforms to be adjusted to varying globa
