1. Due to the low air pressure, thin air and low nutrient content in the plateau area, especially for the naturally aspirated diesel generator, the combustion conditions become worse due to insufficient air intake, so that the diesel generator can not issue the original specified rated power. Even though the diesel generators are basically the same, the rated power of each type of diesel generator is different, so their ability to work on the plateau is different.

考虑到在高原条件下着火延迟的倾向，为了柴油发电机的运行经济性，一般推荐自然吸气柴油机供油应适当提前。

Considering the tendency of ignition delay under plateau conditions, it is generally recommended that the oil supply of naturally aspirated diesel engine should be properly advanced for the operation economy of diesel generator.

由于海拔升高，动力性下降，排气温度上升，因此用户在选用柴油发电机时也应该考虑柴油机的高原工作能力，严格避免超负荷运行。

As the altitude increases, the power decreases and the exhaust temperature increases, users should also consider the plateau working capacity of the diesel engine when selecting the diesel generator and strictly avoid overload operation.

根据近年来的实验证明，对高原地区使用的柴油机，可采用废气涡轮增压的方法作为高原的功率补偿。通过废气涡轮增压不但可弥补高原功率的不足，还可改善烟色、恢复动力性能和降低燃油消耗

According to the experimental results in recent years, the diesel engine used in plateau area can be compensated by exhaust gas turbocharging. It can not only reduce the fuel consumption and power consumption of the turbocharger, but also improve the power consumption of the turbocharger on the plateau

2、随着海拔的升高，环境温度亦比平原地区的要低，一般每升高1000M，环境温度约要下降0.6摄氏度左右，外加因高原空气稀薄，因此，柴油发电机的启动性能要比平原地区差。用户在使用时，应采取与低温起动相应的辅助起动措施。

2. With the increase of altitude, the ambient temperature is also lower than that in plain areas. Generally, for every 1000m increase, the ambient temperature will drop by about 0.6 ℃. In addition, due to the thin plateau air, the starting performance of diesel generators is worse than that in plain areas. When using, the user shall take auxiliary starting measures corresponding to low-temperature starting.

3.、由于海拔的升高，水的沸点降低，同时冷却空气的风压和冷却空气质量减少，以及每千瓦在单位时间内散热量的增加，因此冷却系统的散热条件比平原差。一般在高原海拔地区不宜采用开式冷却循环，可采用加压的闭式冷却系统以提高高原使用时冷却液的沸点。

3. Due to the increase of altitude, the boiling point of water decreases, the wind pressure and cooling air quality of cooling air decrease, and the heat dissipation per kilowatt in unit time increases. Therefore, the heat dissipation condition of the cooling system is worse than that of the plain. Generally, it is not suitable to use open cooling cycle in plateau altitude areas. Pressurized closed cooling system can be used to improve the boiling point of coolant in plateau use.
