水介質能否替代發動機冷卻液？這是廣大瓦斯發生器用戶相對忽視的問題，小編說明了瓦斯發動機組冷卻劑的重要作用。

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.

瓦斯發動機正常工作溫度為65-70°，比普通的發動機要低15-20°，過高的發動機溫度會使混合氣體爆燃，影響發動機正常運轉同時會加速發動機油蛻變，使之產生積碳，容易形成油膜決裂，光滑不良，磨損加劇。因而，運用發動機冷卻液對瓦斯發動機停止恰當降溫尤為重要，能夠保證發動機正常工作。

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.

但假如發動機的溫度太低，冷卻過度，也會產生反作用，使發動機蓋的熱量損失加大，不利于可燃混合氣體的構成和熄滅，并招致發動機油粘度變大，摩擦損失增加，形成發動機有效功率降低。

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.

在實踐運用過程中，普通應用冷卻液的小循環和大循環處理瓦斯發動機的冷卻光滑問題，使發動機得到適度的冷卻，從而使其堅持在適合的溫度范圍內工作。通常關于瓦斯發動機的水冷卻系統，當缸蓋冷卻水套中的冷卻液溫度到達60°左右時，大循環啟動，可確保瓦斯發動機正常工作。

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.

在實踐運用中用戶常常疏忽發動機冷卻液的運用，而簡單的用水作為發電機組的冷卻介質。隨著發電機組的運轉冷卻水損耗嚴重，需求頻繁補加水分，且運用一段時間后就會結垢，招致發電機組冷卻效果降落，發動機運轉溫度升高，影響發電機組的正常發電。

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.
