The new sealing technology for Holset® turbochargers allows turbo down speeding, downsizing, oil leakage prevention on two-stage systems and enables CO2 and NOx reductions for other technologies. The technology has also improved thermal management and reliability of the turbocharger. In addition, due to its robustness, it has positively affected the frequency of maintenance of a diesel engine.

Other key elements were also taken into consideration when the sealing technology was in the research and development stages. These include allowing for optimisation of the compressor stage diffuser and a drive for closer integration between the aftertreatment and turbocharger, an integration which has already been subject to significant R&D from Cummins and forms a significant part of the Integrated System concept.
