Investigation of Performance and Emission Characteristics of CI Engine Using Diesel and Waste Cooking Oil Blends

Reusing waste cooking oil (WCO) as fuel in compression ignition (CI) engine offers a sustainable solution for energy scarcity and environmental protection. WCO n-pentanol ternary blends deliver are attractive prospects utilization bio-components recycled components to moderately substitute diesel fuel. The current study intends investigate the performance emission characteristics of single cylinder CI engine, having constant load at uniform speed 1300 rpm, using diesel-waste blends. Blends chosen analogized with reference their contents were following: (1) D95-WCO5 (95%vol. diesel, WCO5%vol. oil, (2) D65-WCO20-Pe15 (65%vol. 20%vol. 15%vol. n-pentanol) (3) D60-WCO20-Pe20 (60%vol. n-pentanol). experimental results revealed that DF95-WCO5 blend BSFC improved by 0.32%. However, addition blend; DF65-WCO20-Pe15 DF60-WCO20-Pe20 resulted improvements 0.49% 0.68% respectively. BTE increased 38.7%, while increase was 39.2% 39.6% DF60-WCO20-Pe20, which less, compared lowermost level CO discharge achieved when fueled due highest saturation. CO2, cases increased, under same operating conditions. binary decreased CO2 because incomplete combustion During work it could be observed produced higher Particulate material (PM-1, PM-2.5, PM-7 PM-10) emissions, DF100. Moreover, ratio 15 20%, further reduced. This indicated direct exertion engines must promoted, is an impressive choice recapture.
