As diesel engine NOx emissions regulations become more stringent, keeping the aftertreatment system at its optimal operating temperature becomes more important. Eaton is developing multiple technologies for commercial vehicles.​

​Eaton’s fuel burner air source is designed to deliver precise and efficient combustion plus cooling air to Tenneco’s Cold Start Thermal Unit (CSTU) fuel burner. ​

​The Eaton 48-volt e-heater controller regulates and supplies power to a heating coil in the vehicle’s aftertreatment system, while ensuring high power quality for the electrical components.
