“…This is the possible next target within the framework of ecology and sustainability of transport. Concentrations of 15 and 30% are commonly tested and reported in publications dealing with similar topics (Pradelle et al 2017;Devarajan et al 2022;Reang et al 2022). Furthermore, B15 and B30 is currently used in countries such as Indonesia or Brazil.…”

“…According to Abed et al (2018) and Siva et al (2019), this phenomenon occurs because the calorific value of diesel fuel is higher than biodiesel. Reang et al (2022) tested diesel-biodiesel-rice wine alcohol and state that at full load D80B10RW10, D70B20RW10, and D60B30RW10 gives 1.46%, 2.86%, and 3.91% lower brake thermal efficiency (BTHE) than diesel used in single cylinder compression ignition engine. Datta and Mandal (2017) found that the BTHE and fuel efficiency of a compression ignition engine increases while using alcohol (methanol and ethanol) with biodiesel.…”

Due to the ever-increasing consumption of fossil fuels, their impact on the environment, and the volatility of the market, it is advisable to use biofuels that can be produced locally from renewable sources, which supports the local economy, agriculture, and related processing industries. This article deals with how to improve the flow properties and pour point of biofuels for diesel engines. For the experiment, biodiesels in the form of rapeseed methyl ester (RME) and methyl ester made from waste animal fats and tallow (WAFME) were used. The pour point, viscosity, and density of WAFME were improved by mixing with RME and/or by adding bio-alcohols (alcohols produced from biomass, e.g., lignocellulosic). All used biofuels were classified as 2nd generation biofuels. The flow properties of the mixtures were monitored and subsequently modelled at temperatures from -10 to 60 °C. The addition of bio-alcohol had a statistically significant effect on the decrease in the viscosity and pour point of ternary blends (p < 0.05). Mathematical models of the dependence of kinematic viscosity on the temperature of mixtures (power law, exponential, Arrhenius, and Vogel) were created.

“…Diesel fuel has a crucial problem related to exhaust, vibration, and acoustic emissions [7][8][9][10][11]. Biodiesel is considered an eco-friendly, bio-degradable, energy efficient, renewable, scientifically feasible, and non-toxic fuel alternative [12][13][14]. Besides, it is considered one of the safest fuels, because it has a high flash point amongst all conventional fuels [15], and can operate diesel engines with little or no adjustments [16].…”

Modeling and Optimization of a Compression Ignition Engine Fueled with Biodiesel Blends for Performance Improvement

Biodiesel is considered to be a promising alternative option to diesel fuel. The main contribution of the current work is to improve compression ignition engine performance, fueled by several biodiesel blends. Three metrics were used to evaluate the output performance of the compression ignition engine, as follows: brake torque (BT), brake specific fuel consumption (BSFC), and brake thermal efficiency (BTE), by varying two input parameters (engine speed and fuel type). The engine speeds were in the 1200–2400 rpm range. Three biodiesel blends, containing 20 vol.% of vegetable oil and 80 vol.% of pure diesel fuel, were prepared and tested. In all the experiments, pure diesel fuel was employed as a reference for all biodiesel blends. The experimental results revealed the following findings: although all types of biodiesel blends have low calorific value and slightly high viscosity, as compared to pure diesel fuel, there was an improvement in both BT and brake power (BP) outputs. An increase in BSFC by 7.4%, 4.9%, and 2.5% was obtained for palm, sunflower, and corn biodiesel blends, respectively, as compared to that of pure diesel. The BTE of the palm oil biodiesel blend was the lowest among other biodiesel blends. The suggested work strategy includes two stages (modeling and parameter optimization). In the first stage, a robust fuzzy model is created, depending on the experimental results, to simulate the output performance of the compression ignition engine. The particle swarm optimization (PSO) algorithm is used in the second stage to determine the optimal operating parameters. To confirm the distinction of the proposed strategy, the obtained outcomes were compared to those attained by response surface methodology (RSM). The coefficient of determination (R2) and the root-mean-square-error (RMSE) were used as comparison metrics. The average R2 was increased by 27.7% and 29.3% for training and testing, respectively, based on the fuzzy model. Using the proposed strategy in this work (integration between fuzzy logic and PSO) may increase the overall performance of the compression ignition engine by 2.065% and 8.256%, as concluded from the experimental tests and RSM.

Increasing air pollution and implementation of stricter emission regulations led to the research for the clean combustion concept of combustion engines. To resolve this concern, it is important to look for a clean and stable combustion concept that can adapt easily to an old existing engine as well as newer engines. The present study was performed to investigate the combustion stability and emission for blends of methanol (M), ethanol (E), and butanol (B) to evaluate the effect of their inherent oxygen content. Alcohol blends were prepared for two different oxygen mass fractions of 2.5% and 5% oxygen, m/m (defined as M2.5, E2.5, B2.5 and M5, E5, B5). For this, different volume fraction of respective alcohol was required (M2.5 and M5 contained 5.2% and 10.3% methanol respectively, E2.5 and E5 contained 7.4% and 14.8% ethanol respectively, B2.5 and B5 contained 11.7% and 23.3% butanol respectively).Detailed combustion analysis was performed for the alcohol blends (2.5% and 5% oxygen mass fraction) using the parameters like cycle-to-cycle analysis, coefficient of variation, combustion phasing etc. M5 showed the better stable combustion considering the lowest coefficient of variation for CA50 and indicated mean effective pressure. Moreover, the performance of E5 showed improved efficiency with brake thermal efficiency (BTE) of 27.94% and reduced brake specific fuel consumption. Significant reductions in hydrocarbon (HC), smoke and carbon dioxide (CO 2 ) emissions were recorded for 2.5% and 5% oxygenated condition. M5 showed lowest emission level among tested fuel with 20% lower oxide of nitrogen (NO) and 50% lower HC.
