How does Cummins VGT™ Turbocharger improve performance?
• Cummins VGT™ Turbocharger has a patented one-piece sliding nozzle design that provides exact boost across the operating range. The sliding nozzle varies the exhaust gas flow into the turbine wheel to provide rapid boost at low engine rpm and then maintain high boost at higher rpm. The VGT™ design combines the benefit of both a small and large turbocharger in a single unit, enabling Cummins Tier 4 Interim to achieve significantly improved response compared to a Tier 3 engine demonstrated in customer field tests. Manufactured by Cummins Turbo Technologies, the VGT™ Turbocharger is a key technology asset in not only meeting emissions but increasing engine performance and improving fuel efficiency. Introduced with Cummins on-highway EGR engines in 2002, total VGT™ production is approaching three million units, demonstrating outstanding in-service reliability.
