Horsepower typically ranges from 300 to over 550 HP, and torque from 1050 to over 1850 lb-ft. DDEC (Detroit Diesel Electronic Control) systems manage fuel injection, timing, and engine performance parameters. Fuel System Fuel System: Electronic Unit Pump (EUP) system managed by DDEC ECM. Includes high-pressure fuel lines, injectors, fuel filter(s), fuel pump, and fuel rail pressure sensors. 🔧 Transmission Standard Standard: Various heavy-duty manual and automated manual transmissions (e.g., Eaton Fuller, Allison) are commonly paired with the Series 60 engine. Specific pairing depends on the Kenworth model and application. Optional Optional: Automatic transmissions (e.g., Allison) are also available for specific applications. Features Features: The DDEC Series 60 ECM often interfaces with transmission control modules (TCMs) for integrated powertrain management, including electronic shifting and torque management for optimal performance and durability. 📐 Dimensions Exterior Exterior: Varies significantly based on the specific Kenworth truck model (e.g., T600, T660, T800, W900). Overall length, width, and height are determined by cab configuration, chassis type, and axle configuration. Interior Interior: Cabin dimensions and layout vary based on Kenworth model and trim (e.g., day cab, extended cab, sleeper cab). Cargo Cargo: N/A (This manual covers the engine's electrical system, not cargo specifications). Weights Weights: GVWR (Gross Vehicle Weight Rating) and GCWR (Gross Combination Weight Rating) are highly variable, determined by chassis, axle configuration, and intended application. 🛡️ Safety Features Ratings Ratings: N/A (This manual focuses on electrical systems, not vehicle safety ratings like NHTSA or IIHS. However, proper functioning of engine electronics is crucial for vehicle safety systems like ABS and stability control that interface with the powertrain). Active Features Active Features: ABS, Traction Control, Electronic Stability Control (ESC) often integrate with engine management. The DDEC system's ability to control engine torque is vital for these systems. This manual provides wiring for these interconnections.
