Abstract
An exhaust purification system of an internal combustion engine provided with a heat and hydrogen generation device () and an exhaust purification catalyst () comprised of the three way catalyst. Heat and hydrogen generated in the heat and hydrogen generation device () is fed to the exhaust purification catalyst (). When an air-fuel ratio of the air and fuel made to burn in the heat and hydrogen generation device () is made a predetermined target set air-fuel ratio, the air-fuel ratio of the exhaust gas discharged from the engine is controlled to the target adjusted air-fuel ratio required for making the air-fuel ratio of the gas flowing into the exhaust purification catalyst () the stoichiometric air-fuel ratio.
