Hybridization of the powertrain is one effective measure to meet future legislation requirements regarding the reduction of CO2 emissions from heavy-duty vehicles. Additional impacts of this hybridization on the internal combustion engine's exhaust behavior and derivation of boundary conditions for the operation of exhaust aftertreatment systems is subject of research on an engine-in-the-loop test bed at Technische Universität Darmstadt.

1 Motivation

The recent proposal for future CO2 emissions for heavy-duty vehicles presented by the European Commission (EC) at the end of 2018 requires a tank-to-wheel CO2 emission reduction of 15 % in 2015 and 30 % in 2030 based on current values [1]. In order to achieve this significant improvement in fuel consumption associated with CO2 emissions, new measures have to be introduced in the heavy-duty powertrain architecture. In the passenger car sector, hybridization of the powertrain has proven to be an effective measure for reducing CO2emissions...
