DD PLATFORM APPLICATION AND INSTALLATION MANUAL 1 INTRODUCTION The DD Platform engines are a new line of six cylinder four–stroke diesel engines. The DD15™engine has a displacement of 14.8L, horsepower ranging from 455 to 560 BHP, and torque ranging from 1550 to 1850 lb·ft. The engine is also equipped with a turbocompound system for improved fuel economy. The DD13™shares very similar architecture and layout to the DD15™engine, but with a displacement of 12.8L and no turbocompound system. Horsepower ratings are available from 350hp to 450hp and torque from 1350ft-lb to 1650 lb·ft.
Vital features of the DD Platform engines include an amplified common rail fuel injection system, dual overhead camshafts, an integrated Jake Brake®, DDEC VI electronic control system, active aftertreatment, outstanding NVH characteristics, and torque response that delivers 95% of peak torque at an engine speed of only 1000rpm. The electronic control system is the Detroit Diesel Electronic Control System (DDEC®) — an advanced electronic fuel injection and control system. The engine calibration programmed in the memory of the Motor Control Module (MCM) uniquely defines the operational characteristics of the engine.
The Common Powertrain Controller (CPC) contains all of the vehicle functionality. Unique DD Platform engine features include: Variable Speed Governor Fuel economy incentive Emissions, smoke, and noise control Torque limiting Progressive Shift Throttle inhibit Engine protection Engine diagnostics Optimal idle Engine brake controls Cruise control This manual covers engine models: All information subject to change without notice. 1-1 DDC-SVC-MAN-0073 Copyright © 2009 DETROIT DIESEL CORPORATION
