➋ The design and manufacturing units for the generators have all passedISO9001 or ISO9002 Certification.

➌ Cummins offers1-year or 1000 operating hours warranty, covering the entire 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

■ Lubrication System: All moving parts are under forced lubrication; a gear pump supplies pressurized lubricant to lubricate and cool the piston.
■ Fuel System:PT Fuel Pump, optimizes combustion, powerful performance; STC step timing ensures better full-load operation; utilizes low-pressure fuel supply, equipped with a fuel unidirectional loop, safe and reliable.
■ Cooling System: Gear-driven centrifugal pump for forced water cooling, large flow water channels, excellent cooling effect; water filter and specialized Please provide the Chinese content that you would like translated into American English.DCA additives effectively control the acidity of coolant.
■ Intake and exhaust system:Holset turbochargers enhance combustion; pressure pulse turbochargers fully utilize exhaust energy for increased efficiency; air-to-air intercooling ensures better fuel economy and emissions.
