“…The fluctuation in CO emission according to load for diesel, CFAD, and its blends is revealed in Figure 12. The existence of CO elements in engine exhaust specifies that not all of the fuel's chemical energy is being used to generate engine power 34 .

This study examined the potential of using coconut fatty acid distillate (CFAD), a by‐product of the processing of edible oils, as a diesel engine fuel. The major novelty of this study is to assess the CFAD as a viable feedstock of biodiesel to address global energy demands. CFAD has not been specifically researched as a feedstock for producing biodiesel or as a fuel for diesel engines, despite the fact that numerous studies on the production and performance of biodiesel have already been conducted. Fourier transform infrared (FTIR) spectroscopy, gas chromatography (GC), and FTIR were used to analyze the fuel. According to the results of the GC test, CFAD oil contains 91.53% saturated fatty acids, compared with only 8.47% unsaturated fatty acids. High saturation values can be seen in myristic acid (16.92%) and lactic acid (45.33%). Longer hydrocarbon chain lengths indicate higher energy density and boiling point, which also indicate lesser volatility. At a frequency of 1708.54 cm−1, C─H stretching vibrations have been identified through FTIR investigation. The vibrations of C─C stretching at 1465.47 cm−1 indicate the presence of alkenes/fingerprint phase. The blends used for this investigation include 90% diesel with 10% CFAD (CFAD10), 80% diesel with 20% CFAD (CFAD20), 70% diesel with 30% CFAD (CFAD30), and 100% CFAD. The CFAD 10%, 20%, and 30% blends as well as the CFAD100 had brake thermal efficiency values of 27.24%, 26.23%, 24.88%, and 21.52%, correspondingly, at full load. The average increment in brake‐specific energy consumption for CFAD10, CFAD20, CFAD30, and CFAD100 over diesel fuel was 8.23%, 10.88%, 13.77%, and 25.90%, respectively. The behavior of CFAD exhibits reduced cylinder pressure because of the large content of moderate saturated fatty acids in this substance. The net heat release rate (NHRR) and cylinder pressure have a similar relationship in that the NHRR increases with increasing diesel volume. In comparison to diesel, the CO emissions from the CFAD20, CFAD30, and CFAD100 blends increased by 10.79%, 16.66%, and 35.89% at maximum load, respectively. It has been reported that NOx is reduced more significantly the more CFAD is present in the mixture. The blend CFAD10 had the least amount of smoke. The high viscosity of the CFAD and its blends influences the fuel droplets range and the development of spray in the cylinder, which results in delayed combustion and higher unburned hydrocarbon emissions.

“…The existence of CO elements in engine exhaust specifies that not all of the fuel's chemical energy is being used to generate engine power. 34 Due to incomplete combustion, carbon monoxide and HC emissions are produced. In every test, the CFAD10 mix had the lowest CO emission of any fuel, and it was 4.8% less than diesel.…”

The increase in the use of plastic products and disposal of the same pose a threat to the world community due to its poor biodegradability. Chemically treating the waste plastic to extract oil and using as the fuel in the form of blends will safeguard the environment. It was observed that viscosity and lubricity of such oils were lower than standard diesel. High Ricinoleic fatty acid ester is added to improve the lubricity of novel pyrolytic blend. Lower blends were prepared for the investigation. Cator ester was added to Pyro‐Diesel along with graphene quantum dot (GQD). The fuel blend is prepared with concentration of 30 ppm GQD nano‐particles. The investigation was made on using CME and PD20 blend. The blend was prepared using Castor oil methyl ester, Pyrolytic oil and nano particle Graphene Quantum Dot (GQD). GQD has extraordinary ecological characteristics such as biocompatibility, large surface area excellent solubility. This combination is a novel work which resulted in reduced emissions. The results reveal that oxides of nitrogen and smoke were increased for all the ternary blends but combustion characteristics improved. The performance of PCD10 (10% CME + 20% Pyro + 70% Diesel) was higher than that of Pyro‐Diesel blend. Hence, ternary blend may be chosen as fuel.
