The automotive industry is undergoing a deep transformation that will shape its future for the next decades. In order to achieve the CO2 fleet average requirements, the share of electrified powertrain is rising. It is now possible to design powertrains using not only the highly efficient internal combustion engines (ICE) but also the newly developed electrical motors (eMotor) and batteries. This variety of technologies allows the design of sophisticated powertrain to better fulfill the requests not only regarding CO2 regulations but also of different markets, customer expectations and emission legislations. The increased variety of powertrains causes, on the other hand, some challenges regarding the exhaust after treatment systems (EATS) layout and emission control, considering the almost infinite possibilities to combine ICE and eMotor’s toque delivery to fulfill the customer desired drive profile.
