Fretting wear performance of diesel fuel lubricity additives Available to Purchase

The paper describes the evaluation of the fretting wear performance of diesel fuel additives as opposed to the sliding wear performance which is normally evaluated, and in fact forms part of the diesel fuel specification. Variations in load, frequency and running time were employed to ensure that all conditions which were like ly to be encountered were properly evaluated. Clear differences were observed between fretting wear performance and sliding wear performance, which is significant in view of the fact that fretting wear is often a factor for certain components of the fuel injection equipment. Further work on establishing the repeatability, reproducibility and participating in a “round robin” series of trials is indicated.
