Description
Technical field
The invention belongs to oil product technical field, and in particular to a kind of high definition test oil and preparation method thereof.
Background technology
When new car is offline, generally require to inject a certain amount of fuel oil, i.e. first charge of oil, because new car is from offline, to being sent to use
In the handss of family, it may be necessary to the long period, and vehicle sells to the area of Different climate condition, therefore just charge of oil may be in new car oil
The storage long time in case, and can suffer from high temperature, the test of severe cold area condition.If first charge of oil poor quality, stability
Difference, then be easy to the parts such as, generation colloid rotten in new car fuel system internal oxidition, blocking fuel screen, atomizer, causes to send out
Motivation failure.In addition, if vehicle is in severe cold area, due to oil product long-term frozen, vehicle may be difficult to start.Further, for a long time
The oil product of storage also easily corrodes fuel system, erosion blocking filter screen and atomizer, causes engine failure.
In addition, car manufactures or research and development institution need to make in automobile engine, car load research and development, test and internal demarcation
With test oil, the quality of test oil has considerable influence to the accuracy of test result.
Present inventor has found that existing diesel oil exists when using existing diesel oil as first charge of oil and test oil
It is inadequate as stability, cleannes, oxidation stability and low-temperature startup during first charge of oil, it is impossible to meet in different regions harshness ring
The requirement used under the conditions of border, and when as test oil, also because cleannes, oxidation stability are not enough, it is impossible to meet examination
Test the requirement with oil.
The content of the invention
In order to solve the problems referred to above of prior art presence, the invention provides a kind of high definition test oil and its preparation side
Method, the high definition test oil steady quality, cleannes are high, while having good oxidation stability and low-temperature startup, energy
Enough meet and used and test requirements document under harsh environmental conditions；The preparation method has the advantages that easy to operate, finished product is stable.
