Improvement of exhaust emissions in a diesel engine with the addition of an oxygenated additive to diesel-biodiesel blends

Emissions control in internal combustion engines is the big challenge faced by engine manufacturers. Modern exploit various systems to reduce exhaust emissions. However, existing emission will fall short of meeting stringent future regulations. This study attempts emissions a diesel fuelled with diesel-biodiesel blends utilising ethyl acetate as renewable oxygenated fuel additive. In this context, initially, mixed biodiesel-diesel 5% and 10% volume obtain test fuels. Then, their properties are measured applying methods proposed standards. Subsequently, experiments conducted on single-cylinder four-stroke operated distinct conditions. The findings indicate that inclusion improves quality markedly decreases A substantial reduction achieved NOX, soot, CO up 50%, 70%, 71%, respectively, slight increase consumption case adding acetate. More importantly, addition enhances NOX-smoke trade-off NOX-BSFC characteristic without loss thermal efficiency. From research, it can be inferred potentially blends.
