Abstract
A device and method for controlling the amount of fuel supplied to an internal combustion engine as a function of operating characteristics such as the pressure in the intake manifold, the engine speed, coolant temperature and intake air temperature, where a load signal formed from pressure and engine speed values is corrected by a correction factor F.sub.CORR as a function of the temperature, and when forming the correction factor F.sub.CORR, the influences of the engine temperature and/or the intake air temperature on the load sensing are weighted separately as a function of the operating point.
