“…Among considered injectors, the 8-hole type exhibits lower ignition delay compared to others. Increased temperature resulting from homogeneous mixtures could be the reason for the observed trends [10]. Figure 18a,b depicts the variation of ignition delay with selected biodiesels for various combustion chamber shapes for 80 and 100% loads, respectively.…”

“…Addition of CNT nanoparticles in the fuel blends reduced the emission levels. Dharmarajaa et al [10] studied the emission characteristics of a 4S-single-cylinder DI engine at the rated engine speed of 1500 rpm using 16-20% of rice husk crude oil. Increased thermal efficiency and ignition delay (ID) at higher loads were observed for the 20% blend due to a higher cetane number for the viscous fueled engines.…”

Environmentally friendly, renewable, and green fuels have many benefits over fossil fuels, particularly regarding energy efficiency, in addition to addressing environmental and socioeconomic problems. As a result, green fuels can be used in transportation and power generating applications. Furthermore, being green can ably address the emission-related issues of global warming. In view of the advantages of renewable fuels, two B20 fuel blends obtained from methyl esters of cashew nutshell (CHNOB), jackfruit seed (JACKFSNOB), and jamun seed oils (JAMSOB) were selected to evaluate the performance of a common rail direct injection (CRDI) engine. Compatibility of the nozzle geometry (NG) and combustion chamber shape (CCS) were optimized for increased engine performance. The optimized CCS matched with an increased number of injector nozzle holes in NG showed reasonably improved brake thermal efficiency (BTE), reduced emissions of smoke, HC, and CO, respectively, while NOx increased. Further combustion parameters, such as ignition delay (ID) and combustion duration (CD) reduced, while peak pressure (PP) and heat release rates (HRR) increased at the optimized injection parameters. The CRDI engine powered with JAMSOB B20 showed an increase in BTE of 4–5%, while a significant reduction in HC and CO emissions was obtained compared to JACKFSNOB B20 and CHNOB B20, with increased NOx.

Biomass is an important renewable energy resource which primarily contributes to heating and cooling end use sectors. It is also a promising alternative source of biofuels to replace the depleting supply of fossil fuels. Surprisingly, few writers have been able to draw on the feedstock significance for oil palm empty fruit bunch (EFB) as the biomass resource for biofuels compared to the other types of biomass waste. Therefore, this paper presents a comprehensive review of EFB as a biomass resource presented in four major parts. First, the introduction covers the demand for bio-oil and describes the different kinds of feedstock, the relevance and potential of EFB biomass. Second, the characteristics of biomass are explained before it is upgraded as biofuel, drawing similarities and contrasts between EFB and other sources of biomass. Pyrolysis processes and reactors used for EFB conversion are described, and the factors affecting the bio-oil yield and quality are discussed. Major reactor parameters are summarized and reactor optimization is discussed. Third, comparison on the properties of the bio-oil vs. petroleum in transportation, power generation, and heating are compared followed by prioritizing the bio-oil properties from the most to least critical, revealing the most promising methods for upgrading. Fourth, the environmental impact, including CO2 emission, of the use of EFB as a promising renewable energy resource and a cleaner alternative fuel is recommended. This paper has comprehensively reviewed the conversion of oil palm empty fruit bunches into biofuels, including the similarities and differences between biomasses, the best reactors, its comparison with fossil fuels, and bio-oil upgrading methods. The upgrading mapping matrix is created to present the best upgrading strategies for the optimum quality of biofuels. This paper serves as a one-stop center for EFB conversion into biofuels.

“…Jeyaprakash et al (2019) investigated rice bran biodiesel in a four-stroke, single-cylinder, directinjection engine which runs at 1500 rpm is made in which the biodiesel blend of 20%(B20) has greater values when compared with other blending ratio. Their results show that the rice husk contains about 16-20% of crude rice bran oil, and it has high in-cylinder pressure of about 72.1 bar and heat release rate of about 70.826 J/CA [15].…”

Our research work mainly focusses on the examination of properties, both physical and chemical, of biodiesel blends among neat diesel at different volumetric proportions. Properties like viscosity; calorific value (CV); pour point (PP); cetane number; could point (CP); flash point and fire point are measured for each blending ratios, and it is examined against the relevant standards (USA ASTM D 6751; Europe EN:14214 as well as India IS:15607). Plot between the properties and different blending ratios is drawn, and regression equations (R2) are formulated from which biodiesel properties are predicted and compared by mineral diesel. From this investigation, the optimal blending ratio is projected considering the different properties of biodiesel.
