“…Te emission performance of nanofuels and hybrid nanofuels is as follows: In full-load conditions, 20%, 26%, 24%, and 29% less CO emissions were obtained by BWTPO, BWTPO + MWCNT, BWTPO + TiO 2 , and BWTPO + MWCNT and TiO 2 fuels, respectively, when compared with diesel fuel. BWTPO, BWTPO + MWCNT, BWTPO + TiO 2 , and BWTPO + MWCNT and TiO 2 fuels, respectively, have 42%, 45%, 48%, and 50% less unburned hydrocarbon emissions than diesel fuel in full-load conditions [30]. BWTPO, BWTPO + MWCNT, BWTPO + TiO 2 , and BWTPO + MWCNT and TiO 2 fuels, respectively, have 33%, 20%, 17%, and 13% less carbon dioxide emissions than diesel fuel in full-load conditions [31].…”
