因为汽油发动机和柴油发动机依靠不同的燃料运转,它们有不同的特点,因此对润滑油的性能要求也肯定相应不同。
Because petrol engine and diesel engine depending on the different fuel, they have different characteristics, so to the performance requirements of the lubricating oil must have corresponding different.
....柴油含硫量较高,燃烧后生成的酸性物质较多,需要机油的总碱值要较高;
柴油机工作时产生的高温积炭、烟炭较多,要求柴油机油的高温清净能力较强;而汽油机工作时产生的低温油泥的倾向较大,要求机油的低温分散能力较强;
因此,柴油发动机使用汽油机油或汽油发动机使用柴油机油是不可取的。API SL、SJ等汽油润滑油的性能级别都是以S开头(火花点火),而API CF、CD等柴油润滑油的性能参数都是以C开头(压缩点火),所以很容易把它们分开。级别为SJ/CF或 CF-4/SG的润滑油表示可汽柴两用,但S排在前面的,如SJ/CF表示首选用在汽油发动机内,C排在前面的,如CF-4/SG表示首选用在柴油发动机内。
... Diesel sulfur content is higher, the generated after combustion acid is more, need to oil the total base number of higher;
Diesel engine work produced when high temperature carbon deposit and soot is more, for diesel engine oil of high temperature detergency ability is stronger; And the low-temperature sludge generated by the engine work tend to be larger, requirements of engine oil low temperature disperse ability strong;
Therefore, diesel engine using gasoline engine oil or gasoline engine using diesel engine oil is not desirable. API SL, SJ gasoline lubricating performance levels are S (spark ignition) in the beginning, the API CF, CDS and other performance parameters of diesel oil are C (compression ignition) in the beginning, so it is easy to separate them. Level of SJ/CF/SG lubricating oil or CF - 4 said steam wood amphibious, but S at the top, like SJ/CF preferred in gasoline engine, C in the previous, such as CF - 4 / SG preferred to use in a diesel engine.
