Description
Technical field
The invention belongs to petroleum products technical field, be specifically related to a kind of high definition test oil and preparation method thereof.
Background technology
When new car rolls off the production line, often need to inject a certain amount of fuel oil, i.e. first charge of oil, because new car is from rolling off the production line, to sending in user's hand, the long period may be needed, and the area of Different climate condition sold to by vehicle, therefore just charge of oil may deposit the long time in new car fuel tank, and may stand the test of high temperature, severe cold area condition.If just charge of oil poor quality, poor stability, be then easy to go bad at new car prime the fuel system internal oxidition, produce colloid, and parts such as blocking fuel screen, oil nozzle etc., cause motor fault.In addition, if vehicle is in severe cold area, due to oil product long-term frozen, vehicle may not easily start.Further, the oil product of long-term storage also easily corrodes prime the fuel system, and erosion blocking filter screen and oil nozzle, cause motor fault.
In addition, car manufactures or research and development institution need use-testing oil at motor car engine, car load research and development, test and inner timing signal, and the accuracy of quality to test result of test oil has considerable influence.
Present inventor is when using existing diesel oil as first charge of oil and test oil, find that existing diesel oil is inadequate as stability, degree of cleaning, oxidation stability and low-temperature startup during first charge of oil, the requirement used under the harsh environmental conditions of different areas can not be met, and when as test oil, also because degree of cleaning, oxidation stability are not enough, the requirement of test oil cannot be met.
Summary of the invention
