沃尔沃 D7D Engine

Powerful Low-Speed, High-Torque Output: Specifically tuned for the earthmoving demands of excavators and loaders, the engine delivers massive peak torque at a low speed of just 1,350 rpm. This ensures exceptionally stable power delivery during heavy-duty tasks—such as excavating or prying massive boulders—effectively preventing engine stalling or RPM drops under load. Intelligent Electronic Diesel Control (EDC) System: Equipped with Volvo’s advanced EDC module and high-pressure unit pump technology, the system precisely adjusts fuel injection quantity and timing within milliseconds based on hydraulic load demands. This maximizes power output while minimizing fuel consumption. Exceptional Durability and Ease of Maintenance: Features a high-strength alloy cast iron cylinder block for superior structural robustness. Built on a mature architecture shared with the Deutz 1013 series, the engine offers high parts interchangeability and global availability, significantly reducing maintenance costs over the equipment's lifecycle.
