A rapid compression machine investigation of oxidation and auto-ignition of n-Heptane: Measurements and modeling

Kinetic modeling of gasoline surrogate components and mixtures under engine conditions

“…The recent modifications improved the agreement on a wide range of pressure moving from 3 up to nearly 50 atm covering both the high and the low temperature 8 reaction domain. In particular this new version of the model is a solid step in the direction of mimicking the strong dependence of ignition delay times on pressure evidenced by many experimental evidences for these fuel components [15][16][17][18][19][20].…”

“…octane) [9][10][11][12][13][14], toluene [15][16] and 1-hexene [17] in a wide range of operating conditions. Data collected in shock tube and rapid compression machine at stoichiometric conditions in air.…”

Experimental and modeling investigation of the low-temperature oxidation of n-heptane

“…The oxidation of n-heptane was previously studied in engines [1][2][3][4][5] and in several types of laboratory reactors such as shock tubes [6][7][8][9][10][11], rapid compression machines [12,13], jetstirred reactors [14][15][16], flow reactors [17], and flames [18][19][20][21][22]. Most of these studies were carried out under conditions of high temperature oxidation (temperature typically above 800 K) and relatively little attention was paid to the low-temperature oxidation of n-heptane, especially regarding the characterization of oxygenated reaction products [12,13,[15][16][17].…”

“…Most of these studies were carried out under conditions of high temperature oxidation (temperature typically above 800 K) and relatively little attention was paid to the low-temperature oxidation of n-heptane, especially regarding the characterization of oxygenated reaction products [12,13,[15][16][17]. Low-temperature oxidation of hydrocarbons is of importance for the development of diesel and homogenous charge compression ignition (HCCI) engines as this particular chemistry triggers auto-ignition phenomenon [35], it is also responsible for other combustion phenomena such as cool flames and negative temperature coefficient (NTC).…”

“…Minetti et al performed an experimental study of the oxidation of n-heptane in a rapid compression machine [12]. They measured ignition delay times of stoichiometric n-heptaneair mixtures at temperatures ranging from 600 to 900 K and at high pressure (3-9 bars).…”
