Efficiency, Performance & Durability

 The DD8 is the most technologically advanced mid-range engine available in its market. Its features include:

• Proprietary variable cam-phasing technology optimizes efficient aftertreatment system performance by reducing or even eliminating regens. By maintaining the correct temperatures during low-speed operation, it minimizes the need for parked regens, keeping you on the road longer.
• A smart, fuel-efficient design that makes the most of every gallon and lightens the load on the aftertreatment system. 
• Its advanced common rail fuel system optimizes each injection event to minimize fuel consumption.
• A variable-speed fan and advanced cooling system providing shorter fan-on times for increased fuel efficiency.
• Simple, fixed-geometry, turbocharger for performance, efficiency and reliability.
• An optional high-performance integrated engine brake.
• A robust and sturdy rear gear train helps minimize noise, vibration and harshness (NVH).
• PTO Capability – both FEPTO and REPTO – for a variety of vocational work-truck applications.
• Detroit provides a wide range of new vehicle engines compliant with EPA, CARB emissions, GHG, and OBD requirements. Please consult your local dealer to ensure the selection of a product that meets your specific needs.
