Working at the forefront of NOx (oxides of nitrogen) reduction technology since 2010, Loughborough experts have developed a novel system that extends the low-temperature operation of AdBlueTM based Selective Catalytic Reduction (SCR) systems.

SCR systems help reduce NOx emissions from both on-highway and heavy-duty diesel engines. However, these systems struggle to operate at exhaust temperatures below 250ºC which can result in exhaust blockages if the system is not shut down.

The new Loughborough technology – ACCT – integrates into existing SCR systems, requiring very little design alteration. Crucially, by extending the system’s operating temperature range, ACCT dramatically lowers NOx emissions and allows for further fuel efficiency improvements.

As legislation reducing engine emissions imposes ever lower targets alongside stringent penalties for non-compliance, pressure on vehicle manufacturers to improve SCR efficiency is mounting – creating global demand for ACCT.

Commercialisation activity is already underway to bring this unique technology to market.
