Dear experts, what are the factors that affect the wear mark diameter of diesel fuel used in vehicles meeting National VI standards, and what should be the appropriate amount of anti-wear additive to use? We are manufacturers of additives; sometimes, even when the anti-wear additive is added at around 280 ppm, the product still fails to meet the standards. Why is that? Is it necessary to add a mixer after adding the admixture to improve mixing?
Diesel: Sulfur content ≤1.5 ppm; polycyclic aromatic hydrocarbons ≤3; monocyclic ones ≤12
The addition amount on our end has been no less than 400PPM recently, and this is related to the properties of the raw materials, the degree of reaction, and the quality of the modifying agents
Does diesel acidity have an impact? Could we discuss this in more detail?
