What is lubricity additive?
Lubricity additives are used in diesel fuel to reduce wear on engine components, particularly the fuel pump, to prevent break-down of the engine. With the advent of Ultra-Low Sulphur Diesel, lubricity additives became a requirement in most fuels to meet the ASTM D975 specifications for diesel.
What is lubricity in diesel?
Overview. The term lubricity is often defined as the ability of a lubricant—in this case diesel fuel—to minimize friction between and damage to surfaces in relative motion under load. Generally the tests used to evaluate diesel fuel lubricity try to create conditions of boundary lubrication.
What is the meaning of lubricity?
ability to lubricate; capacity for lubrication: the wonderful lubricity of this new oil. instability; shiftiness; fleeting nature: the lubricity of fame and fortune. lewdness; lustfulness: lasciviousness; salaciousness.
Are there any additives that can replace lubricity?
Additionally, many additives can offer added benefits such as cetane improver, and water separators or emulsifiers. In this study we will test multiple diesel fuel additives designed to replace lost lubricity. The primary component of this study is a side-by-side laboratory analysis of each additive’s ability to replace this vital lubricity.
Are there any studies on diesel lubricity additives?
The following are the preliminary results of a research study on diesel fuel Lubricity Additives. There is likely to be further commentary and explanation added at a future time.
Where are the lubricity and conductivity additives added?
Both lubricity additive and conductivity additive are commonly added to the ULSD products at the terminals. Both are sometimes added by all of the 4 injection point choices. The most common point for conductivity additive injection of USLD is option #2 (as it goes into the terminal storage tanks).
Where did the lubricity additive study take place?
This fuel was tested using the HFRR at the Southwest Research Laboratory. This fuel was determined to have a very high HFRR score of 636 microns, typical of an untreated ULSD fuel. It was determined that this batch of fuel would be utilized as the baseline fuel for testing all of the additives.
