摘要：It is an object of the present invention to improve a fuel consumption and avoid an engine oil dilution compatible, at a time of renewal of an exhaust gas purification device 50. An exhaust gas purification system of the present invention is provided with the exhaust gas purification device 50 which is arranged in an exhaust gas route 77 of a common rail type engine 70, and is structured such that a plurality of renewing modes which burn and remove a particulate matter deposited within the exhaust gas purification device 50 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 50 by a post injection E regardless of a clogged state of the exhaust gas purification device 50, in the case that an accumulated drive time Te of the engine 70 becomes equal to or more than a previously set time T0.
