READ MOREProduct Advantages
Durability:
The 360KW Chongqing Cummins generator set features a high-strength integrated design for the engine block and cylinder head, providing greater overall rigidity and enhanced fatigue resistance. This effectively reduces mechanical wear from long-term operation, ensuring stable, long-lasting performance and excellent durability.
High Reliability:
Equipped with Cummins’ original PT fuel system, it includes an overspeed protection mechanism. The low-pressure fuel system design simplifies fuel lines, stabilizing the system and significantly reducing failure rates. Leveraging Cummins’ mature power system matching and overall engineering design philosophy, it maintains high stability and safety even under high-load operating conditions.
Excellent Performance:
The high-efficiency Cummins exhaust gas turbocharging system ensures sufficient air intake, improving engine combustion efficiency. The pressure-type pulse exhaust system fully utilizes exhaust energy for secondary energy recovery, significantly enhancing combustion quality. It delivers excellent fuel economy under both high-load and low-load conditions, effectively reducing specific fuel consumption.
The generator set provides high torque, strong power output, rapid transient response, and ample torque reserve, enabling it to adapt to sudden load changes while ensuring stable high-power output.
Easy Maintenance:
With a modular, fully integrated design, the system is compact and well-organized, making parts easy to disassemble and maintain. The platform’s standardized component design ensures high parts interchangeability, simple and efficient maintenance, and easy access to spare parts, significantly lowering operational costs.
Strong Adaptability:
The generator set delivers strong, stable power and fuel efficiency, suitable for various complex load scenarios. It has a wide fuel compatibility range and strong environmental adaptability, capable of stable operation in high temperatures, high humidity, extreme cold, and high-altitude conditions, meeting the requirements of multiple industries and applications.
