ABSTRACT:
An internal combustion engine including a calculating device for calculating an amount of fuel to be injected on the basis of a pressure in an intake passage downstream of a throttle valve, a first correction device for calculating a transient correction value on the basis of a changing rate of the pressure and for correcting the amount of fuel on the basis of the transient correction value, a determining device for determining whether or not the recirculation of exhaust gas in an exhaust passage into the intake passage is started, or whether or not the recirculation is stopped, and a second correction device for reducing an absolute value of the transient correction value in accordance with an amount of recirculated exhaust gas when the determining device determines that the recirculation is started or stopped.
