Cobalt chromite nanoparticle effects on kapok diesel emulsion performance and emission characteristics at various injection pressures B. Anbarasan, K. Muralidharan, C. Sakthi Rajan, T. Rajkumar Environmental Progress and Sustainable Energy, 2024 Alternative fuels derived from vegetable oil have great potential as diesel fuel replacements in the transportation and manufacturing sectors. The aim of this study is to use cobalt chromite nanoparticles as a fuel additive with biodiesel in engine and to experimentally investigate the influence of injection pressure on combustion parameters. As an addition, cobalt chromite nanoparticles are used with biodiesel made from kapok oil, which is blended with mineral diesel at a ratio of 20:80. The engine is operated at various injection pressures (200–260 bar) and with an 80 ppm nanoparticle concentration. The results have shown that the increased injection pressure caused by the use of nanoparticles enhances engine combustion properties, such as the peak pressure and the rate of heat release. The main purpose of this research was to investigate the effects of a CoCr2O4 + KME20 mix on a CI engine, with the hope of improving engine performance characteristics. This investigation examines the effects of varying test fuel injection pressures. The increased injection pressure of CoCr2O4 + KME20 resulted in better performance and combustion. The 240‐bar IP was shown to be superior to lower IPs because of its greater penetration length and more uniform formation. The IP rating of 240 bar represented a significant improvement over competing products with respect to emission controls. In addition to reducing our reliance on fossil fuels, this also prevents harmful chemicals from being released into the air.
INVESTIGATION OF THE PERFORMANCE AND EMISSION CHARACTERISTICS OF CEIBA PENTANDRA BIODIESEL BLENDS IN A VARIABLE COMPRESSION RATIO ENGINE R. Raja Sekar, R. Srinivasan, K. Muralidharan Transactions of Famena, 2022 In the current scenario, the production of biodiesel from non-edible oil is a promising way to overcome the problems associated with the energy crisis and environmental issues. In this research, non-edible biodiesel blends of B10, B20, B30, B40, and B100 methyl esters of Ceiba pentandra oil with standard diesel fuel are used to investigate the performance, combustion and emission characteristics of a variable compression ratio engine at different load conditions compared to diesel. The compression ratios 16.5:1, 17.5:1, 18.5:1 are employed in a 1500 rpm constant speed, single-cylinder with a variable compression ratio, direct injection, four-stroke diesel engine for experimental investigation. Performance and combustion characteristics such as brake specific energy consumption, brake thermal efficiency, net heat release rate and emission characteristics such as carbon monoxide, carbon dioxide, hydrocarbons and oxides of nitrogen are investigated. The biodiesel blend B10 and B20 showed optimal performance with fewer emissions.
Mechanical and Water Transport Characterization of Indian Almond–Banana Fibers Reinforced Hybrid Composites for Structural Applications Anand Sundararaju Perinbakannan, Muralidharan Karuppusamy, Karuppasamy Ramar Journal of Natural Fibers, 2022 In this investigation, hybrid composites were prepared for structural applications using Indian almond and Banana fibers by hand layup method. Five types of composites were fabricated viz. I-I-I-I, I-B-B-I, I-B-I-B, B-I-I-B & B-B-B-B and the mechanical & moisture absorption characteristics were studied. The tensile and flexural studies showed that the I-I-I-I composite displayed the maximum tensile and flexural strength of 61 MPa and 53 MPa, respectively, due to the placing of high strength Indian almond fiber at outer skin. The impact study resulted that the B-B-B-B composite exhibited the maximum impact strength (6.2 kJ/m2) owing to the presence of more void content (6.83%) that absorbed more impact energy. The moisture absorption study reported that the B-B-B-B composite absorbed the maximum moisture percentage of 21% at 11 days due to more void content whereas the I-I-I-I composite showed least moisture absorption of 15% at 11 days because of low void percentage. Further, the biodegradation study revealed that the B-B-B-B composite exhibited the maximum weight loss of 38% at 60 days due to more moisture absorption that weakened the bonding strength of matrix and fiber and the microorganism accelerated the degradation.
