Horsepower ranges typically from 300 to over 500 HP. Torque Output: Highly variable based on specific engine model and OEM configuration. Torque figures typically range from 1200 to over 1850 lb-ft. Fuel System Injection System: High-pressure common rail with electronically controlled injectors Fuel Type: Diesel fuel Emissions Compliance Emission Standards: Varies by model year and region; typically meets EPA and CARB emissions standards of its production era (e.g., EPA 2007, EPA 2010 depending on the specific V-Mac IV implementation). 🔧 Transmission Standard Transmission Integration: V-Mac IV system integrates with various heavy-duty transmissions (e.g., Mack mDRIVE automated manual, Eaton Fuller manual and automated manual transmissions). Optional Transmission Control: ECM can provide shift control signals and receive transmission status information for optimized performance and fuel economy. Features Gear Selection: ECM influences shift points and torque delivery for smooth and efficient gear changes. 📐 Dimensions Exterior Vehicle Platform: Applicable to various Mack truck chassis models (e.g., Pinnacle, Vision, TerraPro) equipped with V-Mac IV engines. Interior Cabin Configurations: Manual covers engine systems relevant across different cabin designs. Cargo Payload Capacity: Not directly covered by engine manual, but engine power and torque are critical for payload capacity. Weights Gvwr: Not directly covered by engine manual, but engine specifications are a component of GVWR calculations. 🛡️ Safety Features Ratings Crash Test Data: Not applicable to an engine service manual. Active Features Engine Safety Features: ECM monitors and controls engine operation to prevent damage from over-speeding, overheating, and low oil pressure. Includes diagnostic alerts for safety-critical faults. Passive Features Engine Safety Components: Fail-safe modes for critical engine parameters, protective shutdown strategies. 💡 Technology Features Infotainment Infotainment System: Not directly related to the engine control module, but the V-Mac IV may interface with the truck's central diagnostic port for data retrieval. Driver Assistance Engine Performance Optimization: ECM controls features like cruise control, idle management, and can optimize engine response for fuel efficiency and power.
