The ever-increasing pressure to reduce greenhouse gas (GHG) emissions from the transport sector poses challenges to the entire industry. Since the release of the new European CO2 fleet emission targets demanding a massive reduction in the upcoming years (-15%/-31% in 2025/2030 vs. the 2021 figures), substantial initiatives have been launched to ensure the development of affordable solutions. goals meeting the market requirements. Diesel powered vehicles and, especially Light-duty Diesel has been the main driver for CO2 emission reductions in recent years. These achievements were mainly based on improvement of combustion efficiency and reduction of mechanical losses. Based on this experience, it appears doubtful to achieve further significant fuel consumption and CO2 reductions with an improvement in engine technology alone. This reduction steps requested by the authorities call for the implementation of new technologies.
The paper in hand describes the conceptual layout of the advanced powertrain topology for heavy LDV applications, balancing functional performance in the operational map with corresponding cost reduction measures. Furthermore, initial functional performance data, especially in comparison to conventional powertrains and serial hybrid layouts, will be presented. The paper concludes with a summary and parameter ranking in order to determine next steps in realization and industrialization of the new concept.
