Introducing The All-New Detroit Diesel DD15

The DD15 takes innovation to a whole new level. This impressive new engine delivers incredible torque response and power, increased fuel economy, extremely long torque range, increased maintenance intervals and a smoother, cleaner ride.

Incredible Torque Response

  • The DD15 delivers 90% peak torque in 1.5 seconds.
    Here’s how:
    – Breakthrough innovation called
    Amplified Common Rail Fuel   System (ACRS™)
    – Simple and reliable pre-EPA ’98   non-wastegated and
    non-variable geometry-style turbocharger
    – Low inertia, dual overhead camshafts

Increased fuel economy

  • A 5% fuel savings* over other leading engines
  • Turbo compounding system recovers normally wasted exhaust gases and turns them into usable power without sacrificing fuel

Extremely Long Torque Range

  • Pulls down to 1000 RPM
  • At just over 1000 RPM, you’re at 90% peak torque
  • Ultra-long flat torque curve for less shifting

Smoother, Quieter engine

  • ACRS reduces emissions, noise and vibration
  • Rear gear train and ribbed cast iron cylinder block with integrated oil and coolant passages minimize vibration and sound
  • Integrated Jacobs® Engine Brake with three levels of braking increases stopping power and reduces noise

Low Maintenance

  • Engine sub-systems are modularly built to simplify parts replacement and maintenance
  • All filters are cartridge style and located above the frame rails for easy replacement
