“…We shift and wash the hydroxide accelerator numerous times. After relocating the hydroxide accelerator and rinsing it with clean water several times, the pH of the filtrate is predicted to be around 7 17 . The resulting material is dried in a stove at 120°C for 16 h and then calcined at 600°C for 4 h, yielding a finely milled jasper green powder.…”

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.

“…Therefore, improved engine efficiency and an emission reduction can be achieved via an improved lubrication regime between the piston ring and cylinder liner. Refining the interaction between the piston/ring pack and cylinder liner in combination with using alternative fuels such as liquefied natural gas, methanol or biomethanol [8] and refining the combustion cycle [9] provides a viable route to meet environmental regulations. This article follows the work given in [10] on an RTX-6 Winterthur Gas & Diesel test engine in which a series of ultrasonic sensors were instrumented close to the top dead center (TDC) of the piston and three lubricant injection configurations were evaluated.…”
