'Zeineb Labiadh' 'Amsini Sadiki' 'Mouldi Chrigui' 'Antonio M. Scarfone'] The behaviors of spray, in Reactivity Controlled Combustion Ignition (RCCI) dual fuel engine and subsequent emissions formation, are numerically addressed. Five spray cone angles ranging between 5° and 25° with an advanced injection timing of 22°…

Multi-fuel compression ignition (CI) engines offer superior power density and fuel flexibility. However, achieving consistent and optimal combustion phasing across a wide range of operating conditions remains a major challenge, particularly in the presence of modeling uncertainties. This paper presents a novel…

This work aims to determine the optimal engine operating conditions for balanced combustion, performance and emissions characteristics with considerable reduction in smoke and nitrogen oxides (NOx). This work examined direct injected (DI) 30% mahua biodiesel-diesel as high reactive fuel (HRF) and port fuel injected…

To realize the potential of DME for clean combustion, fueling control is essential. In this research, the challenges, advantages, and applicability of high-pressure direct injection and low-pressure port injection are reviewed and evaluated, especially in relevance to HCCI combustion. In this study, emphasis is given…

In-cylinder flow structures and turbulence characteristics are investigated using direct numerical simulations (DNS) in a laboratory-scale engine at technically relevant engine speeds (1500 and 2500 rpm at full load). The data are computed for 12 compressionexpansion cycles at each engine speed with initial conditions…

'Christian Oliver Paschereit'] The "Shockless Explosion Combustion" (SEC) concept for gas turbine combustors, introduced in 2014, approximates constant volume combustion (CVC) by harnessing acoustic confinement of autoigniting gas packets. The resulting pressure waves simultaneously transmit combustion energy to a…

It has been discovered that there is a dynamic coupling between cycloalkanes and aromatics, which affects the number and types of radicals, thereby controlling the ignition and combustion of fuels. Therefore, it is necessary to analyze the effects of cyclohexane production in multicomponent gasoline surrogate fuels…

An amino acid ionic liquid, with lysine as the cation and CF₃SO₃⁻ as the anion, was synthesized by ion‐exchange between lysine and trifluoromethanesulfonic acid. This ionic liquid was then applied as a catalyst for the esterification of oleic acid with methanol to produce methyl oleate, commonly known as biodiesel.…
