Selective catalytic reduction

Caterpillar Innovation and Research Centre – Selective catalytic reduction research with º¬Ðß²ÝÊÓƵ

Featuring advanced optical-diagnostic techniques, the state-of-the-art facilities in the I&RC are fully controllable to replicate heavy-duty vehicle exhaust flows under a wide range of conditions.

Two high-temperature air-flow test rigs are available for experimental research into selective catalytic reduction (SCR) aftertreatment. Research is undertaken to inform simulation activities, provide understanding of the fundamental interactions that occur, and develop new solutions. This pioneering work has led to the development of new system concepts and designs.
