An exhaust gas purification system having a diesel particulate filter to purify particulate matter in the exhaust gas G from a diesel engine, wherein a an exhaust gas passage prevention structure or the like is installed in portions where particulate matter in the exhaust gas is collected and accumulated easily, and, the temperature raises easily by the oxidation of accumulated particulate matter, in said diesel particulate filter. n The allows to avoid DPF melting damage or breakage, by equalizing the heat distribution of the diesel particulate filter (DPF) and preventing an abnormally high temperature from generating partially, and an exhaust gas purification system of excellent endurance can be provided. |
