How to Choose Cummins Engine Lubricating Oil Correctly
by Starlight Generator dieselgeneratortechFirstly, when
choose engine lubricating oil, can not choose and know about engine lubricating
oil correctly.
As we know, about
vehicle diesel engine oil, we should choose different grades of oil according
to different types of diesel engines and different operating conditions. While,
for different proportion of additives, grades of diesel oil is also different.
For example, CC diesel engine lubricating oil and CD diesel engine lubricating
oil.
While manufacturers
produce diesel engine lubricating oil according to different brands of diesel
engine and demands, forming their own formulation systems in the formulation
process .
Lubricating oil is made
by base oil and additives. Although the quality of lubricating oil depends
mainly on the base oil, additives also can not be ignored. In the daily use of
lubricating oil, because the different brands of lubricating oil produced by
different manufacturers are mixed together to use, it is chemical reaction
between additives, resulting in serious deterioration of lubricating oil, loss
of the value of lubricating oil, resulting in engine damage.
In addition, when use
and choose lubricating oil, users maybe have some mistakes, as follows:
1.Some users think that
the clearer the oil is, the better the quality of the oil will be, if
lubricating oil becomes black, the quality is not good. In fact, if engine
lubricating oil becomes black, it is the dispersants and detergents in the oil
that act to disperse and dissolve the carbon deposited on the inner wall of the
engine and the colloid. If the diesel engine oil always does not blacken, on
the contrary, there is a problem with additives in the oil;
2.Some users choosing
lubricating oil do not accord to the grades recommended or required in the
manufacturer's instructions, while blindly pursue the consumption viewpoint of
famous brand, "the more expensive the price, the better the quality".
As a result, the oil used differs greatly from the requirements of the
manufacturer, which eventually leads to engine damage;
3.There are various
auxiliary additives for anti-wear of lubricating oil on the market, but in the
absence of the specifications, additives should not be added to the oil at
will.
How to select engine
lubricating oil correctly?
We should strictly
select the prescribed grade lubricating oil according to the use requirements
of diesel engine and working environment, and strictly prohibit the use of
inferior lubricating oil. In addition, when lubricating oil is used, the same
brand of lubricating oil should be selected. When non-same brand of lubricating
oil is selected, the lubricating oil in diesel engine should be exhausted and
cleaned with diesel oil before other brand of lubricating oil can be replaced.
The quality of engine
lubricating oil in use will ceaselessly decline, to a certain extent, it should
be replaced. If the lubricating oil is found to be thinner or thicker, or to be
stratified or precipitated, it must be changed even if it is not in the oil
changing period.
The viscosity of
lubricating oil has a great influence on the reliability and durability of
diesel engine. It is necessary to select suitable oil to ensure the normal
operation of diesel engine. Viscosity is too small, engine oil pressure is low,
oil film can not be maintained in the lubricated parts, loss of lubrication
effect, light cause serious wear and tear on the friction surface, heavy cause
serious accidents such as cylinder pulling, tile burning, axle holding, etc.
Viscosity is too high, cold start of engine is difficult, oil pressure is high,
but oil flow is slow, and can not reach the lubrication part, so wear
increases. In addition, high oil viscosity and high friction resistance will
lead to insufficient output power and increase fuel consumption.
In a word, we should
choose lubricating oil according to the instructions of Cummins diesel generator.
Hope this article can help you to use engine lubricating oil correctly.
