ABSTRACT:
A defect of prior art methods for controlling an internal combustion engine based on families of characteristics depending on pressure and rpm is that an air mass being taken in is a function of an air temperature in a cylinder and thus of heating in an intake section. This defect is corrected according to the invention by multiplying a basic fuel value taken from a basic family of characteristics by a factor having a denominator containing a correction temperature being determinative for heating-up the intake air in the intake section as a function of its temperature and of an air flow and being taken from a corresponding family of temperature characteristics.
