Reduction of exhaust emissions of diesel-powered railway systems using an innovative, power-split hybrid drive train
In cooperation between the Institute for Machine Elements and Systems Engineering (iMSE) and the ISEA, an innovative, power-split hybrid drive for diesel railcars is developed, which avoids emissions in stations or tunnel sections and improves the efficiency of diesel-powered commuter trains. The HybridRail drive consists of a power-split transmission, a diesel engine, two electric motors and an energy storage unit.
The control of the transmission enables various driving modes, for example starting up without active running combustion engine. Furthermore, the combustion engine can be operated largely at its optimum operating point and braking energy can be recuperated into the energy storage unit in order to charge it while driving.
