Shock-tube investigation of self-ignition of n-heptane-air mixtures under engine relevant conditions

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.…”

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

“…This is illustrated in Fig. 3, showing experimental shock tube ignition delay results from Ciezki et al [26] at 13.5 bar pressure for stoichiometric mixtures of n-heptane and air as filled triangles. Similar experiments using n-decane as the fuel [27] produced ignition delay times very close to the n-heptane values in Fig.…”

“…In Fig. 3, we used experimental results [26,27] for stoichiometric fuel/air mixtures at 13.5 bar pressure to validate the present reaction mechanisms. The experiments demonstrated that for both the diesel and gasoline PRFs, below 650K and above 900K, the branched iso-alkane fuels show ignition delay times very close to those of the n-alkane fuels.…”

Global kinetics for n-heptane ignition at high pressures

“…10 at 40 atm and a stoichiometric n-heptane/air mixture. For n-heptane R is represented by C 7 H 15 , R' = C 7 H 14 and R" = C7H13.…”
