DaZe Power's High Altitude Diesel Generator Sets Technical Advantages

The core advantages of Dazai Power's high-altitude diesel generator sets lie in their intake supercharging, combustion and electronic control optimization, enhanced heat dissipation, low-temperature adaptability, and intelligent protection, achieving low altitude attenuation, high efficiency, and reliability. They are suitable for extreme working conditions at altitudes of 2,000 to 5,000 meters, with significantly superior comprehensive performance compared to ordinary sets. Below, we delve into the analysis from the perspective of key technologies:

Intake Turbocharging and Power Attenuation Resistance Technology

• Multi-Stage Boosting System

• The main models are equipped with Variable Geometry Turbochargers (VGT) and larger intercoolers, achieving power loss of less than 8% at 3,000 meters altitude, with a 15%-20% power retention improvement over standard turbines; for extreme high altitudes (>4,000 meters), optional dual-stage turbocharging is available, increasing intake pressure by 30%-50% while keeping power loss under 5%.

• The single-stage supercharger model exhibits only a 15% power drop at 3,000 meters, significantly outperforming conventional naturally aspirated units (approximately 30%), maintaining over 90% of the rated power within 1,500 meters.

• Enhanced Intake EfficiencyEnhanced intake manifold and air filter reduce intake resistance; increased intercooler efficiency lowers intake temperature by 10-15°C, further enhancing intake density and combustion efficiency.

Section II: Combustion and Fuel System Optimization

• High-pressure Common Rail + Intelligent Fuel InjectionHigh-pressure common rail precise control of fuel injection volume and timing, improved injectors reduce spray particle size by 10%, compatible with lean air, increasing combustion efficiency by 12%, and significantly reducing black smoke emissions.

• ECU High-Altitude Adaptive CalibrationThe built-in altitude compensation program automatically adjusts fuel injection and ignition timing, allowing for seamless adaptation to altitudes ranging from 2,000 to 5,000 meters without any manual intervention.

• High compression ratio designThe 19:1 compression ratio, combined with reinforced piston and valve components, ensures complete combustion even in low-oxygen environments, reducing carbon buildup and power loss.

• Fuel Compatibility and EconomyThe engine supports diesel from 0# to -35#, achieving an economical load fuel consumption of 200-230g/kW・h, a 15%-20% reduction compared to traditional models. A 50L fuel tank allows for continuous operation for 8-12 hours.

Enhanced Cooling and Thermal Management

• Thermal performance upgradeThe radiator surface area is increased by 20%-30% compared to standard models, featuring an intelligent variable speed silicone oil fan to tackle the cooling challenges posed by high altitudes and low air pressure.

• Low Temperature Protective SystemAdapted - Long-lasting antifreeze with 40℃ effectiveness, preventing freezing due to diurnal temperature differences; certain models equipped with low-temperature preheating systems, rapidly heating intake manifolds and cylinders for reliable cold starts.

Four: Low Temperature Startup and Environmental Adaptation

• Cold Start AssuranceOur specially designed low-temperature starter motor and battery, combined with intake pre-heating, can quickly start in -30℃ environments; the engine oil is formulated with a low-temperature-specific recipe to reduce friction losses during cold starts.

• Extreme operating conditions compatibilityKey components (piston rings, valves, and seals) are made of materials that withstand extreme temperatures, compatible with high-altitude strong ultraviolet radiation, strong sandstorms, and drastic temperature variations, featuring a low failure rate during continuous operation.

V. Smart Control and Security Protection

• Comprehensive Intelligent ProtectionEquipped with multiple protections including overload, short-circuit, under-voltage, over-temperature, and low oil level, it automatically shuts down in high-altitude environments to prevent damage.

• Remote and Automation FeaturesOptional remote control start and ATS automatic transfer switch; millisecond-level switching during power failure from municipal power, suitable for unmanned base stations, mines, and other scenarios.

• Enhancing ConvenienceModular design, universal for replaceable parts, and low maintenance costs; some models are equipped with a fault diagnosis system, enabling quick problem identification.

Part VI: Emissions and Reliability

• Environmental Emission ControlUtilizing technologies such as EGR+SCR, certain models meet the national IV emissions standards and can maintain stable control of NOx and particulate matter emissions even in high-altitude, low-oxygen environments.

• Long-term ReliabilityThe Qinghai-Tibet Railway and other projects have undergone field tests, demonstrating seamless operation for three consecutive months at an altitude of 4,500 meters. They are compatible with heavy-duty conditions in mining, infrastructure, and communication sectors.
