润滑性改进剂

Lubricity improvers are used in diesel and other middle-distillate fuels where the untreated fuel provides insufficient lubrication. Selection focuses on measured lubricity, required finished-fuel performance and compatibility with the complete additive package.

应用与功能

Fuel lubricity is relevant to wear in fuel-injection equipment. Lubricity additives are evaluated where the base fuel needs treatment to achieve a defined lubricity target.

Formulation chemistry affects selection and handling. Ester-based formulations are among the documented options. Individual formulation characteristics should be reviewed against the actual fuel.

选型信息

  • Base-fuel composition and untreated lubricity
  • Target specification and agreed test method
  • Other fuel additives and potential process carryover
  • Storage conditions, blending location and dosing equipment

评估该回复

Compare treated and untreated samples using a suitable bench test, such as the high-frequency reciprocating rig method. Establish the response in the intended blend.

Review finished-fuel compatibility and handling alongside the lubricity result. Define a blending and quality-control plan for routine use.
