<p>A fuel injection controller includes an oxygen sensor (33) for responding to an oxygen concentration inside an exhaust passage (43), and an injection amount control unit (50) programmed to control a fuel injection amount based on the output of the oxygen sensor (33). The injection amount control unit (50) includes an injection amount correction value computing unit (66) for determining an injection amount correction value (C) based on the output of the oxygen sensor (33), a short-time learning value computing unit (67) for determining a short-time learning value (S) based on the injection amount correction value (C), a long-time learning value computing unit (68) for determining a long-time learning value (L) based on the short-time learning value (S); a feedback correction amount computing unit (65, 71) for computing a feedback correction amount, an injection amount control value computing unit (69) for computing a control value of the fuel injection amount, and a long-time learning value holding unit (52N) for holding the long-time learning value (L).</p> |
