Abstract
An exhaust gas recirculation apparatus includes: a fresh air throttle portion that continues from a fresh air inlet portion and is configured to throttle the flow of fresh air; an inner side tube portion that continues from the fresh air throttle portion, has a tubular shape and has an opening end disposed on a side opposite to the fresh air throttle portion; an exhaust gas inlet portion configured to receive a flow of exhaust gas; a surrounding portion that continues from the exhaust gas inlet portion, surrounds the inner side tube portion, and defines a circumference direction flow path for the exhaust gas extending along an outer circumference surface of the inner side tube portion; and an outlet portion that continues from the surrounding portion, has a tubular shape, and defines a merging flow path configured to receive the flow of the fresh air flowing out from the opening end of the inner side tube portion and the flow of the exhaust gas flowing out from the circumference direction flow path. An annular opening is defined between the opening end of the inner side tube portion and the surrounding portion, the annular opening extending along the opening end of the inner side tube portion and connecting the circumference direction flow path and the merging flow path.
