“…However, KSO also contains up to 15% cyclopropenoid fatty acids [ 6 ], which are toxic, rendering KSO unsuitable for consumption as an edible oil [ [7] , [8] , [9] , [10] ]. Various non-edible applications for KSO have been explored, including biodiesel [ [11] , [12] , [13] , [14] , [15] ], nanofluid [ 16 , 17 ], bio-lubricant [ 18 ], and antibacterial [ 19 ].…”

“…Furthermore, using the B20 fuel blend in engines does not necessitate any significant engine modifications. 20 Equivalent performance was acquired and a reduction in emission was obtained with biodiesel instead of diesel. 21 A researcher uses a variety of methods to reduce NO x emissions, including biofuel mixes, engine modifications, exhaust gas reuse techniques, and fuel compositions.…”

Recently nano additives have proven their significance in biodiesels to overcome the challenges of fossil fuels in CI engines. The current study examines the performance and exhaust emission characteristics of a CI engine on waste cooking oil biodiesel (WCME) blends with Titanium oxide (TiO2) nano additives. TiO2 of 50 and 100 ppm were added in WCME blends with the help of magnetic stirring, followed by ultrasonication. Test fuel with 100 ppm of TiO2 and WCME30 (30% WCME and 70% neat Diesel) showed a 4.04% improvement in brake thermal efficiency and a 3.3% decrement in BSEC. Moreover, lowered NOx, HC, and CO exhaust emissions by 1.7%, 14%, and 17.46% respectively than neat Diesel. So WCME30 with 100 ppm concentration of TiO2 can be utilized as a potential fuel for a single cylinder four-stroke compression ignition engine with the compression ratio of 18:1.

“…CI engines running on biodiesel emit more NOx due to the improved burning of oxygenated biodiesel. Biodiesel caused advanced injection time, which enhances NOx emissions (Bakthavathsalam et al 2019). The biodiesel-powered engine's fuel injection timing and combustion behaviour are impacted by its increased viscosity and bulk modulus are identi ed as a primary contributor to NOx emissions.…”

Pollution from diesel engines affects negatively the environment. As a result, there is a worldwide concern about reducing the pollutants emitted by diesel engines. In comparison to diesel fuel, biodiesel combustion produces reduced carbon monoxide (CO2) and unburned hydrocarbon (UHC) emissions, but higher nitrogen oxides (NOx) emissions. The current study is to investigate the thermal and chemical effect of exhaust gas recirculation (EGR) on features of a diesel engine for environmental sustainability. The punnai oil was produced from kernels of punnai seeds and transesterified in two phases using alcohol with the existence of a catalyst. The higher viscosity of punnai oil biodiesel is diluted by mixing it with diesel fuel. Our previous investigation indicated that neat punnai oil biodiesel is a potential fuel; however, the findings showed that the addition of diesel is necessary to obtain acceptable engine performance. In this study, punnai oil biodiesel was mixed at a rate of 20% with diesel (B20) and run in a diesel engine with varied EGR rates under five different engine loads. This combined impact enhanced the maximum heat release rate (HRR) and maximum combustion pressure, according to the findings. The premixed burning fractions were commonly higher at all engine loads, whereas the diffusion combustion fractions were lower. When the centre of the HRR changed toward the top dead centre (TDC), combustion durations remained rather constant. The experimental results revealed B20 blend at 10% EGR flow rate produced 6.57% lower BTE, 37.04% higher BSEC, 2.47% higher EGT, 5.13% lower CO, 31.11% higher CO2, 3.13% higher UHC, 8.36% lower NOx and 4% higher smoke opacity when compared with diesel in a standard diesel engine.
