Turbulent Combustion Modeling in Compression Ignition Engines

Numerical analysis of injection parameters influence on diesel engine performances and emissions correlated by maximum in-cylinder pressure

“…Calculated values of [O 2 ], [CO] and [CO 2 ] are taken from the exhaust volume (region 3). Figure(2) represents calculated and measured averaged in-cylinder pressure evolutions as well as the heat released[21]. Calculate mean in-cylinder pressure lie perfectly on the measured one.…”

“…Cases treated concern five loads at engine speed of 1500 rpm. The engine has been widely explored by a great number of experimental and numerical studies as well as combustion-turbulence interactions [20][21][22] extraction of NOx and NO correlations [20], improving engine performances and reducing NOx levels using biofuels, animal fat emulsions [25], natural gas [26] and biogas [27]. The engine specifications are regrouped in table (1).…”

“…In the present work, algebraic relationships for CO, NO and NOx concentrations calculated exactly at the exhaust phase start have been established. Because of his cetane number (~50) C 7 H 16 is suggested as fuel for diesel engine simulations [1], [2], [20][21][22]. Indeed, exhaust phase occur to late diffusion combustion characterized by equilibrium combustion where [CO], [NO] and [NOx] seems to be constant.…”
