PURPOSE:To prevent car surging and irregurality in idling both from occurring, by installing a process, which finds a compensation factor sering as a reference value in a learning state of an idling speed range, and another process which adds such one compensating a partial cylinder compensation value to a final injection quantity. CONSTITUTION:There are provided with a process (a), finding a final injection quantity Qfin according to engine load and speed, a process (b), finding an each-time compensation value (g) on the basis of a speed variation deviation DDNEp, and a process (c) finding a partial cylinder compensation value Qp upon integrating the each-time compensation value (g) at every cylinder. Likewise, there are provided with a process (d), finding a compensation factor K5 being made so as to serve as a reference value in a learning state at a normally used idling speed range, and a process (e) adding such one compensating the partical cylinder compensation value Qp with the said compensation factor K5 to the final injection quantity Qfin and making it a compensation injection quantity Qfin'. Thus, an engine vibration is suppressible without what with generating car surging and what with making idling into irregularity. |
