Product Description

• Cummins Low Noise Series diesel generator sets adopt Cummins' global uniform design, production and testing standards to provide customers with reliable, integrated integrated power generation systems with excellent performance during normal load, standby and continuous operation.

• Comply with ISO8528-2005 and GB/T2820-2009 * Alternator Sets Driven by Reciprocating Internal Combustion Engines".

 • The design and manufacturing units of the generator sets are certified by ISO9001 or ISO9002.

Cummins provides a 1-year or 1000-hour warranty and is responsible for the entire generator set warranty, including the engine, generator and control system.

•Professional service network throughout the country provides customers with 24-hour after-sales service and technical support.

 Performance characteristics

• Extended stroke The expansion of combustion gas is more sufficient, increasing the effective power output and ensuring low fuel consumption under strong power

• Advanced 4-valve structure has more horsepower, more thorough air combustion, low fuel consumption, and at the same time increases low-speed torque, good power and high work efficiency

• Articulated piston with forced cooling can withstand extremely high mechanical and thermal loads with good strength

• Enhanced cylinder block design Low noise and low vibration

• The center arrangement of injectors and symmetrical combustion chambers makes the mixture in the cylinder more uniform and the combustion more sufficient

• Advanced design The liter power ratio can reach 30.0kW/L, the machine structure is reasonable, and the maintenance is more convenient
