Abstract

An exhaust gas purification system is provided with an exhaust gas purification device which is arranged in an exhaust gas route of a common rail type engine, and is structured such that a plurality of renewing modes which burn and remove a particulate matter deposited within the exhaust gas purification device is executed. One of the plurality of renewing modes is an initialization renewing (a forced renewing) mode which supplies a fuel into the exhaust gas purification device by a post injection regardless of a clogged state of the exhaust gas purification device, in the case that an accumulated drive time of the engine becomes equal to or more than a previously set time.
