PURPOSE: An apparatus for learning control of fuel injection when acceleration on a vehicle and method thereof are provided to stabilize the emission of nitride and to improve the responsiveness to acceleration by compensating the air-fuel ratio in the lean state. CONSTITUTION: A control unit detects the load change degree by reading the information of an acceleration pedal position detecting unit(S101). The load change degree is compared to a reference value(S102). If the load change degree is over the reference value, a request for acceleration is decided(S103). The satisfaction of a feedback completion condition with sufficient warming-up after starting is decided(S104). The amounts of oxygen included in the exhaust gas are averaged(S105). The average value is compared to the feedback completion condition(S106). If the average amount is less than the reference value, the fuel injection is increased(S107). Otherwise, the fuel injection is decreased(S108).
