Abstract
An exhaust gas purifying apparatus for an internal combustion engine includes a collector, which collects exhaust particles in exhaust gas discharged from the internal combustion engine. The exhaust gas purifying apparatus computes an amount of a predetermined gas component in the exhaust gas, which passes through the collector. The exhaust gas purifying apparatus computes a collected amount of the exhaust particles based on a pressure difference across the collector, based on a temperature of the exhaust gas, which passes through the collector, and based on the amount of the predetermined gas component. The exhaust gas purifying apparatus regenerates the collector by burning the exhaust particles collected in the collector when the collected amount reaches a predetermined value.
