High Efficiency Selective Catalytic Reduction - Phase 2
This project designed and developed a high efficiency Selective Catalytic Reduction (SCR) System that operated effectively over a wide range of operating conditions and produced low levels of GHG when co-optimised with an engine
About the project
- Developed a more efficient exhaust emission clean up system with new urea injector design
- Aimed to deliver fuel efficiency and CO2 benefits between 3-4%
- Delivered by a consortium from academia and industry
This project was to seek catalytic conversion efficiency improvements of exhaust systems in HDVs.
Launched in November 2012, with an investment of £4.5m, the project was led by Johnson Matthey. The consortium included Loughborough University and Caterpillar.
The 44-month long project aimed to help HDV fuel efficiency by developing a more efficient exhaust emission clean up system (commonly known as a “catalytic converter”). Often diesel engine fuel efficiency was reduced by having to comply with exhaust emission standards. It was hoped that the new exhaust system developed by this project would be so efficient that it would effectively remove this constraint; allowing the HDV diesel engine to be more fuel efficient. The project aimed to deliver fuel efficiency and CO2 benefits of between 3%-4%.
