In order to reduce traffic-related emissions of both greenhouse gases and pollutants, new powertrain concepts are necessary. Phlegmatised internal combustion engines as part of hybrid powertrains offer a significant potential for efficient, clean and affordable mobility. In this paper, a modular and scalable serial hybrid powertrain concept is presented. Phlegmatisation enables the use of regenerative fuels in innovative combustion processes, such as Prechamber Combustion (PCP) or Reactivity Controlled Compression Ignition (RCCI). Functional requirements regarding vehicle performance are derived from 1D simulation, based on real driving data. Powertrain components are then dimensioned to meet the set requirements. An outlook is given towards an intelligent operating strategy, predicting power requirements on the route ahead. A Dynamic Programming approach to this predictive strategy is shown to offer considerable potential to improve efficiency, driver comfort and battery life. The basic design of the powertrain components and the operating strategy is validated simulatively.
