    Abstract: An object of the present invention is to allow a supply amount of a reducing agent to be an appropriate amount in an exhaust gas purification apparatus for an internal combustion engine comprising a selective catalytic reduction catalyst which is arranged for an exhaust gas passage of the internal combustion engine and a supply device which supplies the reducing agent to the selective catalytic reduction catalyst. In order to achieve the object, the present invention resides in an exhaust gas purification apparatus for an internal combustion engine comprising a selective catalytic reduction catalyst which is arranged for an exhaust gas passage of the internal combustion engine and a supply device which supplies a reducing agent to the selective catalytic reduction catalyst, wherein an amount of the reducing agent supplied from the supply device is adjusted on the basis of such a characteristic that a multiplied value, which is obtained by multiplying a flow rate of an exhaust gas allowed to flow into the selective catalytic reduction catalyst per unit time and a concentration of the reducing agent contained in the exhaust gas allowed to flow out from the selective catalytic reduction catalyst, correlates with a surplus reducing agent amount.

    Abstract: In an exhaust gas purification apparatus (27) provided in an exhaust gas path (25) of an engine (12), it is an object of the present invention to shorten a pipe length of a bypass path (29) bypassing a purification catalyst (62, 63) as short as possible, thereby reducing initial costs. The exhaust gas purification apparatus (27) of the invention of the present application includes a purification casing (61) in which at least the purification catalyst (62, 63) is accommodated. The purification catalyst (62, 63) purifies exhaust gas from the engine (12). The purification casing (61) is integrally provided with the bypass path (29) separately from the purification path (28) in which the purification catalyst (62, 63) exists. The bypass path (29) makes the exhaust gas bypasses the purification catalyst (62, 63) without passing through the purification catalyst (62, 63).
