PROJECT LAUNCH TO IMPROVE EFFECTIVENESS OF SCR SYSTEMS FOR HEAVY-DUTY VEHICLES
Published on 16.01.2013
The UK public-private partnership Energy Technologies Institute (ETI), Loughborough University, Johnson Matthey and Caterpillar have launched a new £4.5-million (€5.4 million) technology project to improve the effectiveness of Selective Catalytic Reaction (SCR) aftertreatment systems for NOx reduction in heavy duty vehicles (HDVs). The project aims to help HDV fuel efficiency by developing a more efficient exhaust aftertreatment system. Often diesel engine fuel efficiency is reduced by having to comply with exhaust emission standards. It is hoped that the new exhaust system developed by this project will effectively remove this constraint. The project aims to deliver fuel efficiency and CO2 benefits of between 3%-4%.
The ETI commissioned and funded project will be led by Johnson Matthey, which in addition to collaborating with the university, will also work alongside ETI member Caterpillar. The work by the university will be carried out by the School of Mechanical and Manufacturing Engineering.
This project is part of a £40-million (US$64 million) ETI program focused on increasing HDV efficiencies. Officially launched last year, the program aims to improve systems integration and technology development across the HDV sector (including trucks, buses, agricultural machines, construction equipment, quarry and mining machines, and marine transportation)—with an aim to increase the efficiency of land and marine vehicles by up to 30%.
