An EGR mixer has a mixing shell which defines a mixing cavity only on the down side, and does not define the mixing cavity on the up side. The EGR mixer has a primary internal opening for fresh air, which is formed so that an opening plane is inclined to a side so that the opening plane faces a secondary internal opening for exhaust gas. The primary internal opening and the secondary internal opening are arranged to allow exhaust gas to enter into the primary internal opening. The exhaust gas restricts a fresh air flow so that the fresh air flow creates increased vacuum. It is possible to suppress pressure loss and to increase an amount of exhaust gas. |
