Abstract
A fuel injection pressure at a timing at which an NOx concentration (combustion temperature) indicates a maximum value under the condition that a fuel injection timing is fixed to a first injection timing is recorded as a first NOx peak injection pressure. Similarly, a second NOx peak injection pressure is recorded under the condition that the fuel injection timing is fixed to a second injection timing. A cetane number and distillation property of fuel are determined on the basis of these NOx peak injection pressures.
