Abstract
In an internal combustion engine having an amount of fuel injection controlled in relation to pressure in an intake pipe, a low pass filter is connected to the output side of an intake pipe pressure sensor so as to remove a pulsating component of the intake pressure. A second low pass filter is provided so as to compensate for the delay in response of such filter, and the outputs of both filters are calculated by a calculating unit.
