摘要: Abstract In this study, waste cooking oil from restaurants was used to produce a renewable and sustainable biodiesel through transesterification process. The Treated Waste Cooking Oil (TWCO) fuel produced has shown very promising chemical physical properties; most notably; cetane number (∼49) sulphur content (8 mg/kg). combustion of conventional diesel (TWCO)–diesel blend (50/50 by volume; as TD50) examined at different engine conditions. TD50 resulted in considerable reduction the smoke opacity unburnt hydrocarbons associated with an increase CO 2 NO x emissions due unintentional advance injection timing, caused higher bulk modulus fuel. Results indicated brake specific consumption simultaneous thermal efficiency compared diesel. lower case assists reductions exploiting EGR tolerance Thus, more encouraging -smoke tradeoff may be selected reduce both smoke. effect noticeable than
