Keywords: hybrid power train, simulation, internal combustion engine technology
Reducing the fuel consumption and thus the CO2-Discharge of vehicles is one of the prior targets in engineering new vehicles. An approach to handle this topic is a hybrid power train, which not only reduces the fuel consumption but also offers potential to raise the performance and lower emissions of the vehicle. Depending on the requirements the architecture and the dimension of the components of hybrid power train have to be chosen. The combination of Systems which complete each other in their specific attributes is to favour. Tools for power train simulations facilitate the chose of components and ease finding the optimal dimensions. Furthermore specific adaptations of components can be focused on the simulation results and thus shorten the work on the test bench. A comparison of three different types of internal combustion engines for the usage in a parallel hybrid power train was carried out with the help of power train simulations. The potentials are shown and concerted adaptations are defined. These adaptation are carried out on the engine test bench. With the achieved data further simulations are carried out to describe the influences on hybrid operation state.
