Popis: Dynamics of combustion processes of n-heptane and i-octane have been studied with varying temperature and pressure by means of a jet stirred flow reactor (JSFR), in the range 450–850K and 1 – 12 atm. Periodic or damped oscillatory cool flames, multistage ignitions, “jumps,” and slow combustion have been observed, and their regions of existence in the pressure/temperature plane have been mapped. Results indicate that ignition of n-heptane is possible at low temperatures and it is not strongly dependent on pressure. The behavior observed with i-octane at low temperatures is strongly dependent on pressure and give rise to ignition at pressures above ∼8 atm. At high temperature, spontaneous ignition occurs in both hydrocarbons and at pressures above ∼4 atm is feebly dependent on pressure.
