The present work emphasized overall viability study of using waste transformer oil (WTO) and its combinations on a diesel engine. To accomplish this fuel samples were divided into three sets with different volumetric proportions. Each set is compared the others finally, reference regular diesel. After thorough characterization utilizing spectroscopic methods like CHNS analysis FTIR, performance emission evaluation was done one-cylinder It has been discovered that flash point, calorific value, viscosity WTO blends are more than fuel. have higher carbon content but Sulphur some similar functional groups as According to evaluation, engine capable operating even when fueled raw WTO. Among all tested, WTO20 BD10D70 shows most satisfactory result. brake thermal efficiency WTO20BD10D70 almost fuel, while BSFC BSEC found be only 4.73% 3.46% respectively. exhaust gas temperature 8% lower However, HC 20% CO NOx emissions 14% 4.75% So, sample code can recommended substitute for

Abstract The global supply chain has been growing strongly in recent years. This development brings many benefits to the economy, society, and human resources each country but also causes a large number of concerns related environment since traditional logistics activities have releasing significant amount emissions. For that reason, solutions proposed deal with these environmental pollution problems. Among these, three promising are expected completely solve problems every chain: (i) Application blockchain chain, (ii) Use renewable energy alternative fuels, (iii) Design closed chain. However, it seems lack comprehensive study aiming overcome drawbacks logistics. Indeed, this work focuses on analyzing evaluating above-mentioned impacts solution solving More importantly, identifies critical factors challenges such as policies, laws, awareness, risks found be remarkable difficulties shifting progress green Finally, directions for developing deploying logistics, shipping sectors toward decarbonization strategies net-zero goals discussed detail.

CFD letters, Journal Year: 2025, Volume and Issue: 17(9), P. 13 - 29

Published: March 31, 2025

In the environmental context, air is seriously polluted, especially in developing countries. Among them, toxic exhaust emissions from internal combustion engines are one of sources with a large proportion. Many solutions have been applied, including using biofuel to replace traditional fuel, which has become popular worldwide. However, will be available depending on raw material source each country different origins. this study, we present application CFD (Computational Fluid Dynamics) theory simulate process diesel oil - vegetable mixture (coconut oil) through Kiva-3V software limit time and costs before proceeding conducting experiments determine appropriate mixing ratio between coconut as fuel for engines, improving engine performance reducing when oil. Research results AVL-5402 show that 5 15% gives low soot NOx emissions, lowest at 15%.

Production of biodiesel (isopropyl ester) from coconut oil by microwave assisted transesterification: parametric study and optimization

International Journal of Renewable Energy Development, Journal Year: 2024, Volume and Issue: 13(4), P. 662 - 672

Published: May 2, 2024

Biodiesel, a renewable fuel for diesel vehicle engines, has been commonly produced from transesterification process involving triglycerides vegetable oil with alcohol. One of the most promising candidates due to its abundance in Indonesia is coconut oil. However, short carbon chain present necessitates use longer-chain alcohol types adjust biodiesel chain, such as isopropanol. Therefore, this research focused on producing (isopropyl ester) using isopropanol and NaOH catalyst through process. To enhance process, microwave technology was utilized ability lower production reaction time conventional one-hour timeframe less than ten minutes, increase energy efficiency, improve quality. The primary objective investigate impact time, concentration, power isopropyl ester yield. Further optimization conducted Response Surface Methodology (RSM) Box-Behnken Design (BBD) illustrate model's effectiveness applicability. Based BBD simulation, optimal condition 1-minute 0.2 wt.% 443.9 W power, maximizing yield 99.89%. This highlights potential assisted reliability innovative approach, contributing development enhanced quality that meets specifications Indonesian National Standard (SNI).
