Two-Stage Systems

With more than 25 years’ experience in development, testing and application, Cummins Turbo Technologies produces world-class two-stage systems proven to exceed requirements from a vast array of applications. The systems utilize various proprietary component technologies and designs to meet leading emissions requirements.

M2 Modulated Two-Stage System

The Holset M2™ system provides modulation capability using any of the following variable turbine technologies; Holset Wastegate, Holset VGT™ or Holset Rotary Turbine Control (RTC) technology. The modulated two-stage system can have a high-pressure turbocharger far smaller than that of a conventional Two-Stage system, improving transient performance by reducing the turbocharger lag that affects both driveability and emissions.

Product Features & Benefits:

  • Enables higher engine horsepower density for engine downsizing and increased power levels
  • Efficient ultra-high boosting capability with fewer turbo limitations
  • Extended air flow range flexibility
  • Superior altitude air capabilities without exceeding limits
  • Reduced air handling controls complexity
