Document Type Clarification: This is a supplementary manual, meaning it does not replace the primary service manual for the 3-series but provides in-depth technical detail on the EDC system. ⚙️ Engine Specifications Primary Engine Engine Family: Scania D11 / D14 series (in-line 6-cylinder and V8) Performance Power Outputs: 380 Hp (DSC 11 22), 470 Hp (DSC 14 04), 400 Hp (DTC 11 01), 500 Hp (DSC 14 09) Torque Figures General: Torque figures would be substantial, ranging from approximately 1700 Nm for the 380 Hp variant up to 2000+ Nm for the 500 Hp variant. Exact figures dependent on specific engine variant and RPM. Fuel System Injection Type: Electronically controlled unit pump or common rail system (depending on specific variant and year, EDC implies advanced control). Emission Control Features: EDC facilitates precise fuel injection to meet emissions regulations of its era, contributing to lower NOx and particulate matter compared to purely mechanical systems. Turbocharging and intercooling are standard on these engines. Injection Timing Control: EDC precisely controls injection timing for optimal combustion, emissions, and performance based on engine speed, load, and temperature. Displacement Engine Displacement 11 Liter: Approximately 11.0 liters (for DSC 11 / DTC 11 variants) Engine Displacement 14 Liter: Approximately 14.2 liters (for DSC 14 variants) 🔧 Transmission Standard Typical Transmission Type: Heavy-duty manual transmission (e.g., Scania GRS series) or automated manual transmission (e.g., Scania Opticruise). Optional Automated Transmission Options: Automated manual transmissions (e.g., Scania GR800, GRS900 variants with or without Opticruise control) were increasingly common. Features Transmission Control Integration: Potential integration of EDC with transmission control for optimized gear shifting and performance, especially with automated transmissions. 📐 Dimensions Exterior Chassis Configurations: Wide range of configurations including 4x2,...
