➋ Design and manufacturing units of the generator sets have passedISO9001 or ISO9002 Certification.

➌ Cummins offers1-year or 1000 operating hours warranty, covering the entire generator set including the engine, generator, and control system.

➍ Nationwide professional service network serving customers24/7 after-sales service and technical support.

Performance Features

■ Advanced design and exquisite manufacturing, adaptable to various stringent operating conditions, with high strength and strong load-bearing capabilities.

■ The cylinder block and cylinder head feature integrated design, eliminating the occurrence of engine water and oil leakage, with approximately 30% fewer parts than similar engines.40%, significantly reduced failure rate

■ The cylinder bore features a platform pattern honing design, which includes a geometric structure to prevent oil leakage. It also utilizes technologies such as piston ring components and sealed gasket rolled edges, reducing oil consumption.

■ Holesett with integrated exhaust bypass valveHolset turbochargers, with low-speed responsiveness and strong power delivery

■ Three-stage fuel filter ensures balanced particle distribution, protects the main components of the fuel system, and extends engine life.
