DD15

Our engineers continue to refine and improve many features of the DD15 to reach a new level of performance and efficiency.

Product Highlights

A three-stage integrated Jacobs® engine brake for quieter engine braking and superior braking power
A robust rear gear train
A cooling system with shorter fan-on times for increased fuel efficiency
An Amplified Common Rail System (ACRS™) to optimize combustion control
2017 Greenhouse Gas (GHG17) and 2016 OBD (OBD16) compliance
A proprietary asymmetric turbocharger, optimally matched to the updated Exhaust Gas Recirculation (EGR) system, delivering outstanding performance
Optimized piston design for reduced friction and improved engine performance and durability
A variable-speed water pump that utilizes a viscous clutch between the pulley and impeller drive to reduce impeller speeds, making it more efficient than a gear-driven design
