  • The reduction of CO2 emissions and fuel consumption is still the main requirement for the development of new vehicle drive trains. Several technically interesting solutions are intensively developed or will have their start of production soon. Some of them are already well known, but due to cost reasons they are not in production until now. One example is thermal management technique, which uses energy losses to heat up the engine faster to reduce the friction torque and therefore the fuel consumption. Another approach is the electrification, which covers the use of electrically driven auxiliaries, hybrid and electric vehicles. Simulation got a completely new significance for the successful and fast development. On the one hand it is useful and even necessary to assess and select the various numbers of possible solutions with complex interactions virtually. On the other hand the influence of particular solutions to the fuel consumption is within the measurement accuracy, which means that simulation is the only way of assessment.
    This paper describes the simulation of the thermal behavior of hybrid vehicles as well as the energy recuperation from exhaust gas by means of thermo electrical generator for selected applications under the aspect of CO2 reduction. For the virtual consideration the commercial 1D thermal management software KULI with integrated driving simulation module for the evaluation of driving cycles was used.
