DOT3和DOT4型制动液失效的影响因素探究

Study on Influence Factors of DOT3 and DOT4 Type Brake Fluid Failure

目前人们对于汽车的需求量在不断增加,但对于车用油品的了解达不到标准,许多人对制动液是否失效和更换存在盲区。文章主要通过分析时间,水分和混油对其ERBP,p H和运动粘度的影响,确定相关失效点。通过实验分析得出,时间对制动液的影响在相关性质指标范围内,加入2.5 m L去离子水,加入10%的汽机油和20%ATF220都为相应制动液的失效点。

At present, people＇s demand for cars is increasing, but the understanding of the car＇s oil is not up to the standard, many people have a blind spot on the brake fluid failure and replacement. This paper mainly through the analysis of time, water, mixed oil on the impact of its ERBP, pH and kinematic viscosity, determine the relevant failure point. Through the experimental analysis, the influence of time on the brake fluid in the range of related properties, adding 2.5mL de ionized water, adding 10 % of the steam engine oil and 20 % ATF220 are the corresponding brake fluid failure point.
