水介质能否替代发动机冷却液？这是广大瓦斯发生器用户相对忽视的问题，小编说明了瓦斯发动机组冷却剂的重要作用。

Can water replace engine coolant? This is a problem relatively ignored by the majority of gas generator users. The editor explained the important role of gas engine coolant.

瓦斯发动机正常工作温度为65-70°，比普通的发动机要低15-20°，过高的发动机温度会使混合气体爆燃，影响发动机正常运转同时会加速发动机油蜕变，使之产生积碳，容易形成油膜决裂，光滑不良，磨损加剧。因而，运用发动机冷却液对瓦斯发动机停止恰当降温尤为重要，能够保证发动机正常工作。

The normal working temperature of gas engine is 65-70 °, which is 15-20 ° lower than that of ordinary engine. Too high engine temperature will deflagrate the mixed gas, affect the normal operation of the engine, and accelerate the degeneration of engine oil, causing carbon deposition, easy to form oil film cracking, poor smoothness, and intensified wear. Therefore, it is particularly important to use engine coolant to properly cool the gas engine, which can ensure the normal operation of the engine.

但假如发动机的温度太低，冷却过度，也会产生反作用，使发动机盖的热量损失加大，不利于可燃混合气体的构成和熄灭，并招致发动机油粘度变大，摩擦损失增加，形成发动机有效功率降低。

However, if the temperature of the engine is too low and the cooling is too excessive, it will also have a reaction, which will increase the heat loss of the engine cover, which is not conducive to the composition and extinction of the combustible gas mixture, and cause the viscosity of the engine oil to increase, the friction loss to increase, resulting in the reduction of the effective power of the engine.

在实践运用过程中，普通应用冷却液的小循环和大循环处理瓦斯发动机的冷却光滑问题，使发动机得到适度的冷却，从而使其坚持在适合的温度范围内工作。通常关于瓦斯发动机的水冷却系统，当缸盖冷却水套中的冷却液温度到达60°左右时，大循环启动，可确保瓦斯发动机正常工作。

In the process of practical application, small circulation and large circulation of coolant are commonly used to deal with the problem of smooth cooling of gas engine, so that the engine can be moderately cooled, so that it can work within a suitable temperature range. Generally, for the water cooling system of gas engine, when the coolant temperature in the cylinder head cooling water jacket reaches about 60 °, the large cycle starts, which can ensure the normal operation of gas engine.

在实践运用中用户常常疏忽发动机冷却液的运用，而简单的用水作为发电机组的冷却介质。随着发电机组的运转冷却水损耗严重，需求频繁补加水分，且运用一段时间后就会结垢，招致发电机组冷却效果降落，发动机运转温度升高，影响发电机组的正常发电。

In practice, users often neglect the use of engine coolant, and simply use water as the cooling medium of the generator set. With the serious loss of cooling water in the operation of the generator set, it is necessary to add water frequently, and it will scale after using for a period of time, causing the cooling effect of the generator set to decline, and the operating temperature of the engine to rise, affecting the normal power generation of the generator set.
