Weichai high-efficiency energy-saving backup power supply 132KW diesel generator set

⚙️ I. Efficient Powertrain
High pressure common rail fuel technology

Adopting 1800bar high-pressure common rail injection system, the diameter of fuel atomised particles is ≤8μm, the combustion efficiency reaches 46.2%, and the fuel consumption rate under the rated working condition is as low as 195-198g/kWh, which reduces fuel consumption by 5-8% compared with similar products16.

Multi-stage injection control optimises the combustion process, with the lowest fuel consumption at 75% load (195g/kWh) and high efficiency at full load (205g/kWh)6.

Intelligent Speed Regulation and Response

Equipped with DSE8610 digital controller, the speed control accuracy reaches 0.25%, the transient response can restore the rated frequency within 5 seconds, and it supports automatic load distribution for multiple machines connected in parallel13.

🛡️ II. High Reliability and Durability
Reinforced structural design

The cylinder block is made of high-strength peristaltic cast iron (tensile strength ≥450MPa), the crankshaft is treated with ion-nitriding (surface hardness ≥700HV), and the key bolts are 12.9-grade high-strength fasteners14.

The ‘boat-shaped’ oil sump increases the oil heat dissipation area and improves the vibration damping performance4.

Multi-protection system

Real-time monitoring of oil pressure (＜0.15MPa shutdown), water temperature (＞105℃ alarm), vibration (＞7.1mm/s protection) to ensure safe operation1.

🌿 3. Environmental protection and low noise performance
Low emission technology

Equipped with DOC+DPF after-treatment system, it meets the off-road National III emission standards (NOx≤3.5g/kWh, carbon smoke＜0.025g/kWh).

Noise and Vibration Control

Through three-dimensional acoustic optimisation, the noise at 1m is ≤78dB(A), with double-layer impedance composite muffler, and the vibration intensity is <2.8mm/s.

🛠️ IV. Maintenance Convenience and Intelligence
Modular design

Fuel filter replacement ≤ 5 minutes, oil filter side mounted, control system equipped with quick-plug interface.

Intelligent diagnosis and remote management

Supports remote transmission of fault codes, life prediction of key components and AR-assisted maintenance guidelines.

⛰️ V. Environmental Adaptability
High altitude and extreme working conditions

No power attenuation at altitude of 3000m, power loss of only 5-7% at 4100m.

Wide temperature adaptability: -40℃ to 50℃ reliable start, fuel system compatible with 0# diesel and low quality fuel (two-stage filtration + water removal design).

Compactness

Size about 2470×930×1450mm, weight 1330-1550kg, smaller volume in the same power.

📊 VI. Fuel efficiency and load optimisation
Load ratio (%) Fuel consumption rate (g/kWh) Thermal efficiency (%)
25 235 36.2
50 205 41.5
75 ⭐️ 195 43.6
90 198 42.8
100 205 41.5
Source: Standard test conditions (25°C, 500m altitude).
Optimum load range: 70-85% for maximum efficiency; deviation from this range results in a 5-8% drop in efficiency.

💡 Summary
Weichai WP6D132E200, with its core advantages of efficient combustion, intelligent control, high reliability and low maintenance cost, is particularly suitable for data centres, manufacturing plants, high altitude areas and other scenarios that require continuous power supply. Its environmentally friendly (National III emission) and low-noise design also meet the sustainable development requirements of modern industry. For further verification of actual cases (e.g. 400 hours of trouble-free operation test) or after-sales service policy (nationwide joint warranty/1 year warranty), please refer to the manufacturer's technical documents.
