This series of generator sets is a high-power density, all-condition adaptable power solution launched by Weichai Power for global mid-to-high-end industrial, commercial, and infrastructure sectors. The core power utilizes Weichai's fourth-generation high-pressure common rail technology engines (WP4.1/WP6/WP10 series), with a standby power range covering 80-300kW and a prime power rating of 100-375kVA. The sets are designed in strict accordance with ISO 8528-5 and GB/T 2820-2009 international standards, natively compliant with EPA Tier 3, EU Stage IIIA, and China Non-Road Stage III emission standards, enabling seamless entry into major global markets like Southeast Asia, Africa, the Middle East, and Latin America without modification.
Through modular integrated design and the application of lightweight materials, the unit weight is controlled between 950-4200kg, with a minimum size of only 2900x1150x1650mm. They support three deployment modes: fixed installation, trailer mobility, and containerized configuration, adapting to diverse scenarios such as small and medium-sized equipment rooms, outdoor construction sites, and data center backup power rooms.

Supercritical Combustion Efficiency: Equipped with a 200MPa high-pressure common rail system, supporting 5-stage precise regulation (pre-injection, main injection, post-injection). Fuel atomization particle size ≤8μm, combustion efficiency increased by 19%. Minimum fuel consumption under rated conditions as low as 172g/kW·h (WP10 series), saving over 30% fuel compared to similar products.
Full Lifecycle Cost Advantage: Utilizes high-strength alloy cast iron cylinder block + forged steel crankshaft. Passed 1000-hour endurance test and 500-hour thermal shock test. Mean Time Between Failures (MTBF) ≥2500 hours, major overhaul interval up to 8000 hours. Operation and maintenance costs are 40% lower than competitors.
Dynamic Response Performance: Taking the WP10 series as an example, peak torque at 1000 rpm reaches 1200N·m, free acceleration time is only 1.2 seconds, enabling instant driving of high-inertia loads like air compressors and crushers, suitable for complex working conditions in mining and construction.

Low-Temperature Start | Intake air preheater + Low-temperature electronic control system | Starts within 8 seconds at -25°C |
High-Temperature Tolerance | 45°C copper water tank + Closed water circulation cooling system | Power retention rate ≥95% |
High-Altitude Adaptation | Three-stage turbocharger + High-altitude calibration | Power loss only 5%-7% at 4100m altitude |
Dust & Sand Protection | Three-stage 93% efficient dust filter + Fuel line self-cleaning system | Fuel line clogging failure rate reduced by 80% |
Fuel Compatibility | Two-stage fuel filtration + Water-separating fuel filter | Compatible with #0 diesel and low-quality fuels |
Voltage Regulation Accuracy: Matched with Weichai OEM brushless three-phase AC synchronous generator, equipped with an AVR automatic voltage regulation system. Steady-state voltage regulation rate ≤±0.5%, voltage fluctuation rate ≤0.3%, suitable for sensitive loads like data centers and medical equipment.
Multiple Safety Protections: Integrates six protection functions: low oil pressure, high water temperature, overload, under-voltage, phase loss, and short circuit. Supports ATS automatic switching (power restored within 10 seconds of mains failure). Automatic alarm and emergency shutdown upon fault detection.
Intelligent Early Warning System: Dual-backup ECU control modules (fault switchover time ≤0.2 seconds), equipped with vibration spectrum analysis fault early warning system. Fuel injector fault prediction accuracy reaches 92%, reducing overseas maintenance complexity.
The full series has passed certifications including CE, ISO 9001, SONCAP (Nigeria), SABS (South Africa), meeting European and American environmental standards and emerging market access requirements. Weichai engine particulate emissions are reduced by 80%, complying with EU Stage IIIA standards without the need for additional after-treatment devices, significantly reducing customer compliance costs.
