Abstract
A method of removing impurities from EGR by air blowing may include performing an air-blowing mode in which, when a current intake system pressure detected by a controller exceeds a target intake system pressure in an intake system, in which a mixture is supplied to an engine, a portion of the mixture, serving as compressed air, flows into an EGR path, through which a portion of exhaust, serving as EGR gas and flowing in the intake system and an exhaust system connected to the intake system, is supplied to the engine.
