文档介绍：摘要
冷却液是汽车发动机不可缺少的一部分。它在发动机冷却系统中循环流动，
将发动机工作中产生的多余热能带走，使发动机能以正常工作温度运转。当冷却
液不足时，将会使发动机水温过高，而导致发动机机件的损坏。所以一旦车主发
现冷却液不足，应该及时添加。
冷却液，全称应该叫防冻冷却液，意为有防冻功能的冷却液，防冻液可以防
止寒冷季节停车时冷却液结冰而胀裂散热器和冻坏发动机气缸体，但是我们要纠
正一个误解，防冻液不仅仅是冬天用的，它应该全年使用，汽车正常的保养项目
中，每行驶一年，需更换发动机防冻液。
符合国家标准的冷却液，沸点通常都是超过 105℃，比起水的沸点 100℃，
冷却液能耐受更高的温度而不沸腾（开锅），在一定程度上满足了高负荷发动机
的散热冷却需要。

Abstract
The coolant is an indispensable part of the automobile engine. It circulate
in the engine cooling system to remove the excess heat generated from the
engine's work so that the engine can operate at normal working temperature.
When the coolant is insufficient, the temperature of the engine will be
overheated and the engine parts will be damaged. So once the owner finds
that the coolant is not enough, it should be added in time.
The cooling liquid, full name should be called antifreeze coolant for
cooling liquid with antifreezing function, antifreeze can prevent the cold
season when parking coolant freezes and splitting theradiator frozen and
engine cylinder body, but we must correct a misunderstanding, not only in
winter with antifreeze, it should be used throughout the year, maintenance
project the normal car, every year, need to replace the engine antifreeze.
The cooling liquid that accords with the national standard is usually over
105 degrees. Compared with the boiling point of water 100 degrees, the
coolant can tolerate higher temperature without boiling. It satisfies the
cooling and cooling requirement of high load engine to a certain extent.
Key words: coolant, boiling point, heat, flow, maintenance...
