Power management company Eaton announced its eMobility business introduced a 48-volt programmable power electronics control unit for electrically heated catalysts that can be used by commercial vehicle manufacturers to meet tightening global emissions regulations.

Rapidly warming up the exhaust aftertreatment catalyst, and keeping it warm during low engine load operation, is essential for optimal performance to reduce nitrogen oxide (NOx) exhaust emissions, according to Dublin-based Eaton, whose North American operation is in Galesburg, Mich.

The air-cooled electric catalyst heater controller is part of Eaton’s broader 48-volt electrical system portfolio, which contains several technologies that allow manufacturers to integrate 48-volt architectures in next-generation vehicles.



Eaton noted this technology comes at a time when vehicle manufacturers are facing tightening emission standards around the globe. In Europe, the next stage of emission standards, known as Euro VII for heavy-duty diesel trucks, is targeted for introduction as early as 2026. In the U.S., the California Air Resources Board and U.S. Environmental Protection Agency are introducing more stringent regulations for commercial vehicles in 2024 and 2027.

Eaton reported revenue of $19.6 billion in 2021 and serves customers in more than 170 countries. — Transport Topics
