What are the upcoming emission regulations in North America? The EPA27 emissions rule is a set of regulations established by the Environmental Protection Agency (EPA) to significantly lower nitrogen oxide (NOx) emissions from light-, medium- and heavy-duty vehicles. These regulations take effect with the 2027 engine models and require a reduction in NOx emissions by more than 75% compared to cu

Cummins Turbo Technologies (CTT) has been developing and testing turbocharger technologies with a special focus on medium-heavy duty engines. For the past, several decades Cummins Components and Software has delivered durable and reliable turbocharger solutions with the Holset® brand.  Commercial engines need advanced technology to be efficient and meet strict emissions standards. Therefor

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
