The core power of this series utilizes Weichai's self-developed WP2.3/WP3.2 series high-pressure common rail engines. The prime power range covers 10-80kW, with standby power reaching 12.5-100kVA. It is specifically designed for global small and medium-sized commercial, agricultural, and outdoor construction scenarios. The units strictly comply with ISO 8528-5 and GB/T 2820-2009 standards, and natively meet EPA Tier 3, EU Stage IIIA, and China Non-Road Stage III emission requirements, allowing access to mainstream markets like Southeast Asia, Africa, and the Middle East without modification.
Region | Typical Scenarios & Needs | Weichai Core Value | Recommended Power |
Southeast Asia | Shop standby, agricultural processing (humid, cost-sensitive) | IP23 moisture-proof coating + compact design, land transport cost reduced by 70% | 10-30kW (WP2.3) |
Africa | Clinics, irrigation (poor fuel quality, difficult maintenance) | Fuel adaptability + 5000h overhaul cycle + local parts | 20-80kW (WP3.2) |
Europe & America | Villas, data centers (environmental, quiet) | EPA Tier 3 compliance + low noise + ATS automation | 10-50kW (WP2.3/WP3.2) |
Middle East | Desert construction sites, high-altitude base stations (high temp, dust) | High-temperature power retention ≥95% + dust-proof design + high-altitude adaptation | 50-80kW (WP3.2) |
Exceptional Thermal Efficiency: Equipped with Weichai's independent electronically controlled high-pressure common rail system, injection pressure reaches 180MPa. Combined with 5-time precise injection technology, it achieves a super-high thermal efficiency of 50.26%. Minimum fuel consumption at 100% load is 208g/kW·h, saving 8-12% fuel compared to similar products.
Long-Lasting Durability Design: Uses high-strength alloy cast iron cylinder blocks and forged steel crankshafts. Having passed 1000-hour endurance tests, the major overhaul cycle reaches 5000 hours, 20% longer than the industry average.
Low Noise Optimization: Pre-injection combustion technology + high-precision transmission gear train results in noise ≤85dB(A) under rated conditions, suitable for residential areas and noise-sensitive environments.
Low-Temperature Cold Start: Standard intake air preheater enables quick starts within 8 seconds at -25°C, meeting the needs of severely cold regions.
High-Temperature Power Retention: 45°C copper radiator + closed water circulation system improves heat dissipation efficiency by 30%. Power attenuation at high temperatures is ≤5%.
High Altitude and Dust Response: No power correction required up to 3000 meters altitude; power loss is only 5-7% at 4100 meters. Three-stage dust filter (filtration efficiency 99.9%) adapts to desert and mining environments.
Fuel Compatibility: Two-stage filtration + water separation filter design, compatible with low-quality diesel, addressing fuel quality variation pain points in emerging markets.
Compact Design: Whole unit weight 260-920kg, minimum size 1550x720x1080mm, 18% smaller in volume than same-power models. Supports multi-scenario deployment like wall-mounted and trailer-mounted.
Maintenance-Friendly: Open layout enables daily "maintenance without enclosure removal". Time for replacing three filters is reduced by 50%.
Global Parts Network: 15 parts centers established in regions like Africa and Southeast Asia. Parts cost is 40% lower than imported brands, with maintenance response time ≤72 hours.
Precise Voltage Regulation: Matched with Weichai's original brushless generator + high-precision AVR system. Voltage regulation rate ≤±1%, fluctuation rate ≤0.5%, meeting the needs of precision equipment.
Multiple Protections and Automation: Integrates five major protection functions (low oil pressure, high water temperature, overload, etc.). Supports ATS automatic switching (power restoration within 10 seconds of utility failure), enabling unmanned operation.
The full series holds certifications including CE, SONCAP, SABS. Particulate matter emissions are reduced by 80%, meeting standards without requiring after-treatment devices, significantly reducing customer compliance costs.
Weichai Global Service Network: Service outlets in 120+ countries and regions, response time in remote areas ≤72 hours.
Parts Supply System: 15 regional parts centers, delivery cycle for common parts ≤5 days.
Free Training Support: Multilingual manuals + video tutorials, on-site training available.
Original Factory Warranty Policy: Whole unit warranty 1 year or 1000 operating hours. Engine core components extended warranty up to 2 years.
