Abstract
In an exhaust gas purification apparatus of an internal combustion engine, there is provided a technique capable of suppressing a reduction in exhaust gas purification performance. The apparatus includes: an exhaust gas purification catalyst () that is arranged in an exhaust passage of the internal combustion engine for purifying an exhaust gas; an adsorption device () that is arranged at an upstream side of the exhaust gas purification catalyst, rises in temperature up to an upper limit temperature due to heat generated by adsorption thereto of an incoming first component, and falls in temperature after its temperature has reached said upper limit temperature; and a heat generating component supply unit () that supplies a second component which generates reaction heat in the exhaust gas purification catalyst, before the temperature of the adsorption device begins to fall.
