ABSTRACT:
Fuel injection controller is provided for an engine having a purge passage for purging fuel vapor from the fuel tank into the intake passage, a purge valve which opens and closes the purge passage and a mechanism for feedback correcting a fuel injection amount based on a detected air-fuel ratio. The controller comprises a device for detecting the fuel flowrate in the purge passage, a device for subtracting the fuel flowrate in the purge passage from the basic injection amount so as to correct the set injection amount, and a device for increasing a fuel feedback gain of the air-fuel ratio feedback correction. In this way, even if the air-fuel ratio feedback correction amount decreases due to purge, the air-fuel ratio feedback gain will not decrease and the response of the air-fuel ratio correction can be maintained.
