摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control system for an internal combustion engine with a NOx catalyst and a filter in an exhaust passage, for minimizing the worsening of fuel economy with the execution of filter regeneration control and NOx reduction control.
SOLUTION: The exhaust emission control system calculates a degree of suppressing the worsening of fuel economy with the execution of filter regeneration control due to a reduction of an EGR gas amount introduced into an intake system for the internal combustion engine and a degree of accelerating the worsening of fuel economy with the execution of NOx reduction control. It executes a reduction of the EGR gas amount when the degree of suppressing the worsening of fuel economy with the execution of the filter regeneration control is higher than the degree of accelerating the worsening of fuel economy with the execution of NOx reduction control.
