Abstract

A controller for an internal combustion engine (1), wherein a final fuel injection amount (TAU) fed to the internal combustion engine (1) is calculated by using, as parameters, an intake pressure correction value provided by the addition of an atmospheric pressure variation amount as a difference between an atmospheric pressure PAbase at a reference point and an atmospheric pressure (PA) at a present point detected by an atmospheric pressure sensor (23) to an intake pressure (PM) detected by an intake pressure sensor (21) and an engine rotational speed (NE) detected by a crank angle sensor (22), whereby, since the atmospheric pressure variation amount is considered for the intake pressure correction value and reflected on intake pressure parameters, a suitable fuel injection amount is fed to the internal combustion engine irrespective of an atmospheric pressure variation to satisfactorily maintain the operating conditions of the internal combustion engine (1) so as to assure a drivability.
