Embodiment Construction

[0011] see Figure 1-4 , the present specific embodiment adopts following technical scheme: its performance analysis is as follows: 1, viscosity changes, and viscosity is the characterization of oil product internal friction, also is the index that represents oil product oiliness and fluidity. During the use of oil products, due to oxidation or soot (coal) ash pollution, the oil quality decays and the viscosity changes, and the viscosity generally tends to thicken. from figure 1 Judging from the viscosity changes of some of the listed test cycles, the viscosity change rate is not large, and the viscosity at 100°C is still within the quality index range of 15W-40 viscosity grade. The test oil is a multi-grade oil, and the fifth type of base oil is added to the oil. That is, polyol esters, used in heavy-duty large diesel vehicles, the oil viscosity does not change much, and the oil pressure is quite stable during use. On the one hand, it shows that the oil is not deeply oxidize...

Abstract

The invention provides a performance analysis experiment of internal combustion engine oil, and relates to the field of internal combustion engine oil technology. The performance analysis is as follows: (1) viscosity change; (2) changes of acid value and total base number; (3) differential infrared spectroscopic analysis result; (4) spot dispersibility test; (5) metal content, which can prolong vehicle maintenance time for durability, thereby the vehicle has long operation time and strong practicality.

Description

technical field [0001] The invention relates to the technical field of internal combustion engine oil, in particular to a performance analysis experiment of 15W-40CI-4 / SL internal combustion engine oil. Background technique [0002] In order to gradually realize the localization of oil for mining equipment, anti-wear hydraulic oil (completed in 12 years) and GL-5 heavy-duty vehicle gear oil (11 Based on the 3,000-hour real-vehicle use test completed in 2013, an 8,000-hour real-vehicle use test of 15W / 40CI-4 / SL internal combustion engine oil was completed on the Haulpak170D extra-large vehicle from the end of 2012 to March 2013. [0003] The performance of 15W-40CI-4 / SL internal combustion engine oil has not been analyzed. Contents of the invention [0004] The purpose of the present invention is to provide a performance analysis experiment of internal combustion engine oil, which can extend the maintenance time of the vehicle, is relatively durable, has a long running tim...
