Abstract
Provided is an exhaust gas filter, including: an external case connected with an exhaust pipe; a filtering unit provided in the external case; a filtering path supplying exhaust gas to the filtering unit; and a pressure relief flange provided in the external case to discharge exhaust gas by bypassing the filtering unit.According to an exemplary embodiment of the present invention, an exhaust gas filter can prevent the exhaust gas filter from being broken by circuitously discharging exhaust gas even when particular matters collected in the exhaust gas filter increase and thus, pressure in the exhaust gas filter excessively increasesFurther, engine components such as an EGR, a turbocharger, and the like can be prevented from being broken or outputs thereof can be prevented from deteriorating.
