“…This may be due to the presence of the oxygen molecule in biodiesel fuel, which leads to better combustion compared to NDF. Similar results are obtained in the relevant literature (Khiari et al 2015;Uyumaz et al 2020;Sathyamurthy et al 2021;Kondaiah et al 2021). For example, Khiari et al (2015) examined the effects of NDF and neat Pistacia Lentiscus biodiesel fuel on cylinder pressure values, cylinder temperature values, and HRR in a single-cylinder diesel engine.…”

In the current study; firstly, biodiesel was produced by the transesterification method from refined corn oil. After the biodiesel production, effects of the using neat biodiesel (B100) and different biodiesel/diesel fuel blends (BDFBs) on combustion, engine performance, and exhaust emissions were experimentally investigated in a diesel engine. Also, using the heat release rate (HRR) curves, an empirical correlation was developed for estimating the CD for the test engine. Tests were performed for neat diesel fuel (NDF), B100, and five different BDFBs such as (5, 10, 15, 20, 50; v/v) % under full load and at nine engine speeds. At the end of this study, it has been determined that using biodiesel slightly reduces the brake effective power and effective efficiency, but it increases significantly the specific fuel consumption (BSFC). Using biodiesel increases the BSFC by an average of 3-20%. On the other hand, using biodiesel evidently reduces CO and soot emissions, and increases HC emissions and CO2. The selected BDFBs and B100 increase the cylinder pressures in all selected operating conditions. The use of biodiesel has not shown substantial changes in HRR values. Combustion duration values increase up to (10-15) % biodiesel ratios, after these ratios, they start to decrease.

“…The increase in combustion temperature means that more fuel is discharged in the form of CO 2 and H 2 O, rather than partially burned HC. Compared with the results of other authors, we observed a similar emission trend, that is, the HC emissions of castor biodiesel blend fuel are lower than diesel, which further confirms the fact that the HC emissions of biodiesel fuel are lower [24,35].…”

“…The use of nonedible vegetable oil biodiesel to solve food price problems is good [23]. In addition, compared to diesel fuel, castor biodiesel blends have lower emissions of harmful gases such as carbon monoxide (CO) and hydrocarbons (HC) [24]. Arunkumar et al [25] believe that castor biodiesel, as a good alternative to diesel, can greatly reduce greenhouse gas emissions.…”

Faced with the depletion of fossil fuels and increasingly serious environmental pollution, finding an environmentally friendly renewable alternative fuel has become one of the current research focuses. In order to find new alternative fuels, reduce dependence on fossil fuels, improve air quality, and promote sustainable development goals, castor biodiesel was produced through transesterification, and mixed with diesel in a certain proportion. The engine performance and emissions were compared and analyzed under fixed load and different speeds of agricultural diesel engines. Biofuel, as a fuel containing oxygen, promotes complete combustion to a certain extent. As the proportion of castor biodiesel in the mixed fuel increases, the emissions of pollutants such as CO, HC, and smoke show a decreasing trend. The lowest CO, HC, and smoke emissions were observed in the B80 blend at 1800 rpm, at 0.3%, 23 ppm, and 3%, respectively. On the contrary, the CO2 and NOx emissions of the B80 blend are higher than those of 2.7 diesel, reaching 2.5% and 332 ppm respectively at 1800 rpm. The lower calorific value and higher viscosity of biodiesel result in a decrease in BTE and an increase in the BSFC of the blends. Higher combustion temperatures at high speeds promote oxidation reactions, resulting in reduced HC, CO, and smoke emissions, but increased CO2 and NOx emissions. At high speeds, fuel consumption increases, BSFC increases, and BTE decreases. Overall, castor biodiesel has similar physical and chemical properties to diesel and can be mixed with diesel in a certain proportion for use in CI engines, making it an excellent alternative fuel.

“…In addition, high-speed combustion is often accompanied by higher temperatures and pressures, which help achieve better mixing and combustion in the combustion chamber. Compared with the research results of other researchers, we found the same trend, that is, the HC emissions of castor biodiesel blends are lower than that of diesel fuel [19,20], which further confirms that biodiesel fuel has lower HC emissions.…”

Fossil fuel is a non-renewable fuel, and with the development of modern industry and agriculture, the storage capacity of fossil fuels is constantly decreasing. In this study, a systematic study and analysis were conducted on the combustion characteristics, engine performance, and exhaust emission characteristics of castor biodiesel–diesel blends and pure diesel fuel in different proportions at different speeds of a single-cylinder four-stroke diesel engine under constant load. The castor biodiesel required for the experiment is generated through an ester exchange reaction and mixed with diesel in proportion to produce biodiesel–diesel blends. The experimental results show that as an oxygenated fuel with a higher cetane number, the CO, HC, and smoke emissions of diesel and B80 blend fuel at 1800 rpm were reduced by 16.9%, 31.6%, and 68%, respectively. On the contrary, the NOx and CO2 emissions increased by 17.3% and 34.6% compared to diesel at 1800 rpm. In addition, due to its high viscosity and low calorific value, the brake thermal efficiency and brake-specific fuel consumption of the biodiesel–diesel blends are slightly lower than those of diesel, but the biodiesel–diesel blends exhibit lower exhaust gas temperatures. Comparing B80 and diesel fuel at 1800 rpm, the BSFC of diesel at 1800 rpm is 3.12 kg/W·h, whereas for B80 blended fuel, it increases to 4.2 kg/W·h, and BTE decreases from 25.39% to 21.33%. On the contrary, B60 blended fuel exhibits a lower exhaust emission temperature, displaying 452 °C at 1800 rpm. Based on the experimental results, it can be concluded that castor biodiesel is a very promising clean alternative fuel with low waste emissions and good engine performance.
