注意防止发动机温度过高。多数情况是水箱缺水,此时不可立即加入冷却水,否则会引起缸盖或缸体炸裂、烫伤人员。正确的做法是停止运行,低速运转,待水温降到70℃左右时,再慢慢加入清洁的冷却水。注意防止发动机水箱水垢过厚。发动机水套水垢过厚,会使散热效率降低30%~40%,易引起发动机过
Take care to prevent the engine temperature is too high. In most cases, the water tank is short of water, and cooling water can not be added immediately. Otherwise, it may cause the cylinder head or cylinder block to explode and scald. The correct approach is to stop running at low speed until the water temperature dropped to about 70 ℃, and then slowly add clean cooling water. Pay attention to prevent the engine water tank scale is too thick. Engine water jacket scale is too thick, will reduce the cooling efficiency of 30% to 40%, easily lead to engine over
