Automotive Industry: How good or bad a comprehensive assessment of the quality of lubricating oil?

Physical and chemical indicators are based on the basic performance of the lubricating oil as a measure of physical and chemical indicators comprising: a kinematic viscosity, a low temperature dynamic viscosity, viscosity index, flash point, pour point, sediment, water, foaming, carbon residue, and the value of sulfated ash and various elements of content and so on. These physical and chemical indicators only measure basic indicators of lubricants, even if the physical and chemical indicators are substandard, the simulation test bench behind and going.

    Simulation test is the preferred method of assessment, the first simulation, the oil in the research and development process, the technician discovered the oil can not explain the physical and chemical indicators do not reflect problems in the use of mechanical friction is easy to use, the main test has the following components: coke plate heat pipe test methods and test methods reflect the dispersion of clean motor oil and anti-oxidation; reflect Vehicle test methods and multi-metal oxide thin film oxidation test method for lubricating oil under high temperature oxidation capacity; reflects the ability of the car spot test method sludge dispersion lubricants; reflect the level of anti-wear motor oil temperature four-ball machine wear test methods. These simulations can simply reflect the work of the engine, especially not simulate combustion performance of the engine for oil in complex situations and working conditions. In addition, the simulation test methods commonly used to strengthen or inductive comparison of test conditions. However, beneath the real will strengthen because the whole process of the engine operation, the combination of factors combine to affect the oil's antioxidant, clean, decentralized and wear resistance, it is impossible simulation performance evaluation of the individual evaluation method truthfully out, so the simulation test methods and evaluation index is basically not reflected in the engine oil specification standard. In order to reflect a more realistic problem bench true reflection of the oil usage, while the manufacturing sector has also been recognized by the engine, but also developed a performance evaluation of lubricants bench. Bench is the representative of the engine installed in the test chamber, the test to be assessed under a certain time endorsed or certified under controlled conditions and in accordance with the engine manufacturer before the performance indicators set by the test we negotiated, such as Taiwan After completion of the test stand to be judged; observation can test the oil meets the requirements; determine if its oil targets are within limits, it can be considered that the oil obtained preliminary approval, and pass this type of level of oil card. In principle, you can supply the market. After the above three tests, the quality of lubricating oil can be completely assured, is consistent with the various engine manufacturers for engine oil needs.
