“…Biodiesel viscosity can be considered as the main reason why the effects of biodiesel preheating should be studied. Therefore, experiments were conducted to assess the performance of the engine at different biodiesel inlet temperatures (30,40,50, 60 and 70°C). The results are presented for engine performance and pollutant emissions at different loads of up to 75% of the full load.…”

“…Tesfa et al [29] studied the influences of temperature and the biodiesel fraction on the physical properties, such as density and viscosity, of rapeseed, corn oil and waste oil biodiesels-diesel fuel blends and reported new correlations between the density and viscosity of different blends of biodiesel with diesel fuel. Karabektas et al [30] studied the Performance parameters and exhaust emissions of a diesel engine fuelled with diesel fuel and cottonseed oil methyl ester. Biodiesel was preheated to four different temperatures 30, 60, 90 and 120ºC.…”

The need for alternative fuel instead of conventional fossil fuels (diesel or gasoline) has recently increased for several reasons, including the expected shortage of petroleum fossil fuels and the production of pollution by transportation. Consequently, researchers are interested in finding new alternative fuels. At present, the number of studies on biodiesel as a compression ignition engine fuel has increased. Current studies are mainly concerned with studying the use of exhaust gas temperature to preheat biodiesel fuel before it enters the combustion chamber. A heat exchanger is designed to increase the temperature of the biodiesel fuel prior to the combustion process. The performance characteristics of diesel engines and the emission of pollutants resulting from this modification were investigated under different operating conditions, including different engine loads and speeds. The results showed clear improvements in engine performance, including improved output power, specific fuel consumption and pollutant emissions. The engine power and specific fuel consumption improvements as a result of preheating reached up to 1.3% and 8.27%, respectively. Pollutant emission also decreased obviously, with carbon monoxide and hydrocarbon emission decreases of 12.95% and 12.85%, respectively. However, the emission of nitrogen oxides increased by 4.39%.

“…They found that the BSFC of the four biodiesels was 10% higher than that of pure biodiesel because the tested biodiesel had a lower calorific value and 5% higher density than diesel. Another experimental study by Ruhul et al [193] using a single-cylinder diesel engine with variable load and speed conditions, fueled with Millettia pinnata (MP) biodiesel and Croton mega-locarpus (CM) biodiesel, also observed an increase in BSFC. The results of Mubarak et al [190] investigated the combustion and emission characteristics of Salvinia molesta oil biodiesel under different engine loads on a single-cylinder, four-stroke, air-cooled diesel engine.…”

Due to the increasing air pollution from diesel engines and the shortage of conventional fossil fuels, many experimental and numerical types of research have been carried out and published in the literature over the past few decades to find a new, sustainable, and alternative fuels. Biodiesel is an appropriate alternate solution for diesel engines because it is renewable, non-toxic, and eco-friendly. According to the European Academies Science Advisory Council, biodiesel evolution is broadly classified into four generations. This paper provides a comprehensive review of the production, properties, combustion, performance, and emission characteristics of diesel engines using different generations of biodiesel as an alternative fuel to replace fossil-based diesel and summarizes the primary feedstocks and properties of different generations of biodiesel compared with diesel. The general impression is that the use of different generations of biodiesel decreased 30% CO, 50% HC, and 70% smoke emissions compared with diesel. Engine performance is slightly decreased by an average of 3.13%, 89.56%, and 11.98% for higher density, viscosity, and cetane, respectively, while having a 7.96% lower heating value compared with diesel. A certain ratio of biodiesel as fuel instead of fossil diesel combined with advanced after-treatment technology is the main trend of future diesel engine development.

“…Since edible oils are too expensive to be utilized as a fuel in present days due to the enormous requirement for edible oils as food, the consideration of non-edible oils is very important for developing countries [12]. The most common nonedible feedstocks for the biodiesel industry have been regarded as Jatropha curcas [13], Cerbera odollam [14], Calophyllum inophyllum [15], Pongamia glabra [16], Sapindus mukorossi [17], Moringa oleifera [18], Croton megalocarpus [19], Azadirachta indica [20], etc. Apart from the above-mentioned non-edible oils, Styrax officinalis L. seed oil is a novel and important alternative non-edible raw material for the biodiesel production.…”

The development of renewable and sustainable candidates for petroleum-based fuels is needed to address the present issue of the increasing fuel crisis regarding transportation, environmental pollution, and consumption of the petroleum reserves. In addition, there is a need to explore new non-edible oils for biodiesel production due to problems such as fuel versus food as well as procurement and presence. Therefore the experimental research was carried out to synthesize biodiesel from Styrax officinalis L. oil. It has been firstly investigated and reported as a novel feedstock for the production of alternative fuel. The raw material was subjected to esterification at desired reaction parameters estimated by 9-runs (L9) orthogonal approach of Taguchi technique. Noteworthy, the oil content was found to be at 48.29 ± 3.81%. The maximum biodiesel yield of 89.23% was obtained under the following optimized conditions: catalyst concentration of 0.6 wt%, methanol to oil molar ratio of 6:1, reaction duration of 60 min and reaction temperature of 60°C. The detection of the substantial parameters was achieved using the Taguchi method and the significant parameters were obtained as follows: catalyst concentration, methanol to oil molar ratio, reaction duration, and reaction temperature with contribution factors of 78.07%, 20.32%, 0.42%, and 1.19%, respectively. Statistical analysis employing ANOVA exhibited that emerged outcomes are in good agreement with the predicted values. The fuel properties of the methyl esters from Styrax officinalis L. oil were within the ranges of the EN 14214 specifications. Therefore, the novel seeds can be a suitable feedstock for biodiesel production in the nearest future.
