“…One of the methods of modifying biofuel is that by adding additive into it [9]. Even though there were various additives that can be used in biodiesel fuel, nanoparticles as an additive in biodiesel had shown several advantages when used in the diesel engine [10][11][12]. Addition of nanoparticles into biodiesel can aid in giving better properties of the biodiesel fuel.…”

Evaluation of combustion characteristic, engine performances and exhaust emissions of nanoparticles blended in palm oil methyl ester (POME) was conducted in this experiment using a single-cylinder diesel engine. Nanoparticles used was aluminium oxide (Al2O3) and silicon dioxide (SiO2) with a portion of 50 ppm and 100 ppm. SiO2 and Al2O3 were blended in POME and labelled as PS50, PS100 and PA50, PA100, respectively. The data results for PS and PA fuel were compared to POME test fuel. Single cylinder diesel engine YANMAR TF120M attached with DEWESoft data acquisition module (DAQ) model SIRIUSi-HS was used in this experiment. Various engine loads of zero, 7 N.m, 14 Nm, 21 N.m and 28 N.m at a constant engine speed of 1800 rpm were applied during engine testing. Results for each fuel were obtained by calculating the average three times repetition of engine testing. Findings show that the highest maximum pressure of nanoparticles fuel increase by 16.3% compared to POME test fuel. Other than that, the engine peak torque and engine power show a significant increase by 43% and 44%, respectively, recorded during the PS50 fuel test. Meanwhile, emissions of nanoparticles fuel show a large decrease by 10% of oxide of nitrogen (NOx), 6.3% reduction of carbon dioxide (CO2) and a slight decrease of 0.02% on carbon monoxide (CO). Addition of nanoparticles in biodiesel show positive improvements when used in diesel engines and further details were discussed.

“…Also, results showed that the combustion duration, HC, smoke, CO, and brake specific fuel consumption reduced by 10%, 28.72%, 22.84%, 48.43%, and 11.65% respectively, whereas, the level of NO X increased by 11.27%. Srinidhi et al used nickel oxide (NiO) nanoparticle dispersed in neem oil–blended diesel fuel. The concentration of NiO in the fuel is varied from 25 to 100 ppm and three different injection timings are analyzed on the basis of emission and performance characteristics.…”

Effect of using plastic nanofuel as a fuel in a light‐duty diesel engine

et al. 2019

A novel nanofuel is formulated using aluminum oxide (alumina) nanoparticles (AONs) in neat plastic oil (PO). A light-duty compression-ignition engine is used in the present investigation to analyze the effect of a 100% plastic nanofuel under different concentrations of nanoparticle on performance, combustion, and emission characteristics. The modified fuels used for conducting the experiment were formulated by mixing PO with 100, 150, and 200 mg/L of AON. The results of the physical and chemical properties of neat PO were significantly improved, in addition to AON. The nanofuels exhibited lower in-cylinder pressure, delay period, and combustion duration than that of neat PO operation. The performance analysis revealed a 10.3% increase in thermal efficiency for PAN200 nanofuel compared with PO and it was almost the same as that of conventional diesel fuel. The emission levels of HC, CO, and smoke for PO-based nanofuels were reduced significantly at all brake mean effective pressure values, whereas the reduction in the NO X emission was only marginal. At full load, the emission of smoke, HC and CO of the PAN200 nanofuel were lower than the diesel operation. Overall, the engine fueled with nanofuel exhibited superior characteristics compared to that of neat PO operation.combustion, diesel engine, emission, nanoaluminum oxide, nanofuel, plastic oil | INTRODUCTIONThe high performance, durability, and wide range of applications of diesel engines are the major reasons for the rapid increase in their number, especially in the last two decades. Even though compression-ignition (CI) engines produce higher brake thermal efficiency (BTE) compared with spark-ignition engines, the level of NO X , smoke, and particulate matter in their exhaust is high. Recent studies reveal that the emission from the transportation sector contributes more to the total emission level than the industrial and domestic sectors. 1,2 The products of combustion pose a great threat to both human and animal life and are major environmental concerns. Reducing the exhaust emissions of diesel engines, without compromising the performance, is still a challenge for researchers. Also, emission norms are getting more stringent every year for reducing the impact of emissions on the environment. Moreover, excessive extraction and generous consumption are declining the level of fossil fuel reserves at an alarming rate. These two issues have forced researchers to look for an alternative environment-friendly energy source. 3,4 Extensive research is underway, around the world, for finding out a potential alternative energy resource for substituting petroleum fuels. The physical and chemical properties of various biodiesels are almost similar to that of conventional fuels, so the majority of the research has been carried out using them as an alternative for diesel. 5-9 Amongst the various fuels used, plastic oil (PO) synthesized using the pyrolysis technique has gained significant attention due to its double advantage by collecting waste plastic by recovering energy ...

“…The start of fuel injection timing also affects ecological engine indicators. In pursuit of the maximum energy efficiency of the engine, the beginning of fuel injection should be brought forward to a certain limit, and specific injection strategies and pressure can be carried out [30][31][32]. However, having the excellent start of fuel injection, the combustion takes place in a smaller volume, closer to the upper point of the piston.…”

“…However, having the excellent start of fuel injection, the combustion takes place in a smaller volume, closer to the upper point of the piston. This fact increases the combustion temperature and pressure, resulting in higher nitrogen oxide (NO x ) content forming in the cylinder, reduced opacity, and hydrocarbon (HC) emissions [32][33][34][35].The comparison of brake-specific fuel consumption (BSFC) and engine efficiency η e of engines allows for the most objective assessment of energy indicators of the internal combustion engine [31,36,37]. These indicators enable comparing engines of different structures during their running on fuels of various composition.The main harmful components of exhaust gases of engines are products of incomplete combustion (carbon monoxide (CO), incompletely burnt HC, smoke) and NO x [31,38,39].…”

Internal Combustion Engine Analysis of Energy Ecological Parameters by Neutrosophic MULTIMOORA and SWARA Methods

The investigation for new innovative solutions to reduce transport pollution is a priority for the European Union (EU). This study includes energy and a sustainable environment, as well as transport, logistics, and information and communication technologies. Energy ecological parameters of internal combustion depend on many factors: fuel, the fuel injection time, engine torque, etc. The engine’s energy ecological parameters were studied by changing engine torques, using different fuels, and changing the start of the fuel injection time. The selection of the optimum parameters is a complex problem. Multicriteria decision-making methods (MCDM) present powerful and flexible techniques for the solution of many sustainability problems. The article presents a new way of tackling transport pollution. The analysis of the energy ecological parameters of the experimental internal combustion engine is performed using the neutrosophic multi-objective optimization by a ratio analysis plus the full multiplicative form (MULTIMOORA) and step-wise weight assessment ratio analysis (SWARA) methods. The application of MCDM methods provides us with the opportunity to establish the best alternatives which reflect the best energy ecological parameters of the internal combustion engine.
