Abstract
In an exhaust gas purification apparatus for an internal combustion engine, reducing agent is diffused and the exhaust resistance is made small. The apparatus includes a reducing agent addition valve that injects reducing agent, a reducing agent addition valve mount portion that has a space in which the reducing agent addition valve injects the reducing agent outside a stream of exhaust gas flowing in an exhaust passage of an internal combustion engine and on which the reducing agent addition valve is mounted, and an impingement portion that is provided in the reducing agent addition valve mount portion and on which the reducing agent injected through the reducing agent addition valve impinges, wherein the direction of injection of the reducing agent from the reducing agent addition valve is oriented toward the impingement portion, and toward downstream of the reducing agent addition valve with respect to the exhaust gas flow.
