Power the Evolution

Our engineers re-examined, then re-designed many features of the DD15 to reach this level of performance, including:

  • Proprietary Asymmetric Turbocharger to reduce weight and complexity, and deliver improved performance over other turbo designs. It is also more optimally matched to the Exhaust Gas Recirculation (EGR) system to deliver outstanding performance.

  • Next generation ACRS Fuel System optimizes DPF regenerations through improved combustion control to extend regeneration intervals.

  • Fuel Filter Module uses a two-filter system for longer service life, increasing the service change interval up to 100,000 miles. Serviceability has improved, with easier access to the water drain and fewer priming strokes.

  • Optimized Piston Design introduces a carbon scraper ring, reduces oil consumption, and contributes to improved fuel economy.

  • Variable Speed Water Pump utilizes a viscous clutch between the pulley and impeller drive to reduce impeller speeds, making it more efficient than a gear-driven design.

  • Optimized Oil Pump contributes to greater fuel economy.

  • Weight Savings of 100-pounds compared to EPA 10.

  • Meets 2013 OBD (OBD13) and 2014 Greenhouse Gas (GHG14) regulations.
