SUMMARY

This project looked at adapting waste heat recovery technologies for diesel rail vehicles (diesel multiple units, DMU). Entropea Labs Limited and Brunel University have proposed a technology that consists of a mild-hybridisation of the DMU vehicle powertrain to reduce fuel consumption and pollutant emission. A modular non-invasive Waste Heat Recovery System based on the Organic Rankine Cycle was developed for retrofitting to the DMU powertrain or placing on new vehicles. The proposed technology focuses towards a mild-hybrid configuration, allowing for a cost-effective solution that improves the efficiency of a DMU vehicle.
