Project set to boost efficiency of exhaust systems in HDVs

News

The Energy Technologies Institute (ETI) is investing £4.5m in a project to improve the catalytic conversion efficiencies of exhaust systems in heavy-duty vehicles (HDVs).

The ETI-commissioned and funded project will be led by Johnson Matthey, who, in addition to collaborating with Loughborough University, will work alongside ETI member Caterpillar.

According to ETI, diesel-engine fuel efficiency is often reduced by having to comply with exhaust emission standards. It is hoped that the new exhaust system developed by this project will be so efficient that it will effectively remove this constraint, allowing the HDV diesel engine to be more fuel efficient. The project is intended to deliver fuel efficiency and CO2 benefits of between three and four per cent.

Chris Thorne, programme manager of HDV efficiency at the ETI, said: ‘Our modelling work points to efficiency in transport and in the HDV sector as an area that can make a meaningful difference in helping to reduce carbon emissions.

‘However, we have to achieve our CO2 goals while meeting the cost, reliability, space and exhaust emission standards constraints that exist within the HDV market.
