Measurements of spontaneous ignition lag have been conducted using mixtures of atomized kerosene and air at pressures from 1 MPa to 4 MPa under weakly vitiated conditions (18-19 O2%). Equivalence ratios very from 0.3 to 0.6. The apparatus is comprised of a preburner, a multiventuri fuel injector, a premixing tube of 45.2 mm in diameter and 200 mm in length, and an afterburner. The results shows that ignition lag can be expressed in terms of inlet air temperature T and pressure P, by the equation τig=A exp(E/RT)/P The activation energy E is close to 92 kJ/mol, being a half of the value for prevaporized kerosene/ air mixtures.
