Self-ignition of S.I. engine model fuels: A shock tube investigation at high pressure

Detailed chemical kinetic reaction mechanisms for primary reference fuels for diesel cetane number and spark-ignition octane number

“…Also shown for comparison is a curve showing comparable computational results for iso-octane. Experimental results for the same conditions for iso-octane by Fieweger et al [30] are shown as filled circles in the figure and agree very well with the mechanism results but are available only for the higher temperature regime. It is clear from Fig.…”

“…These computations were carried out for stoichiometric fuel/air mixtures with ON values of 0, 60, 80 and 100, all at 40 bar pressure. These results are compared with experimental measurements for the same conditions and PRF mixtures by Fieweger et al [30] in second residence time in these examples, 85% of the n-cetane is consumed at 600K, while about 60% of the fuel is consumed when the fuel is iso-cetane. In Fig.…”

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].…”

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].…”
