Efficacy of a bio-additive on the exhaust emissions of petrodiesel

The performance of a potential oxygenate bio-additive for petrodiesel is reported in this study. The evaluation of the 2.5 (wt%) blend of the bio-additive glycerol tertiary butyl ether (GTBE), when tested on a midsize diesel passenger car, shows reduction in total hydrocarbons (THC) of 52.87 %, carbon monoxides (CO) of 53.33 %, carbon dioxide (CO2) of 6.51 %, and fuel economy benefits of 7.13 %. However, there is an increase in NO X values. Structural analysis is completely supported by detailed NMR studies including chemical shifts of 1H- and 13C-type distributions and 1H–13C connectivity.
