“…The characterization and optimization of Calophyllum inophyllum−Ceiba pentandra oil were investigated by Ong et al 27 ANN and ACO techniques were used to optimize the process variables such as the methanol−oil ratio, catalyst concentration, and reaction time on biodiesel yield. The recent challenges and opportunities in the production of biodiesel derived from agricultural products and microalgae using ionic liquids were reviewed by Ong et al 28 Transesterification using microwave irradiation on the synthesis of biodiesel produced from Ceiba pentandra oil was optimized by Silitonga et al 29 The performance and emission characteristics of biodiesel−bioethanol and diesel blends in diesel engines using the K-Extreme learning method were studied by Silitonga et al 30 The influential effect of different Mimusops elangi methyl ester (MEME) fuel blends on the performance, emission, and combustion parameters of a DI diesel engine was studied by Krupakaran et al 31 In their study, the MEME was synthesized by the process of transesterification, and the test fuel blends were prepared with diesel in the volume of 10% (90% diesel− 10% MEME), 20% (80% diesel−20% MEME), 30% (70% diesel−30% MEME), 40% (60% diesel−40% MEME), and 100% MEME. The fuel properties were evaluated and validated with the limits of ASTM standards.…”

The rapid growth in industrialization steadily increased the energy demand. The world’s population ultimately depends on petroleum as a major share of fuel for transportation and industrialization. Even though it is widely used in various sectors, its emission into the atmosphere creates serious problems in the form of acid rain, smog, etc. This present experimental investigation highlights the utilization of Vachellia nilotica seed oil methyl ester (VNSOME) synthesized from Vachellia nilotica seed oil (VNSO) fueled in a diesel engine to assess the emission and performance characteristics. VNSOME is produced using the alkaline catalyst (NaOH) transesterification technique. Four different fuel blends of biodiesel, namely, VNSOME5, VNSOME10, VNSOME15, and VNSOME20, were prepared and fueled in an unmodified engine. The engine brake thermal efficiency is lower, the brake-specific fuel consumption (BSFC) using VNSOME20 is higher, and the temperature of exhaust gas emitted after combustion is increased. The thermal efficiency is reduced by 7.34% with increased BSFC and exhaust gas temperature (EGT) of 9.3 and 14.28%, respectively, as compared to diesel fuel. Similarly, using an optimized biodiesel blend (VNSOME20), the emission emitted such as HC and CO is reduced by 19.14 and 22.2%, respectively. However, the engine fueled with the VNSOME20 biodiesel blend increased the level of CO2 and NO x emitted into the atmosphere when compared to diesel fuel.

“…It also decreases the lifecycle emission of CO 2 . The reason for increase in BSFC is mainly due to lower calorific value of the biodiesel, whereas increase in NO x level are mainly due to presence of oxygen content, shorter ignition delay, and higher premixed combustion phase duration of biodiesel blends as compared with diesel . In the same way, many researchers fueled hybrid fuels in a CI engine and reported that it reduces significant amount of NO x level, smoke opacity, and particulate matter in contrast to diesel and biodiesel but at the cost of lower power output.…”

Akin to biodiesel, hybrid fuels are gaining attention as a substitute to petro‐diesel, because of low processing cost of fuel production, having comparable engine performance, and significantly lower amount of emissions. This study presents experimental investigations on production of biodiesel and hybrid fuels from waste cooking oil and analyzes its behavior in an existing CI engine without the alteration of fuel injection settings. The biodiesel was produced by transesterification process and hybrid fuels were prepared by 3‐phase titration method. The physico‐chemical properties of fuels were evaluated as per ASTM/EN standards and compared with petro‐diesel. Biodiesel, blends of biodiesel and hybrid fuels were then analyzed for engine performance, emission, and combustion characteristics at constant speed and variable loading conditions. Biodiesel blend B30 showed higher brake thermal efficiency, lower brake specific energy consumption, and lower exhaust emissions (except NOx level), whereas, hybrid fuels showed a significant reduction in NOx level and comparable other exhaust emissions (except unburnt hydrocarbon) at the cost of lower brake thermal efficiency when compared with diesel. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13112, 2019

Nowadays, rapid increase in vehicle population led to increase in demand of fossil fuel. Decrease in availability of crude oil made the researchers to find a renewable alternative fuel, biofuels. Methyl esters are preferred as alternative to petro‐diesel engines. The present experimental study of Mimusops elangi methyl ester (MEME) is used as biodiesel on single cylinder four stroke, direct injection air cooled diesel engine at a constant speed of 1500 rpm at various loads. The general optimum biodiesel blends 20MEME‐80D (20%MEME‐80%Diesel) with optimum of 25 ppm TiO2 nanoparticle additives were taken for the experiment. The injection pressure of the engine is varied from 180 bar to 240 bar in the steps of 20 bar. The results of experimental investigation reported that the change in injection pressure 220 bar with modified fuel (20MEME‐80D + 25 ppm TiO2 nanoparticle) shows better performance and emission characteristics in the diesel engine. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13146, 2019
