1. Technical Parameter

2. Product Features

The Cummins QSZ13-G5 360kW/450kVA diesel generator set is an upgraded high-power industrial generator launched by Dongfeng Cummins, built on the mature QSZ13 heavy-duty engine platform. As a mainstream 450kVA Cummins diesel generator widely used in industrial and engineering fields, this unit adopts XPI ultra-high pressure common rail fuel system and Coolpac integrated cooling design. It delivers stronger power output, more precise combustion control and lower operational noise, solving the problems of insufficient power margin and unstable operation of traditional same-level generator sets. With reliable field adaptability and long-duration load resistance, it has become a preferred power solution for medium and large-scale industrial standby power and off-grid main power projects.

2.1 Upgraded Electronic Control System, More Stable Power Output

Equipped with Cummins exclusive XPI ultra-high pressure common rail fuel injection system, the QSZ13-G5 engine supports multiple precision injection events with injection pressure up to 2400 bar. This advanced fuel control technology achieves finer fuel atomization and more sufficient combustion, effectively improving power conversion efficiency. The full-authority electronic dual-speed control system supports real-time load monitoring and intelligent fuel adjustment, ensuring stable frequency and voltage output even under frequent variable load conditions. Whether facing gradual load increase or instantaneous impact load, the 360kW prime power output remains stable without obvious fluctuation, which fully meets the high power quality requirements of automated production lines and precision electrical equipment.

2.2 Large Power Reserve, Strong Overload and Impact Resistance

This industrial diesel generator set is configured with 360kW continuous prime power and 400kW emergency standby power, with a very sufficient power reserve margin. Different from conventional generator sets with narrow power range, the QSZ13-G5 unit can withstand short-term overload operation and frequent load switching, and is not prone to shutdown or protection failure caused by sudden load changes. The matched turbocharged air-air intercooled intake system optimizes intake efficiency in high-temperature environments, ensuring stable power release even in long-term high-load operation. It can easily cope with the simultaneous start and operation of multiple high-power mechanical equipment, adapting to complex industrial load working conditions.

2.3 Integrated Structural Design, Higher Operational Reliability

The engine adopts high-rigidity alloy cast iron cylinder block and integral all-steel piston structure, with most auxiliary parts integrally cast on the cylinder block. This optimized structure reduces scattered external pipelines and connecting parts, effectively lowering the failure rate of pipeline aging, oil leakage and air leakage. The forged steel crankshaft and camshaft enhance the overall vibration resistance and pressure resistance of the unit, adapting to long-term uninterrupted operation and harsh field vibration environments. The supporting brushless self-excited alternator eliminates vulnerable carbon brush components, avoiding common faults such as carbon brush ablation and poor contact power failure, greatly improving the overall operational stability of the equipment.

2.4 High-Grade Protection Configuration, Adaptable to Complex Working Conditions

The alternator adopts H-grade ultra-high temperature resistant insulation material, which can resist long-term high-temperature aging and maintain stable insulation performance in high-temperature workshops and continuous high-load operation scenarios. The IP23 professional dustproof and waterproof protection grade can effectively block external dust, debris and splashing water, preventing internal circuit short circuit and mechanical damage caused by environmental erosion. The Coolpac integrated cooling package supports stable heat dissipation under 50℃ high ambient temperature, solving the overheating problem of ordinary generator sets in summer high-temperature operation. It can work stably in dusty mining areas, humid coastal environments and open-air construction sites all year round.

2.5 Low Noise and Low Emission, Better Comprehensive Performance

Benefiting from precise electronic combustion control and optimized structural vibration reduction design, the QSZ13-G5 generator set effectively reduces combustion noise and mechanical operation noise, with lower operating noise than traditional mechanical fuel injection generator sets of the same power. The optimized combustion strategy also reduces exhaust particulate and nitrogen oxide emissions, meeting Euro III and non-road national environmental protection standards. It is not only suitable for open industrial sites with low environmental restrictions, but also applicable for urban commercial and public facility power supply scenarios with strict noise and emission requirements.

2.6 Convenient Maintenance and Low Operational Cost

The modular integrated design simplifies the daily maintenance structure of the unit, with highly universal spare parts and strong interchangeability. The electronic control system supports intelligent fault self-diagnosis and data logging, helping maintenance personnel quickly locate faults and improve maintenance efficiency. The brushless alternator structure saves regular carbon brush replacement and maintenance work, reducing daily labor and material costs. Supported by Dongfeng Cummins’ nationwide after-sales service system, spare parts supply is sufficient and after-sales response is fast, effectively reducing later operation and maintenance costs and equipment downtime.

3. Application Scenarios

With its 360kW high stable power, strong overload resistance and excellent environmental adaptability, the Cummins QSZ13-G5 450kVA diesel generator set covers multiple high-standard power supply fields such as large industrial manufacturing, key engineering construction, commercial public facilities and emergency disaster relief. It can be used as both long-term main power supply for off-grid areas and emergency standby power supply for grid-connected facilities, with extremely wide market applicability and scene compatibility.

3.1 Large Industrial Manufacturing Standby Power

It is widely used as emergency backup power for large chemical plants, building material factories, mechanical processing bases, new energy factories and mining processing enterprises. Modern large-scale industrial production relies on continuous assembly line operation, and sudden grid power outage will cause production shutdown, material scrapping and huge economic losses. This high-power Cummins generator set can start quickly and realize automatic switching, providing uninterrupted power guarantee for production lines, frequency conversion equipment, workshop ventilation and fire protection facilities, ensuring stable and continuous industrial production.

3.2 Key Engineering & Mining Field Main Power Supply

It is the preferred main power supply equipment for municipal key projects, highway and bridge construction, railway infrastructure, open-pit mining, water conservancy projects and field geological exploration. Most remote construction sites and mining areas lack stable municipal grid coverage. The 360kW prime power of the unit can provide long-term stable power for large drilling machinery, hoisting equipment, mixing equipment, on-site office systems and construction personnel living facilities. Its high-strength vibration-resistant structure and high-temperature resistance can fully adapt to harsh outdoor working conditions such as wind, sand, humidity and high temperature.

3.3 High-Standard Commercial & Public Facility Backup Power

Suitable for large commercial complexes, five-star hotels, high-rise office buildings, comprehensive tertiary hospitals, campus facilities and government public institutions. These scenarios have dense personnel and involve key public service functions, requiring ultra-high power supply stability and safety. In case of sudden power outage, seasonal peak power restriction, grid voltage fluctuation and line maintenance, the 400kW standby power reserve of the unit can be quickly put into operation to ensure the normal operation of medical rescue equipment, fire protection linkage systems, elevator operation and lighting ventilation systems, avoiding public safety accidents and service interruption losses.
