Role of combustion derived magnesia nanoflakes on the combustion, emission and functional characteristics of diesel engine susceptible to palm oil biodiesel-diesel blend

Abstract

This research article intends to discuss on the role and effects of dispersing solution combustion derived magnesia nanoflakes (~17 nm) within the biodiesel-diesel blends and pure diesel termed as nanofuels, in order to investigate the functional and pollutant emissions of a single-cylinder, electrically loaded, water-cooled diesel engine. The fuels focussed in this study are a blend of palm oil biodiesel and regular diesel dispersed with 50 ppm magnesia nanoflakes, and a pure diesel dispersed with 50 ppm magnesia nanoflakes. These fuels are compared with regular diesel which is considered as the base reference fuel, as well as with the biodiesel-diesel blend. From the experimental measurements, we inferred that the fuel density, viscous nature, and calorific value enhanced with the addition of nanoflakes. As for the engine performance attributes, the brake specific fuel consumption (BSFC) is lessened by 3.08% and 2.88% for particle dispersed biodiesel-diesel blend and particle dispersed diesel, respectively, whereas the brake thermal efficiency (BTE) enhances by 5.04% for particle dispersed biodiesel-diesel blend and 2.74% for particle dispersed diesel. With reference to emission, the unburnt hydrocarbon (UHC), white damp (CO), particulate exhaust or smoke, and the nitrogen oxides (NOx) are reduced by 9.51%, 18.71%, 13.64%, and 5.63%, respectively for particle dispersed biodiesel-diesel blend and 10.35%, 16.54%, 13.64%, 19.47%, and 4.70%, respectively for particle dispersed diesel.

Optimization of CeO2 and MgO nano‐particle‐added mango seed biodiesel blends using hybrid deep belief network‐coupled sandpiper optimizer

“…However, the MSME20 blend reduced NO X and CO emissions, and performance on unburned hydrocarbons (HC) and smoke emissions was significantly higher due to its poor burn rate caused by a slightly higher ignition delay 10 . Chandrasekaran et al 50 and Pan et al 51 introduced MgO and CeO 2 metal nano‐particles to overcome these combustion problems in palm oil and methanol based biodiesel blends. Therefore, in this study, 99% pure magnesium oxide (MgO) and cerium oxide (CeO 2 ) nano‐particles of 50–200 nm size were purchased from Nano Wings Private Limited, Khammam, Telangana.…”
