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

•Cummins' patented PT fuel system, ultra-high injection pressure, to ensure good engine atomization and full combustion.

• The efficient Holset exhaust gas turbocharger has full air intake, improving efficiency, further improving combustion, and reducing engine fuel consumption.

• Air-air cooling technology ensures fuller air intake and better fuel economy.

• Replaceable wet cylinder liner with good heat dissipation effect and easy replacement.

• All model parts are highly versatile, highly serialized, and easy to maintain.

• The cylinder block and cylinder head adopt built-in pressure lubrication oil channel, which has a compact structure and low failure rate.

• Composite oil filter, easy maintenance, reduce daily maintenance costs.
