摘要: Abstract The exhaust gas emissions from a compression ignition (CI) engines are mostly depend on the nature of fuel mixture, combustion chamber, and injection parameters. Higher temperature, which leads to oxides nitrogen (NOX) emission. In present study, an engine single-cylinder, direct cooling was operated at 1500 rpm speed with variable loads. Numerical simulation is performed using blends diesel, spirulina microalgae biodiesel (BSP20, BSP40, BSP100), diesel-spirulina – ethanol (DSP80E20). this variation in timings (15.5° b TDC 27.5° TDC), nozzle diameters (0.15 mm − 0.4 mm), swirl ratios (0.5–3.0) investigated for emission characteristics (NOX, particulate matter, smoke summary emission). Results indicated that by increasing diameter (ND), timing (IT) ratio (SWR) NOX increased noticeably. Additionally, ND, IT SWR higher matter diesel DSP80E20 but lower BSP20 BSP40 blends. reduction DSP80E20, as compared fuel. results showed 0.25 mm (nozzle diameter) microalgae, ethanol-blended better response. Smoke reduced due oxygen percentage within A significant decrease also observed.
