Product Description

Cummins on-highway diesel generator sets are designed, manufactured, and tested to Cummins' global standards, providing customers with a reliable integrated power system that performs exceptionally well under normal load, standby, and continuous operation.

➊ MeetsISO 8528-2005 and GB/T 2820-2009 Standards for "AC Generating Sets Driven by Reciprocating Internal Combustion Engines"

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

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

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

Performance Features

■ Advanced design and exquisite craftsmanship Adaptable to stringent operating conditions, boasts high strength and robust load-bearing capacity.

■ Holset Exhaust Bypass Valve Better dynamics.

■ Integrated design Cylinder block, cylinder head, and other components are "multi-functional," reducing fasteners and featuring 40% fewer parts than similar engines, significantly lowering the failure rate.

■ Superior reliability Forged steel camshaft and crankshaft, high-strength cylinder block design, high rigidity, excellent high-pressure resistance, and extended service life.

■ Platform pattern honing design cylinder sleeve Effectively prevents oil leakage with a perfect geometric structure.

■ Rotor High-Pressure Fuel Pump Lower fuel consumption and effectively reduce noise.
