Cummins has more than 60 years of experience developing Holset turbochargers and uses in-house testing facilities to conduct stringent testing and repetitive analysis on new products and technologies.

“Multi-phase Computational Fluid Dynamics (CFD) was used to model the oil behavior in the seal system. This led to a much deeper understanding of the oil/gas interaction and physics at play. This deeper understanding influenced design improvements to deliver the new sealing technology with unmatched performance,” said Matt Franklin, Director – Product Management & Marketing.

Due to this rigorous testing regimen, the final product exceeded the seal capability by five times the projects initial target.
