Energy Integration On Multi-Periods For Vehicle Thermal Powertrains

Internal combustion engines are the most applied energy converters in passenger cars. In order to increase their efficiency, energy integration techniques are used to recover waste heat. An adapted methodology is required to design the organic Rankine cycle (ORC) as a waste heat recovery technology and to test the influence of the external temperature on its efficiency. The idea is to cluster the external temperature profile on typical external temperature multi-periods. The energy system design is then tested on these typical multi-periods. In this article the methodology is applied on a vehicle with a diesel engine, in order to define the energy integrated configuration of the vehicle and to estimate the cost of the additional equipment. The performance indicators of the energy integration technology of the internal combustion engine is done and discussed, according to the multi-periods. The energy recovery potential of a single stage ORC for a diesel engine is assessed for different temperature profiles. The ORC equipment is simultaneously pre-sized and its cost is estimated.
