This paper aims to investigate the emission characteristics of biodiesel prepared from the waste cooking oil. The characterization of the performance of the blended fuel in diesel engines results in an improvement and a reduction in hydrocarbon and carbon monoxide emissions. Various amounts of fuel were mixed with leftover cooking oil to create the final product. In order to explore the performance function, combustion range, and emission properties of diesel engines, the setup described here was developed. The combustion properties, including exhaust gas emissions of NOx, CO, CO2, HC, smoke, and O2, have been examined under various load scenarios.

In this research, the performance and emissions of a Diesel engine were investigated under three fuel configurations: Diesel, a B-20 biodiesel blend with an HfC-coated piston, and a B-20 blend with an uncoated piston. The results illustrated Diesel's superior performance, achieving a Brake Specific Fuel Consumption (BSFC) of 0.2 kg/kWh at 7 kW brake power, coupled with the lowest emissions: CO at 30 ppm, HC at 14 ppm, NOx at 105 ppm, and smoke at 55 ppm. The HfC-coated piston running on B-20 biodiesel blend showed promising results, registering a BSFC of 0.25 kg/kWh and emissions of CO at 34 ppm, HC at 18 ppm, NOx at 110 ppm, and smoke at 60 ppm at the same brake power. In contrast, the B-20 blend in the uncoated piston recorded a BSFC of 0.28 kg/kWh with emissions of CO at 37 ppm, HC at 20 ppm, NOx at 114 ppm, and smoke at 65 ppm. The study underscores Diesel's inherent efficiency but also highlights the potential of engine modifications, like the HfC coating, to substantially optimize the combustion efficiency of biodiesel blends, bridging the performance and emissions gap with conventional Diesel.

The need for sustainable alternative fuels is becoming increasingly urgent because to the rapidly expanding demand for automobiles and the growing concerns over the fossil fuel diminution. This research looks into how biodiesel, specifically blends made from rapeseed oil (RSO), can fill this new need. RSO is created through transesterification, which yields a biodiesel with characteristics that meet ASTM requirements. In a 5.1 KW, single-cylinder, turbocharged diesel engine (Turbo-DE), the performance, emissions, and combustion (P-E-C) characteristics of several RSO-diesel blends (B20, B40, B60, and B80) are examined and contrasted with those of pure diesel. According to the findings, brake thermal efficiency slightly decreases as biodiesel proportion in the blend rises. The environmental advantages of these blends are offset by a sizable decrease in smoke, Carbon Monoxide (CO), and Hydrocarbon (HC) emissions. On the other hand, greater biodiesel ratios result in higher emissions of Nitrogen Oxides (NOx) and Carbon Dioxide (CO2). The thermal efficiencies of the brakes for diesel, B20, B40, B60, and B80 blends were found to be 29.3%, 28.6%, 27.9%, 27.2%, and 26.9%, respectively, in the detailed results. While smoke emissions decreased from 55% (diesel) to 40% (B80), NOx emissions ranged from 1556 ppm (diesel) to 1718 ppm (B80). The B20 blend's combustion characteristics closely resemble those of diesel, with maximum cylinder pressures and Ignition delay of 78 bar, 73 bar, 20%, and 18%, respectively, for diesel and B20. These results offer a good starting point for additional investigation into sustainable alternative fuels by shedding light on the prospective performance and ecological impact of biodiesel-diesel mixes.
