Lowest greenhouse gas emissions along with new regulation worldwide such as US Omnibus, European VII/7 and Bharat Stage CEV/Trem V point the way forward for all future combustion engines applications to emit lowest NOX levels at all working conditions.
Historically, in addition to specific heat modes and change of combustion process to address robust emission control, lowest CO2 target has been “decoupled” from exhaust aftertreatment emission control.
Meanwhile, advanced powertrain architectures such as hybrid technology and applications with electrical storage/energy recovery capabilities are opening up new system innovations for lowering CO2 emissions combined with close coupled system architectures.
Thermal management technologies such as the proven Electrically Heated Catalyst (EHC) and the newly developed Electrically Heated Disc (EHD), which enable Exhaust Gas Aftertreatment System (EATS) to be heated with highly dynamic profiles, allow emissions regulation compliance with minimum CO2 penalty over a wide working range.
This paper shows real-life examples of EHC-EHD systems with modular building blocks both for on-road and off-road applications, demonstrating the high level of integration with reduced impact on existing EATS architectures for global applications.
