Product Description

Cummins on-highway diesel generator sets are designed, manufactured, and tested to Cummins' global standards, offering customers a reliable and integrated power generation system with superior performance under constant load, backup, and continuous operation conditions.

➊ CompliantISO 8528-2005 and GB/T 2820-2009 standards for "AC Generator Sets Driven by Reciprocating Internal Combustion Engines"

➋ The design and manufacturing units of the generator sets have both passedISO 9001 or ISO 9002 certification.

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

➍ A nationwide professional service network serving clients throughout the country24/7 after-sales service and technical support.

Performance Features

■ Advanced design and exquisite manufacturing, adaptable to various stringent working conditions, with strong high-intensity and heavy-load operation capabilities.

■ The cylinder block and cylinder head are designed integrally, effectively preventing engine water and oil leakage, with approximately 30% fewer parts than similar engines.40%, failure rate significantly reduced

■ The cylinder bore features a platform pattern honing design, with a geometric structure to prevent oil leakage. It also utilizes technologies such as piston ring assembly and sealing gasket rolled edge molding, which reduces oil consumption.

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

■ 3rd-grade fuel filter ensures balanced particle dispersion levels, protecting key components of the fuel system and extending engine lifespan.
