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.

考慮到在高原條件下著火延遲的傾向，為了柴油發(fā)電機的運行經(jīng)濟性，一般推薦自然吸氣柴油機供油應(yīng)適當(dāng)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，動力性下降，排氣溫度上升，因此用戶在選用柴油發(fā)電機時也應(yīng)該考慮柴油機的高原工作能力，嚴格避免超負荷運行。

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.

根據(jù)近年來的實驗證明，對高原地區(qū)使用的柴油機，可采用廢氣渦輪增壓的方法作為高原的功率補償。通過廢氣渦輪增壓不但可彌補高原功率的不足，還可改善煙色、恢復(fù)動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、隨著海拔的升高，環(huán)境溫度亦比平原地區(qū)的要低，一般每升高1000M，環(huán)境溫度約要下降0.6攝氏度左右，外加因高原空氣稀薄，因此，柴油發(fā)電機的啟動性能要比平原地區(qū)差。用戶在使用時，應(yīng)采取與低溫起動相應(yīng)的輔助起動措施。

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，水的沸點降低，同時冷卻空氣的風(fēng)壓和冷卻空氣質(zhì)量減少，以及每千瓦在單位時間內(nèi)散熱量的增加，因此冷卻系統(tǒng)的散熱條件比平原差。一般在高原海拔地區(qū)不宜采用開式冷卻循環(huán)，可采用加壓的閉式冷卻系統(tǒng)以提高高原使用時冷卻液的沸點。

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.
