'Joseph Marr'] Homogeneous Charge Compression Ignition (HCCI) combustion is a potential candidate for dealing with the stringent regulations on vehicle emissions while still providing very good energy efficiency. Despite the promising results obtained in preliminary studies, the lack of autoignition control has delayed…

The experiments were conducted on a modified two-cylinder diesel engine to investigate the effects of excess-air coefficient (λ) and intake temperature (T*in) of different blending ratios (volume ratio of gasoline in the blends) on the combustion and emission characteristics of a Partially Premixed Compression Ignition…

'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°…

Ignition Combustion with Hydrogen and Methanol Authors: ['Víctor\nM. Domínguez' 'Juan J. Hernández' 'Ángel Ramos' 'José Rodríguez-Fernández'] Renewable hydrogen and e-fuels, synthesized from captured CO2 and renewable H2, are feasible ways to achieve transport decarbonization, particularly in medium/heavy-duty…

'Viorica Ghisman' 'Farooq Sher' 'Paul B. Tchounwou'] Nitrogen oxides are considered significant pollutants because of their effects on ecosystems and human health. The amount of NOx emitted by internal combustion engines can be reduced, mostly by acting on the conditions in which combustion takes place, respectively by…

Autoignition delay experiments for the isomers of butanol, including n-, sec-, tert-, and iso-butanol, have been performed using a heated rapid compression machine. For a compressed pressure of 15 bar, the compressed temperatures have been varied in the range of 725–855 K for all the stoichiometric fuel/oxidizer…

Utilizing hydrogen as an environmentally friendly fuel in LTC engines, which are ultra-low emission engines, enhances efficiency and improves combustion phase control. This addresses environmental challenges posed by fossil fuels. Effective control of the combustion phase in LTC engines, considering factors like fuel…

The present work presents the comparative simulation of a diesel engine fuelled on diesel fuel and biodiesel fuel. Two models, based on tabulated chemistry, were implemented for the simulation purpose and results were compared with experimental data obtained from a single cylinder diesel engine. The first model is a…

Historically two stroke engine petrol engines find wide applications in construction of two wheelers worldwide, however due to stringent environmental laws enforced universally; these engines are fading in numbers. In spite of the tight norms, internationally these engines are still used in agriculture, gensets etc.…

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…
