AGENT TANK FOR A SELECTIVE CATALYTIC REDUCTION SYSTEM WITH TWO RESPECTIVELY SOLID AND LIQUID COMPARTMENTS

摘要

The invention relates to a reservoir (1) for a reducing agent in a selective catalytic reduction system, the reducing agent being a water-based urea solution contained in a first compartment (1a), the urea being introduced into the water of the first compartment (1a) in the form of solid granules (10) containing predominantly urea from a second compartment (1b) by at least one passage (9a) in a partition (9) separating the first and second compartments (1a, 1b). The reservoir (1) comprises means for introducing (16) simultaneously into the first compartment (1a) by said at least one passage of a predetermined number of granules (10), the introduction means (16) being driven by an actuating element (17) between an open position in which the predetermined number of granules (10) passes into the first compartment (1a) and a closed position in which no granule (10) passes through the at least one a passage (9a).
