“…The CO and HC are decreased with jatropha biodiesel B08 application at variable load. Due to reduction in ignition delay period with biodiesel blend [21], it increases the engine ability for better and cleaner combustion hence; CO and HC emission are reduced. The variation for biodiesel blends B08 is compared with baseline diesel at rated load.…”

A significant increase in every nation’s energy demand and insufficient conventional energy reservoirs for long duration, there became necessary requirement to shift from non-renewable to renewable energy sources. Diesel and biodiesel fuels have different thermo physical properties; hence performance and emission output parameters are also different compares with each other. For effective utilization of biodiesel, the characteristics of conventional single cylinder diesel engine with changing load and static speed (1500 rev/min) conditions are evaluated. The baseline diesel, biodiesel - diesel (BD) B08 [8% biodiesel blended with diesel] and ethanol-biodiesel-diesel (EBD) E05B08 [5% ethanol and 8% biodiesel blended with diesel] by v/v ratio are used for experimentation. Brake thermal efficiency (BTE) reduced from 29.14% with diesel to 27.64% with biodiesel and 28.49% with ethanol blends. It is observed that BTE reduced by 1.5% with biodiesel blend and 0.65% only with ethanol blend. The CO, HC and opacity of exhaust gas pollutants are reduced with biodiesel blend fuel and also further reduced with EBD blend. NOx formation with B08 fuel is enhanced to 1967 ppm from 1557 ppm of baseline diesel whereas it is slightly increased to 1734 ppm by E05B08 fuel.

“…This study revealed that before oxidizing, the age of the soot particles was in the range of 0.2-1.0 ms and it also revealed that the initial size of the soot particles was in the range of 2-18 nm. This study failed to consider the effects of thermophoresis factor and effects of the coagulation process in their calculations (Ibrahim et al 2016;Nguyen et al 2020;Jagtap et al 2020).…”

It is essential to study the behaviour of soot particles in the engine cylinder, including movement and physical properties during engine operation, for further analysis of performance characteristics and engine emissions. This research aims to determine the size distribution of soot particles near the cylinder wall, leading to soot in lubricating oil. The research was carried out numerically using in-house MATLAB routines to post-process CFD simulation results. In this analysis, the soot particle size was calculated using the Hiroyasu soot formation, Nagle & Strickland-Constable oxidation, and Wersborg soot coagulation models. In addition, the simulation time and computing effort were minimized by using a post-processed soot particle size estimate. According to the findings, soot particles smaller than 50 nm were found in the squish area, especially near the cylinder wall. The average value of the final location of the particles tracked from all zones in the trajectory analysis varies between 0.4 and 3.1% of the magnitude closer to the cylinder wall relative to the particles tracked without the thermophoresis factor.

In this study, Taguchi design method supported by analysis of variance (ANOVA) was used to determine the optimum values of motor variables corresponding to optimum motor output. For the design, 1-heptanol ratio (HR), compression ratio (CR) and engine load were selected as engine variables, while the resulting brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) were selected as engine responses. Among the engine variables, three different values were selected as 0%, 5% and 15% for HR, 6.0:1, 8.0:1 and 10.0:1 for CR, 9, 18 and 27 Nm for load. According to the results, the optimum engine operating parameters required to obtain the best BTE and BSFC values were found to be 5% HR, 10.0:1 CR and 27 Nm load. BTE and BSFC based on optimum operating parameters were found to be 33.120% and 0.278 kg/kWh, respectively. When the results obtained from the optimization and the experimental results were compared, it was revealed that the optimization was successfully performed with an error of less than 10%.
