Abstract

    Diesel engine discharge characteristics are primarily influenced by fuel qualities, combustion chamber type, and injection settings. This study used combinations of biodiesel, waste cooking oil, and diesel fuel to do a parametric investigation on a diesel engine (DF80-WCOB20, DF70-WCOB30, DF60-WCOB40, and DF50-WCOB50). Using a complete factorial design L75 orthogonal array (O.A.), the experimental and parametric investigations were carried out. According to the experimental findings, DF80-WCOB20, DF70-WCOB30, DF60-WCOB40, and DF50-WCOB50 increase specific energy consumption while reducing engine efficiency, carbon monoxide emissions, and hydrocarbon discharges. At all engine loads, DF80-WCOB20′s brake thermal efficiency (BTE) was higher than that of DF70-WCOB30, DF60-WCOB40, and DF50-WCOB50 for respective compression ratios of 16.5, 17.5, and 18.5. Additionally, the BSFC for C.R. increases (16.5, 17.5, and 18.5) at all engine loads when waste cooking oil biodiesel is mixed with diesel fuel compared to diesel fuel. The findings indicate that while adding biodiesel made from used cooking oil to diesel fuel greatly reduces carbon monoxide and hydrocarbon emissions, it also results in higher nitrogen oxide emissions than diesel fuel.
