“…Furthermore, the presence of unsaturation and molecular oxygen in biodiesel blends produces higher in-cylinder temperature and, therefore, increased NOx emissions. Similar findings were reported by other researchers [15,58,70,84] who agreed that the increase in engine load will influence the NOx emissions to increase. Chauhan [58] observed the NOx emissions increased with the increased engine load, stating that the rise was caused by a greater combustion temperature.…”

Two main aspects of the transportation industry are pollution to the environment and depletion of fossil fuels. In the transportation industry, the pollution to the environment can be reduced with the use of cleaner fuel, such as gas-to-liquid fuel, to reduce the exhaust emissions from engines. However, the depletion of fossil fuels is still significant. Biodiesel is a non-toxic, renewable, and biodegradable fuel that is considered an alternative resource to conventional diesel fuel. Even though biodiesel shows advantages as a renewable source, there are still minor drawbacks while operating in diesel engines. Modern vehicle engines are designed to be powered by conventional diesel fuel or gasoline fuel. In this review, the performance, emissions, combustion, and endurance characteristics of different types of diesel engines with various conditions are assessed with biodiesel and blended fuel as well as the effect of biodiesel on the diesel engines. The results show that biodiesel and blended fuel had fewer emissions of CO, HC, and PM but higher NOx emissions than the diesel-fuelled engine. In the endurance test, biodiesel and blended fuel showed less wear and carbon deposits. A high concentration of wear debris was found inside the lubricating oil while the engine operated with biodiesel and blends. The performance, emissions, and combustion characteristics of biodiesel and its blends showed that it can be used in a diesel engine. However, further research on long-term endurance tests is required to obtain a better understanding of endurance characteristics about engine wear of the diesel engine using biodiesel and its blends.

“…The ratio of the engine's braking power to the fuel energy delivered to the engine is known as brake thermal efficiency (BTE) [70]. Many studies [44,46,47,[56][57][58][59]65] reported that the BTE of biodiesel is slightly lower than conventional diesel fuel.…”

“…The brake thermal efficiency also determines how well the engine converts the heat energy into actual mechanical energy. The BTE is influenced by engine design, type of fuel used and the engine application [56]. High engine load seems to increase BTE as can be seen in intermediate loads of 1000 r/min 50% engine load to 1500 r/min 75% engine load.…”

This study evaluated the performance of a diesel engine operated with waste plastic biodiesel fuel (WPPO) blends. Findings were that at all engine loads (from idling to full load) the emissions of carbon monoxide (CO), unburnt hydrocarbon (UHC) and carbon dioxide (CO2) were low compared to conventional diesel (PD), although the emissions of NOX were higher. The brake specific fuel consumption (BSFC) for the blends dropped while the brake thermal efficiency (BTE) increased with load for all blends until intermediate load when it decreased. WPPO blends had a higher viscosity compared to PD. CO emissions for blend 95/WPPO5 at all engine speed idling modes were 285 ppm, 298 ppm, 320ppm, and 388 ppm while PD emissions were 270 ppm, 295 ppm, 315 ppm and 365 ppm respectively. The values for UHC for blend 95/WPPO5 at all modes were 35 ppm, 28 ppm, 22 ppm, and 18 ppm compared to PD fuel with 20ppm, 25 ppm, 30 ppm, and 40ppm respectively. The NOX emissions for PD fuel at all modes were 175 ppm, 225 ppm, 300 ppm and 375 ppm compared to blend 95/WPPO5 at 195 ppm, 245 ppm, 335 ppm, and 397 ppm. The BSFC values for blend 95/WPPO5 at all modes were 0.48 kg/kW.h, 0.41 kg/kW.h, 0.35 kg/kW.h and 0.4 kg/kW.h compared to PD at 0.45 kg/kW.h, 0.39 kg/kW.h, 0.33 kg/kW.h and 035 kg/kW.h respectively.

“…From Figure , it is evident that at lower brake loads (upto 40%), the NO content in the exhaust was higher for diesel than for diesel–ethanol–ethyl acetate and diesel–ethanol–1-octanol emulsions, while it was found to be higher for the emulsions than for the diesel fuel at high BMEP (3.25–5.9 bar). There was an increase in combustion temperature due to the oxygen molecule present in ethanol, thereby resulting in increased NO x emissions . The results also depict that nitric oxide emission on diesel–ethanol–biodiesel emulsions was higher compared to diesel and other fuel blends.…”

A study was conducted to evaluate ethyl acetate, soy biodiesel, and 1-octanol as surfactants for stabilization of ethanol–diesel fuel blends. The evaluation was based on the temperature stability and engine performance of ethanol–diesel fuel blends stabilized by selected surfactants. Among the three selected surfactants, 1-octanol was most effective in stabilizing ethanol–diesel fuel blends. Out of 20 ethanol–diesel fuel blends prepared with 1-octanol as surfactant, only 3 blends showed distinct phase separation; the rest 17 remained stable in the entire temperature range of 0–45 °C. At the rated engine speed, eight ethanol–diesel fuel blends showed similar power-producing capability as that of diesel. The engine running on diesel developed a power of 3.71 kW, while the engine brake power with ethanol–diesel fuel blends was in the range of 3.67–3.74 kW at the rated load condition. The tested fuel blends resulted in slightly higher fuel consumption and increased emission of unburnt hydrocarbons as compared to the diesel fuel. The tested fuel blends had comparable thermal efficiency and acceptable UBHC and NO x emissions compared to diesel.
