Abstract
The invention relates to a method for determining the ignitability of fuel, particularly of diesel, biodiesel, gas-to-liquid or biomass-to-liquid fuel, with an unknown fuel quality for an internal combustion engine. Provision is made for the density of the fuel to be ascertained and for the ignitability to be derived from this.
