“…It works well even at low engine loads (Uyumaz 2018). The emissions of the diesel engine would be substantially reduced by fuel injection, turbocharging, supercharging and also by the use of a perfect blend of biodiesel (Mustayen et al 2022). Nanoparticles emulsi ed with biodiesel shorten ignition delay, accelerate the early onset of combustion, reduce HRR, and lowers In-cylinder peak pressure at full load (Prabhu and Venkata Ramanan 2018).…”

The use of biodiesel can reduce dependence on diesel and stabilize the economy when using internal combustion engines. CI engine's performance with biodiesel is substantially low but could be improved by emulsifying nano-additives with biodiesel. Magnesium-doped Calcium Oxide, a novel nanocatalyst is emulsified in its nano form with the Sapindus Trifoliatus biodiesel (STBD) at B25 blend (STBD25+Mg-CaO 30ppm) and tested in the CI engine. The performance results obtained are compared to the baseline values obtained using diesel, Sapindus Trifoliatus biodiesel (STBD25), and Sapindus Trifoliatus biodiesel blended with Cao nano additives (STBD25+30ppm CaO) in the CI engine. . A maximum biodiesel yield of 91.75% was achieved at 58°C, 73 min, a catalyst concentration of 4% (%w / %w) and a methanol: oil molar ratio of 15:1. From the comparison, it is revealed that (i) In-cylinder pressure found to be increased by 3.22%, 6.24% and 9.02%, (ii) HRR increases by 1.68%, 16.69% and 32.5%, (iii) BTE is found to be increased by 4.56%, 8.23% and 11.79%, (iv) UHC decreases by 21.12%, 6.06% and 11.43%, (v) CO decreases by 0.04%, 0.01% and 0.01%, (vi) Smoke decreases by 54.52%, 9.34% and 19.58%, compared with diesel, STBD25+30ppm CaO and STBD25. NOx released while using STBD25+Mg doped CaO in CI engine was observed to decrease compared with STBD25 and STBD25+CaO (by 10.72 % and 18.64 %) and increase compared with diesel (by 8.64%). Whereas an insignificant drop in NOx was observed while using STBD25+Mg doped CaO as fuel compared with STBD25+CaO and STBD25 in spite of a significant increase in HRR and BTE which might be due to the capture of excess oxygen by Mg during the combustion diffusion phase.

“…Currently, the electricity in off-grid communities is still mostly supplied by centralized or decentralized diesel generators (2), even though the supplemental use of renewable energy from water, wind (3) and solar (4) is an increasing part of their energy mix. Additionally, centralized, or decentralized furnaces, based on fossil fuels or renewable fuels (e.g., wood), may be used to supply the heat needed for space heating and domestic hot water.…”

Today, off-grid communities rely mainly on diesel gensets with limited electrical efficiency and diesel furnaces for electricity and heat generation, respectively. The CO2 emissions associated with this electricity production can be reduced by improving the electrical efficiency of the system thus reducing the fuel consumption. Additionally, waste heat from the electricity production can be recovered for heating thus creating a combined heat and power system. In this work, a solid oxide fuel cell combined heat and power system hybridized to a battery was proposed for this purpose. Simulation of the annual electricity and heat production were performed using real temporal electrical demand data. Results showed that a reduction of up to 36 % in primary energy consumption can be reached compared with the current situation.

“…The deep concern of the researchers is to find alternative sources to improve engine performance and reduce pollutants. The ways that are observed for these two criteria (i.e., performance improvement and emitting less pollutants) of engines are as follows: (a) design upgrade via optimization of internal measurement parameters [2][3][4]; (b) implementation of aftertreatment techniques [5,6]; and (c) utilize biodiesels as alternative diesel fuels [4,7,8]. It was investigated that, as the ignition of fossil fuels is limited, the eco-friendly and less pollutant biodiesels can be the alternative to conventional fuels in diesel generation sectors [9].…”

Theoretical and Experimental Analysis of Engine Performance and Emissions Fuelled with Jojoba Biodiesel

Over many decades, isolated regions (e.g., islands, rural and remote areas) have heavily relied on diesel engine for producing power and energy. However, due to depleting fossil fuels and concerning emissions, biodiesels could be the substitute for diesel in power generation sectors. This study developed a single-zone thermodynamic model to predict the engine performances such as brake power (BP), torque, brake thermal efficiency (BTE), brake-specific fuel consumption (BSFC) and ignition delay (ID) times for diesel and jojoba biodiesel. The experiments were conducted on a fully automated, 4-cylinder, 4-stroke, liquid-cooled direct injection 3.7-L diesel engine fueled with diesel (D100) and three jojoba blends (JB5, JB10, and JB20) to validate the model. The performance simulation results agreed with experimental data for all tested fuels at 1200 to 2400 rpm speed and 25%, 50%, 75%, and 100% loading operation. The minimum error (3.7%) was observed for BP for D100 at 2000 rpm and 100% load, and the maximum error (19.2%) was found for JB10 at 1200 rpm and 25% loading operation. As load increases from 25 to 100%, the BSFC and torque difference between diesel and JB20 decreases from 10 to 6.5 and 9 to 6%, respectively. A shorter ID time was observed in JB5 compared to JB10 and JB20. Furthermore, a significant reduction was observed in CO (7.55%) and HC (6.65%) emission for JB20 at 25% and 1200 rpm compared to diesel fuel; however, NOx emission was increased up to 10.25% under any given conditions.
