25mm
以上，同时避免从油箱底部出油，以防
水分及杂质进入柴油机的燃油系统。
 The fuel suction port in the fuel tank shall be away from the tank bottom for over
25mm to avoid the fuel out of the bottom and to prevent water and impurities entering
in the fuel system of the diesel engine.

冷却液的使用：
Application of cooling fluid
n
如使用水做为冷却液，应采用清洁干净的软水，不能使用井水、河水、泉水等硬水。
If water is used as coolant, clean soft water shall be adopted, it is forbidden to use well water,
river water, spring water and other hard water.
n
常用的硬水软化方法是煮沸沉淀后除去沉淀物。更为彻底的方法是硬水中加软化剂，如每
升水加 0.5 ～ 1g 碳酸氢钠（纯碱）或 0.5 ～ 0.8g 氢氧化纳（烧碱）。
Water softening method in common use is to boil water and remove precipitates after
precipitating. Most thorough method is to use water softening agent, e. g. add 0.5
～
1g
sodium bicarbonate (calcined soda) or 0.5
～
0.8g sodium hydroxide (sodium hudroxide) for
every liter of water.
n
建议使用防冻液做为冷却液，特别是使用环境温度较低、海拔高度较高时。防冻液具有防
冻、防腐蚀 、防穴蚀、防垢、高沸点等功能。
It is recommended to use antifreeze as coolant, especially in the environment of low
temperature and high elevation. Antifreeze takes the advantages of freeze resistance,
corrosion prevention, cavitation pitting prevention, anti-scale prevention and high boiling
point.
n
优质的防冻液是国家指定的检测站检测合格的品牌，从外观上看
:
清澈透明、无杂质、不浑
浊、无刺激性气味，产品外包装上应有详细的生产单位名称，产品说明书以及明确的指标说明。
