Product Description

Cummins On-Highway diesel generator sets are designed, manufactured, and tested to Cummins' global standards, providing customers with a reliable, integrated all-in-one power generation system that excels in continuous, standby, and peak load operations.

➊ Meets the ISO 8528-2005 and GB/T 2820-2009 standards for "AC Generating Sets Driven by Reciprocating Internal Combustion Engines."

➋ The design and manufacturing units of the generator sets have both passed ISO9001 or ISO9002 certification.

➌ Cummins offers a 1-year or 1000-hour runtime warranty, covering the entire genset for engine, generator, and control system warranty.

➍ A nationwide professional service network provides 24/7 after-sales service and technical support to customers.

Performance Features

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

■ Holset Exhaust Bypass Valve Enhanced dynamics.

■ Integrated design Cylinder block, cylinder head, and other parts are "one for many," reducing connecting components. These parts are 40% fewer than those of similar engines, significantly lowering the failure rate.

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

■ Platform pattern honing designed cylinder sleeve Effectively prevents oil leakage with perfect geometric construction.

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