Waste heat recovery for diesel vehicles

Waste heat recovery for diesel vehicles

Entropea Labs Limited and Brunel University 


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.
