一防发动机温度过高　夏季气温高,影响发动机的功率。在使用中若遇发动机“开锅”,多数情况是水箱缺水,但此时切不可立即加入冷却水,否则会引起缸盖或缸体炸裂。正确的做法:停止运行,低速运转,待水温降到70℃左右,再慢慢加入清洁的冷却水。超负荷作业,不但水温升高很快,而且容 An anti-engine temperature is too high Summer high temperature, affecting the engine power. In case of engine in case of “boil”, in most cases the water tank water shortage, but this time must not be immediately added to the cooling water, otherwise it will cause the cylinder head or cylinder burst. The correct approach: stop running, low-speed operation until the water temperature dropped to about 70 ℃, and then slowly add clean cooling water. Work overload, not only the water temperature rises quickly, but also capacity
