An investigation into the tribological performance of Diesel and Diesel-GTBE blends.

摘要

Glycerol Tertiary Butyl Ether (GTBE) has been recognized as an additive for both bio- and fossil diesel. When blended invarying concentrations GTBE reduces PM emissions significantly in diesel engines. Addition of GTBE affects lubricity ofdiesel and therefore caters interest to investigate the tribological performance of diesel-GTBE blends prior to engine testing.The aim of present research is to investigate the tribo-performance of diesel and diesel-GTBE blends in laboratoryconditions. An in-house synthesized GTBE is blended with three commercial diesel samples and the performance in terms offriction and wear is investigated. Experiments are performed on a four ball tester using varying concentrations of GTBE incommercial diesel samples procured from Indian market. The SEM investigations of the used test specimens were carriedout. Experimental results indicating the effect of GTBE concentration in diesel on the wear and frictional force has beenanalyzed and reported.
