INTRODUCTION

Special environmental conditions typically refer to high-temperature, low-temperature, and high-altitude environments. Each of these conditions presents distinct challenges to the performance and reliability of diesel generator sets.

In low-temperature environments (specifically below –10°C), the viscosity of fuel increases, reducing its evaporation and atomization capability. This results in a poorer combustible mixture and incomplete combustion, leading to a decline in output power, higher exhaust gas concentration, and increased emissions. Additionally, at low temperatures, lubricating oil thickens, diminishing its lubricating efficiency and increasing friction among moving parts. This raises starting torque and places greater stress on the engine during startup. Frequent cold starts under such conditions can significantly shorten the service life of the diesel engine.

In high-altitude (plateau) environments, the main challenges for diesel generators are reduced atmospheric pressure and lower temperatures, with atmospheric pressure having the most significant impact on engine performance. Lower air density leads to decreased engine power output and higher fuel and oil consumption, while also increasing thermal load on the engine. These factors directly affect both the generator's power capacity and key electrical parameters. Additionally, high levels of ultraviolet radiation, dry air, and elevated dust concentrations in high-altitude regions can further influence the generator’s operation and maintenance needs.

To address these demanding conditions, we have implemented a series of specialized design modifications to ensure reliable performance and adaptability in challenging environments.

TECHNICAL PERFORMANCE

1. Low-Temperature Adaptability
2. Protection Against High Humidity
3. Accurate High-Altitude Performance Correction

CUSTOMIZED SOLUTIONS

1. For High-Temperature Environments: We enhance heat dissipation by upgrading the radiator system and integrating additional fuel and lubricant coolers. Additionally, key heat-generating components—such as the exhaust pipe, flexible vibration-damping sections, and muffler—are fully insulated and enclosed within the generator housing to minimize thermal impact on surrounding equipment.
2. For Extreme Cold Conditions: Engine protection is ensured through integrated heating systems for the intake air, lubricating oil, engine coolant, starting battery, and fuel. This guarantees reliable starting and stable operation in sub-zero temperatures.
3. For High-Humidity Environments: The control cabinet and alternator are equipped with space heaters to prevent condensation and moisture buildup. The engine and alternator are also treated with specialized anti-corrosion coatings to protect against rust and electrical degradation.
4. For High-Altitude Applications: We apply necessary power derating corrections to both the engine and alternator to maintain performance under low atmospheric pressure. Specially designed radiators and cooling systems are used to accommodate reduced air density. For installations above 3,500 meters, electrical components rated for high-altitude operation are installed to ensure reliability and safety.
