Cummins has unveiled its research and development investment in oil sealing technology for Holset turbochargers. Its latest research reduces the risk of machine failure through the development of "a more robust sealing system," according to the company. Elements that were considered while the technology was in the development stages included:
Turbocharger Efficiency: The non-contact seal system design enables good transient response by not introducing additional friction to the rotor system. The technology also allows optimization of the compressor stage diffuser and wheel line up for efficiency gains.
High bypass: The concept Integrated System, featuring bypass technology, is one of the research methods Cummins is investing in to achieve better system integration for turbocharger efficiencies and thermal management improvements.
According to the company, the technology is currently undergoing a patent and can be used on both on-highway and off highway applications. It will be available to customers this month.
