Abstract: An exhaust gas purifying apparatus for an internal combustion engine, in which a NOx absorbing catalyst and a NOx concentration sensor for detecting a NOx concentration in exhaust gases of the engine, are provided in an exhaust passage of the engine. A rich spike for temporarily enriching the air-fuel ratio is performed, and an execution timing of the rich spike is determined based on a detected output from the NOx concentration sensor. Performing the rich spike is determined to be unnecessary during a reducing state period from the time the rich spike ends to the time a preset time period has elapsed, and is also determined to be unnecessary when a change tendency of the detected output is determined to be an output decreasing state where the detected output is decreasing.

Abstract: A control device includes a cylinder pressure sensor, a driving condition detector, a reference crank angle setter, a reference cylinder pressure calculator, an EGR ratio estimator, and a controller. The cylinder pressure sensor detects a cylinder pressure inside a cylinder. The driving condition detector detects a driving condition in an internal combustion engine. The reference crank angle setter calculates, according to the driving condition, a reference crank angle immediately before which mixture gas starts combusting. The reference cylinder pressure calculator calculates a reference cylinder pressure at the reference crank angle based on temperature characteristics of a heat capacity ratio of the mixture gas under a condition. The EGR ratio estimator calculates an EGR ratio based on a pressure difference between the reference cylinder pressure and the cylinder pressure at the reference crank angle. The controller controls the internal combustion engine according to the EGR ratio.
