➋ Design and manufacturing of the generators have both passedISO 9001 or ISO 9002 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 customers throughout the country24/7 after-sales service and technical support.

Performance Features

■ Cylinder bodyHigh-strength alloy cast iron construction, with excellent rigidity, minimal vibration, and low noise.

■ Cylinder HeadFour-valve design per cylinder, optimized airflowFuel mixture ratio, effectively improves combustion and emissions; one cap per cylinder, easy to maintain.

■ CrankshaftSingle camshaft can be precision Accurately control the valve and fuel injection timing; cam profiles can reduce shock forces, enhancing reliability and durability.

■ CrankshaftA solid crankshaft made of high-strength forged steel, with induction hardening on the rounded corners and shaft journals, ensures higher fatigue strength.

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