Firstly,
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 diesl 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.
