Lubricity additives for motor fuels

Abstract

The paper describes the origin of insufficient lubricity properties of motor fuels, the essence of the problem and laboratory test methods applied to determine fuel lubricity. Ways applied by fuel industry to enhance lubricity are presented. There was also carried out a patent analysis concerning lubricity additives and fuel compositions. The anti-wear behaviour of lubricity enhancers, their types and possible undesirable effects were described.
