1、机油特性:粘度、粘度指数、闪点。当指数为100时,温度为40℃,粘度为100,温度为100℃,粘度为20.指数越高,粘度及温度影响越小;指数越低,粘度受温度影响越大。机油要有适当的粘度,粘度是机油性质的重要指标及使用性能依据,如粘度太小,在摩擦零件受压的情形下,机油就会从摩擦面压出,形成干摩擦或半干摩擦;若粘度过大,流动性差,难以进入摩擦表面的间隙中,还会增大摩擦力,影响内燃机功率,同时使内燃机起动困难。内燃机是在高温状态下工作,机油粘度变化越小越好。
2、机油内不应含对金属有腐蚀作用的酸碱性物质,会使金属表面生锈。
3、机油应不易燃烧,当机油进入燃烧室时,燃烧后的粘度越小越好。
4、进口柴油发电机组要求使用美孚、壳牌15W-40CF进口机油。

The use of diesel generator sets cannot do without engine oil. Do you know the requirements for the use of engine oil in diesel generator sets? Friends who are still unclear, come and listen to the introduction of the generator set manufacturer!

1. Oil characteristics: viscosity, viscosity index, flash point. When the index is 100, the temperature is 40 ℃, the viscosity is 100, the temperature is 100 ℃, and the viscosity is 20. The higher the index, the smaller the influence of viscosity and temperature; The lower the index, the greater the influence of temperature on viscosity. Engine oil should have an appropriate viscosity, which is an important indicator of its properties and a basis for its performance. If the viscosity is too low, under pressure on the friction parts, the engine oil will be pressed out of the friction surface, forming dry or semi dry friction; If the viscosity is too high and the fluidity is poor, it will be difficult to enter the gaps of the friction surface, increase the friction force, affect the power of the internal combustion engine, and make it difficult to start the internal combustion engine. Internal combustion engines operate at high temperatures, and the smaller the change in oil viscosity, the better.

2. The engine oil should not contain acidic or alkaline substances that have a corrosive effect on metals, as they can cause rusting on the metal surface.

3. Engine oil should not burn easily. When the engine oil enters the combustion chamber, the lower the viscosity after combustion, the better.

4. Imported diesel generator sets require the use of Mobil and Shell 15W-40CF imported engine oil.
