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

➋ Design and manufacturing of the generators are both certified.ISO9001 or ISO9002 Certification.

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

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

Performance Features

■ Cylinder bodyManufactured from high-strength alloy cast iron, offering excellent rigidity, low vibration, and minimal noise.

■ Cylinder HeadEach cylinder features a four-valve design, optimized for air flowFuel mixture ratio, effectively improves combustion and emissions; each cylinder has its own cover, easy for maintenance.

■ CamshaftThe single camshaft allows for precise control of valve and fuel injection timing, with the cam profile reducing impact force, enhancing reliability and durability.

■ CrankshaftHigh A solid crankshaft made of high-strength forged steel, with induction hardening of the rounded corners and shaft journals, ensures enhanced fatigue strength.

■ PistonUtilizing advanced aluminum alloy casting technology,The omega-shaped head and bucket skirt design accommodates thermal expansion and contraction, ensuring a good fit.
