<p><P>PROBLEM TO BE SOLVED: To provide a control method for an exhaust emission control system and the exhaust emission control system, capable of reducing, in forced regeneration control of an exhaust emission control device such as a data map mesh number and data map number for multi-injection control while avoiding a torque shock that is a sudden fluctuation of generated torque. <P>SOLUTION: When the operating state of an internal combustion engine 10 is a high-load operating state in forced regeneration control of the exhaust emission control device, general injection control in which multi-injection is stopped is performed. Further, the control area is divided to a multi-injection control area Rm, a transitional area Rt and a general injection control area Rn according to the rotating speed Ne and load Q of the internal combustion engine 10, and injection control data Ft(i) obtained by interpolation of injection control data Fml(i) on the multi-injection control area Rm side and injection control data Fnl(i) on the general injection control area Rn side is used in the transitional area Rt. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
