“…The simplest method for the preparation of aluminum nanoparticles is the sol‐gel method. It consists of four stages 19 Step 1 (Solution preparation) : Aluminum nitrate solution (0.5 M) is dissolved in 50 mL of deionized water (H 2 O) at 22°C and continuously stirred magnetically. Step 2 (Gel formation in the prepared solution) : Urea (0.05 M) is dissolved in the prepared solution and stored for 30 minutes before pH level 2 is reached. Step 3 (Gel growth particles) : Titration is carried out with a mixture of 0.1‐M NaOH and 25‐mL H 2 O until the pH level of 6 is reached. The formation of a clady gel at pH level 8 is accomplished by the addition of NaOH solution to the base solution. Step 4 (Agglomeration) : It is dried and calcined at 150°C for 12 hours.…”

This study aims to evaluate the thermal performance and friction factor characteristics of the U‐shaped serpentine microchannel heat sink using three different nanofluids. Two distinct nanoparticles, namely Al2O3 (alumina) and CuO (copper oxide), were used for the preparation of nanofluids using water and ethylene glycol (EG) as base fluids. Three nanofluids, namely nanofluid I (Al2O3 + water), nanofluid II (CuO + water), and nanofluid III (CuO + EG), have been prepared. The results showed that the thermal conductivity of nanofluids was increased for all concentrations (from 0.01 to 0.3%), compared with base fluids. The theoretical values derived from the relationship between the Darcy friction factor showed a clear understanding of the fully developed laminar flow. Thermal resistance for nanofluid III was lower than other nanofluids, resulting in a higher cooling efficiency. The nanofluid mechanism and the geometry of the U‐shaped serpentine heat sink have led to the improvement in the thermal performance of electronic cooling systems.

“…It is clear that BTE is higher by 20.33% for retarded timing and lower by 9.26% for advanced timing in the same engine. The improvement in efficiency is caused by the quick start of combustion with continuous burning in power stroke as well [16,17].…”

“…The reduction in flame quenching temperature and energy available with exhaust gas as specific heat causes for this behavior. The energy is much higher than intake air resulting in lower chamber operating temperature and increased HC emission [17]. Figure 4(d) shows the variation of NOx emission from engine with respect to brake power for standard, advanced and retarded injection of WPO fuel.…”

The disposal of waste plastic solids are becoming more than a crisis with respect to environmental safety. Proper disposal system may either be very expensive or leads to side effect. Hence researchers are looking for suitable methods to reuse them. Oils as substitute for petroleum products in internal combustion engines are gaining focus in India, because of its potential to generate large scale employment and relatively low environmental poverty. The present work aims at utilizing this waste plastic oil in a low heat rejection retarded timing engine whose combustion chamber surface is coated with partially stabilized zirconia (PSZ) ceramic. The influence of fuel injection timing was studied to completely understand the waste plastic oil performance in low heat rejection engine. The results revealed great improvement in performance, and emission characteristics. As a compensation, NOx formation was slightly increased. Overall performance of the low heat rejection engine with waste plastic oil fuel was better with 14⁰ bTDC retarded injection time.

“…Addition of Al2O3 nano-additives at 25ppm and 50ppm fraction to PBD resulted in improved peak pressure which could be perhaps attributed to the improved thermal conductivity of the resulting nano-fuel mixture [9,4]. The higher thermal conductivity of nano-fuel causes the fuel combustion to begin earlier thus resulting in higher in-cylinder peak pressure.…”

The current research work emphases on analysing the characteristics of combustion, performance, and emissions of Polanga Biodiesel (PBD) fuelled single cylinder diesel engine with Al2O3 nano-additives added at concentration of 25 ppm and 50 ppm. The results were compared with the baseline diesel fuel at varying engine loads (25%, 50%, 75% and 100%) in a agriculture based single cylinder diesel engine of 17.5 Compression ratio at constant engine speed of 1500 rpm. Al2O3 nano-additives were blended with PBD using magnetic stirrer and ultrasonicator. Experimentation results revealed that, the nanoparticles addition in PBD improved the combustion and emission characteristics of base fuel due to higher surface area to volume ratio of nano-additives. Moreover, Al2O3 nanoparticles addition enhanced the brake thermal efficiency (BTE) and lowered the brake specific fuel consumption (BSFC) by 6.58% and 7.38% respectively. Subsequently, the emissions of HC, CO, NOx and smoke opacity were improved with the addition of fuel borne additives in PBD owing to improved combustion efficiency.
