摘　　要：In this extensive investigation,the impact of borax decahydrate as a fuel additive in a diesel single-cylinder engine was rigorously examined.Borax decahydrate was introduced at concentrations of 5,15,25 and 35 g in 500 ml of biodiesel,forming five unique fuel mixtures with conventional diesel:90%diesel+10%spirulina biodiesel(SB10),SB10+1 g borax decahydrate(SB10B1),SB10+3 g borax decahydrate(SB10B3),SB10+5 g borax decahydrate(SB10B5)and SB10+7 g borax decahydrate(SB10B7).The investigation encompassed four diverse loading conditions and yielded insightful findings.Notably,at full load,SB10B3 exhibited a higher cylinder peak pressure than diesel,reaching 69.25 bar.Heat release rate profiles demonstrated superior efficiency for SB10 at 50%load,with a cumulative heat release rate of 950 J/°CA,which is lower than the 1050 J/°CA of diesel.Knock intensity(KI)evaluations revealed that,although SB10 and SB10B1 exhibited higher KI than diesel at full load due to elevated peak pressure,SB10B7 showed no knocking across all loads,indicative of reduced in-cylinder combustion.This meticulous numerical analysis emphasizes the potential of borax decahydrate as a catalyst and enhancer,providing valuable insights into the combustion dynamics of these alternative fuel blends and their viability for sustainable and efficient engine performance.In summary,out of all the blends,SB10B3 could be a potential diesel fuel replacement fuel for compression-ignition engines.
