Summary

In recent years electro-mobility or e-mobility acquired a firm hold in the field of powertrain technology. Up to now the focus has been on passenger cars however this technology is also applied in commercial vehicles, CVs, and it is becoming apparent that it continues to spread. While the application of e-mobility in passenger cars is mainly driven by the upcoming CO₂legislation, the most important factor for CVs is cost effectiveness, of which the most substantial part is fuel economy. There is still potential for increasing the efficiency of the engine itself, but this will only be possible in small steps, however especially in urban areas with a high number of vehicle stops and starts, the utilization of recuperated braking energy promises to yield very high fuel savings. The following article shows the impact on and potential of a hybrid diesel engine, in particular taking into account EuroVI emissions legislation.
