This study analyses by means of experiments and total vehicle numerical simulation how the available exhaust heat should used within a vehicle in order to obtain the best possible CO2-reduction and/or, if necessary, heating performance. Within this context different concepts for heat usage and distribution are discussed. Moreover a sensitivity analysis is presented, analysing which constructional and ambient parameters are dominant influences on the system performance with regard to the benefit of accelerated powertrain warm-up. Thus the presented results offer a possible reference when the introduction of such systems into a given vehicle fleet is under consideration.
