The digital twin is leveraged by an optimizer that select adjustments that allow the unit to maintain combustor dynamics and emissions in compliance without seasonal...

...Saket Verma; Kuldeep Kumar; L. M. Das; S. C. Kaushik In the present work, hydrogen enrichment in biogas is studied as a potential approach to improve the performance and emission features of a biodiesel-biogas dual fuel engine. A single-cylinder diesel engine is modified to operate in dual fuel...

.... However, most studies miss the environmental impact and economy of alternative fuels, while focusing on performance and emissions characteristics of different alternative fuels. The present paper aims to introduce a novel perspective to evaluate fuels environmentally and economically. For this purpose...

... engine performance parameters and emissions has been investigated. A 1 L/min blend of HHO is fed to the engine as a secondary fuel and a constant electrical load, and variable engine speed (1300–2300) tests were carried out to quantify the foremost concentration of KOH in the fuel cell electrolyte...
