“…The higher in-cylinder pressure of CI engine running with biodiesel blends may be attributed to the advanced combustion process initiated by the physical properties such as higher cetane number, viscosity, density and bulk modulus. The same phenomena were reported by Qi et al [3] and Muralidharan et al [29]. However, in recent publication Jaiichander et al [56] reported that the peak pressure is slightly lower for B20 when compared to that of diesel and they explained this might be due to improper mixing of B20 with air due to higher viscosity and lower calorific value for B20.…”

“…The increment of BSFC of the biodiesel compared to diesel is mainly due to the low heating value of the biodiesel as claimed by previous authors [20], [21], [23], [25] discovered by the author in this study. Some authors have also explained the increase in the BSFC in relation to the higher density and viscosity of the biodiesel [28], [29], [31]. In the lower heating value analysis, the heating value of the biodiesel was lower than the diesel by 11.1%.…”

“…The peak rate of heat release, peak cylinder pressure, indicated mean effective pressure (IMEP) and charge of temperature for this blend were found to be lower than that of diesel. The combustion characteristics of a single cylinder, four stroke which is running with waste cooking biodiesel were investigated by Muralidharan et al [29]. They found that the combustion characteristics of waste cooking oil methyl ester and its diesel blends closely followed those of standard diesel.…”

Biodiesel is one of the alternative fuels which is renewable and environmentally friendly and can be used in diesel engines with little or no modifications. In the present study, experimental investigations were carried out on the effects of biodiesel types, biodiesel fraction and physical properties on the combustion and performance characteristics of a compression ignition (CI) engine. The experimental work was conducted on a four-cylinder, four -stroke, direct injection (DI) and turbocharged diesel engine by using biodiesel of waste oil, rapeseed oil and corn oil and normal diesel. Based on the measured parameters, detailed analyses were carried out on cylinder pressure, heat release rate and brake specific fuel consumption (BSFC). It has been seen that the biodiesel types do not result in any significant differences in peak cylinder pressure and BSFC. The results also clearly indicate that the engine running with biodiesel have slightly higher in-cylinder pressure and heat release rate than the engine running with normal diesel. The BSFC for the engine running with neat biodiesel was higher than the engine running with normal diesel by up to 15%. It is also noticed that the physical properties of the biodiesel affects significantly the performance of the engine.

“…Fuels with high kinematic viscosity tend to form larger droplets during injection which can consequently lead to poor combustion. Therefore, the uneven combustion characteristics of the produced biodiesel fuel reduced the engine BP herein (Muralidharan et al, 2011 Figure 6 illustrates the variation of the BSFC values for the tested fuels at different engine speeds. It can be observed that the biodiesel-blended fuel (B5) resulted in higher BSFC values than the neat diesel fuel (B0).…”

Globally, more than 350 oil-bearing crops are known as potential biodiesel feedstocks. This study reports on production and characterization of Manketti (Ricinodendron rautonemii) methyl ester and its blends with diesel. The effect of Manketti biodiesel (B5) on engine and emissions performance was also investigated. The cloud, pour and cold filter plugging points of the produced biodiesel were measured at 1, 3 and 5 °C, respectively. However, the kinematic viscosity of the biodiesel generated was found to be 8.34 mm 2 /s which was higher than the limit described by ASTM D6751 and EN 14214. This can be attributed to the high kinematic viscosity of the parent oil (132.75 mm 2 /s). Nevertheless, blending with diesel improved this attribute. Moreover, it is observed that at all engine speeds, B5 produced lower brake power (1.18%) and higher brake specific fuel consumption (2.26%) compared to B0 (neat diesel). B5 increased the CO and HC emissions by 32.27% and 37.5%, respectively, compared to B0. However, B0 produced 5.26% higher NO emissions than B5.

Depletion of fossil fuel and massive emissions of hazardous greenhouse gases are prompting many researchers to focus on greener renewable fuel such as biodiesel, which has the potential to replace petrodiesel partially. This review covers various aspects related to biodiesel feedstock and its effects on biodiesel characteristics, biodiesel production methods, blending techniques, biodiesel properties, combustion, engine performance, and emission analysis, the effects of different additives on biodiesel characteristics, and some challenges associated with biodiesel. Moreover, different relevant empirical correlations of biodiesel properties and combustion parameters are presented. Despite alkali catalysis being the most adopted transesterification process, lipase catalysis and heterogeneous catalysis are potential processes for future biodiesel production from low‐cost feedstock. Biodiesel has higher viscosity, density, flash point, cetane number, and pour point while having low heating value in comparison with petrodiesel. Most studies conducted on diesel engine led to a reduction in brake power, brake thermal efficiency, carbon monoxide, sulfur dioxide, particulate matter, and unburned hydrocarbons, and increased brake specific fuel consumption and oxides of nitrogen are associated with biodiesel compared to petrodiesel. In brief, biodiesel is comparable to petrodiesel. However, before there is a large‐scale application of biodiesel in the automotive sector it has to overcome some challenges such as its compatibility with engine components, its instability, its effect on engine wear, deposit formation, and clogging of fuel filters and injectors. Increased focus should also be given to second‐generation biodiesel over first‐generation biodiesel because second‐generation biodiesel can offset production costs, reduce deforestation, and solve the food versus fuel problem. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.
