Water cooled direct injection series commonly used diesel generator sets

⚙️ I. Core Performance Parameters
Power output

Rated power: 56 kW (about 75 hp), the maximum power can reach 62 kW, and the output electric power is 50 kW after supporting generator.

Overload capacity: supports 110% load operation, adapting to the sudden increase of power demand.

Fuel efficiency: Fuel consumption rate under load ≤ 258.4 g/(kW-h), some optimised models can be as low as 238 g/(kW-h), outstanding energy saving.

Operation Stability

Voltage/frequency adjustment accuracy: steady state voltage adjustment rate ≤±0.5%, frequency adjustment rate ≤±2%; transient fluctuation control (voltage ≤±15%, frequency ≤±10%) and fast recovery (voltage stabilised within 1 second, frequency within 3 seconds).

🔧 II. Structural design features
Engine technology

Four-stroke turbocharging: four-cylinder in-line design, bore × stroke 105 × 125 mm, displacement 4.33 L. Enhance intake efficiency and plateau adaptability through turbocharging.

Cooling and lubrication: Closed inner-circulation water-cooling system, equipped with 16L large-capacity oil tank, to ensure heat dissipation in long-time operation.

Low noise and emission reduction: industrial-grade muffler and optimised combustion design reduce noise and emission to meet environmental protection requirements.

Matching Generator

Brushless self-excitation system: with AVR (automatic voltage regulator) to achieve output voltage 400V/230V three-phase four-wire system, power factor 0.8.

Protection level: IP23 protection, H class insulation, suitable for high temperature and dust environment.

📊 III. Supporting application characteristics
Intelligent control system

Support full-automatic start-stop: 0-30 seconds delayed self-start after utility power failure (success rate 99%), automatic cooling shutdown after power supply recovery (delay 0-300 seconds adjustable).

Multiple protection functions: covering overspeed, high water temperature, abnormal voltage (overvoltage/undervoltage/overcurrent), start failure and other fault alarms.

Compact & Portable

The unit size is about 1800×710×1120 mm, weight 750-800 kg, supporting mobile power station or fixed installation.

🌍 Fourth, the use of environmental adaptability
Altitude and temperature: standard working conditions apply to altitude ≤ 1000 m, ambient temperature ≤ 40 ℃, over the required power correction.

Multi-field application:
✅ Backup power: emergency power supply for hospitals, schools, communication base stations and other critical facilities;
✅ Engineering power: power source for water pump units, crushers, fire-fighting equipment, marine machinery;
✅ Field operation: mobile power supply for construction sites, mining areas and other gridless scenarios.

🛠️ V. Quality and Service Guarantee
Certification and Warranty: Pass ISO9001, CE and other certifications, provide 12-month warranty, some manufacturers support global joint warranty.

Maintenance Convenience: Modular design simplifies daily maintenance, and filters (oil, diesel, air) are replaced as a whole to reduce maintenance difficulty.

💎 Summary
ZH4105ZD diesel generator takes high reliability, low fuel consumption and intelligent control as its core advantages, and is suitable for industrial and emergency scenarios that require continuous and stable power supply. Its turbocharged design strengthens the power output and environmental adaptability, while the compact structure with automatic control system improves the operation convenience. When selecting, it is necessary to pay attention to the altitude power correction and specific working conditions to optimise the use of efficiency.
