Caterpillar Innovation and Research Centre – Optical diagnostics research with º¬Ðß²ÝÊÓƵ

The I&RC has a proven track record in applying advanced optical-diagnostic techniques to investigate thermo-fluid processes.

This state-of-the-art laboratory is used to provide understanding of fundamental physical interactions and processes within powertrain systems. Working closely with engineers at Caterpillar, research is undertaken to generate new system concepts, improve component design, and support model development.
