“…This study examined the optimization of noise reduction at the engine and its exhaust with biodiesel blend, load, and compression ratio of the engine as input parameters. Analysis was carried out utilizing the Taguchi method, and optimization of the input parameters was performed by using SNR [10,11]. The experimental results obtained by Minitab were validated by an ANN.…”

Biodiesel is a renewable, biodegradable, and efficient fuel that can be blended with petro-diesel in any proportion. The noise in the engine resulting from the combustion has a direct effect on the engine’s performance. Many studies have examined the engines’ vibration and noise when using diesel and biodiesel blends. This study examines the optimization of diesel blends, load, and compression ratio in the aspect of reducing noise on a Kirloskar single-cylinder diesel engine. Noise was measured at the engine and its exhaust on a computerized setup and for different loads. The experimental results showed that a blend with 15% biodiesel, at 7kg load, and 18 compression ratio produced the lowest noise. Moreover, the Taguchi method was utilized, and experimental results were validated by an ANN

“…The vibration signature was noticed less for biodiesel fuel blends than ordinary diesel oil. Since the combustion effectiveness of biodiesel blends were superior to neat diesel fuel as a result of having greater cetane number (fuel quality), lower delay in the ignition, and a lot of oxygen accessibility [20,21]. Thus, the total burning happens and results in the lesser tendency of knock.…”

The purpose of the present study is to estimate the vibration and noise intensity of a single-cylinder direct injection diesel engine. The experiment was performed by varying the fuel injection pressures (FIP) such as 200 bar, 220 bar, and 240 bar respectively with four test fuel samples of Moringa oleifera oil biodiesel blends; BD0D100, BD10D90, BD20D80, and BD30D70. The intensity of vibration and noise has come down with the blends of Moringa oleifera biodiesel than regular diesel fuel (BD0D100). Besides, the increase in FIP looked at lower levels of vibration and noise disregarding fuel blends. Both the vibration and noise intensity was seen least with the BD20D80 fuel blend than leftover samples. The slightest RMS velocity and RMS noise were seen by 0.104 m/s and 39.71 dB correspondingly for BD20D80 than ordinary diesel at a FIP of 240 bar. Hence, the compression ignition engine can be operated with the BD20D80 fuel blend devoid of any amendment in the engine for the inferior vibration and noise.

“…Due to the overwhelming increase in petrol fuels demand globally, the search for alternatives fuels is critical to avoid the scarcity of fuel source. Biodiesel, as an alternative to fossil fuels, can be utilized as vehicle fuel without major modification in diesel engine [3,4]. Biodiesel is the most promising alternative for vehicle fuel as studies reported that biodiesel is environmentally friendly, easily biodegradable and renewable [5,6].…”

Microbial biodiesel is converted from microbial lipids via transesterification process. Most microbial biodiesel studies are focusing on the use of microalgal lipids as feedstock. Apart from using microalgae for lipid biosynthesis, lipids can also be extracted from other oleaginous microorganisms like fungi and yeast. However, there are gaps in the studies of lipid production from filamentous fungi, especially in-situ transesterification process. The aim of this project is to compare in-situ with the ex-situ transesterification of fungal biomass from Aspergillus oryzae. In ex-situ transesterification, two methods of lipid extraction, the Soxhlet extraction and the Bligh and Dyer extraction, were performed. For in-situ transesterification, two methods using different catalysts were investigated. Base-catalyzed in-situ transesterification of fungal biomass resulted on the highest Fatty Acid Methyl Esters (FAME) yield. The base-catalyzed in-situ transesterification was further optimized via Central Composite Design (CCD) of Response Surface Methodology (RSM). The parameters investigated were the catalyst loading, methanol to biomass ratio and reaction time. The optimization showed that the highest FAME yield was at 25.1% (w/w) with 10 minutes reaction time, 5% catalyst and 360:1 of the ratio of the methanol to biomass. Based on Analysis of Variance (ANOVA), the model was found to be significant according to the value of “Prob >F” of 0.0028. Copyright © 2021 by Authors, Published by BCREC Group.
