①发动机功率下降和燃油消耗增加。由于海拔高，空气密度和压力降低，发动机的充气量、气缸压缩压力和温度也随着降低，致使混合气过浓，引起燃烧不良冒黑烟。此种情况，可通过调整的办法解决，即调整喷油泵，减少供油量，直到排气不冒黑烟为止。
Engine power decreases and fuel consumption increases. Due to the high altitude, the air density and pressure decrease.The engine's charge, cylinder compression pressure and temperature also decrease, causing the mixture become too thick and causing poor combustion and black smoke. This situation can be solved by adjusting the fuel injection pump to reduce the fuel supply until the exhaust does not smoke
②调整供油提前角。海拔高度一般在2000一3000米时，可提前1°－2°，在3000-4000米时，可提前2°－4°。
Adjust the fuel supply advance angle. When the altitude is generally between 2000 and 3000 meters, it can be advanced by 1°-2°. When it is 3000-4000 meters, it can be advanced by 2°-4°.
③蓄电池容易失效。由于水的沸点降低，故蓄电池的电解液中的水分容易蒸发，使液面降低，影响蓄电池的正常工作，因此应经常检查蓄电池液面的高度，及时补充蒸馏水。
The battery is prone to fail. As the boiling point of water decreases, the water in the battery is easy to evaporate, lowering the liquid level and affecting the normal operation of the battery. Therefore, the height of the battery liquid level should be checked frequently and should add distilled water in time.
