Abstract: PROBLEM TO BE SOLVED: To provide an exhaust treating filter having an enhanced efficiency for arrangement. SOLUTION: The exhaust post-processing filter has a housing 22 between first and second ends 30 and 32 along the direction of an axis 28. The housing 22 has first and second ports 34 and 36 at the same first end. One of the ports is an inlet and the other an outlet. The housing 22 has an intermediate area 38 of a cross-sectional area A1 on the vertical plane of the axis 28 between the first and second ends. The intermediate area has an exhaust (catalytic) filter element 24 disposed therein to cover the cross-sectional area A1. However, a hollow portion 40 having a small cross-sectional area A2 is present inside, so the actual cross-sectional area A3 of the exhaust filter element is A1-A2. A transfer tube 26 communicates with the second port through the hollow portion. Exhaust flows through the exhaust filter element 24 between first and second side portions 44 and 46 in an axial direction 42 and flows through the transfer tube and the hollow portion in the opposite axial direction 48.

Abstract: An exhaust aftertreatment filter (20) includes a housing (22) extending axially along an axis (28) between distally opposite first and second ends (30 and 32), a first port (34) at the first end of the housing, a second port (36) also at the first end of the housing, one of the first and second ports being an inlet, and the other being an outlet, the housing having an intermediate section (38) between the distally opposite ends, the intermediate section having a given cross sectional area A1 along a sectional plane transverse to the axis, a catalytic exhaust filter element (24) in the intermediate section and entirely filling the cross sectional area A1 except for a smaller cut-out (40) in the exhaust filter element of cross sectional area A2, the exhaust filter element having a cross sectional area A3 = A1-A2, a transfer tube (26) extending through the cut-out and communicating with the second port. Exhaust flows axially (42) through the exhaust filter element between first and second distally opposite sides (44 and 46) of the exhaust filter element, the first side facing the first end of the housing, the second side facing the second end of the housing, exhaust flowing axially through the exhaust filter element in one axial direction (42) and flowing through the transfer tube and cut-out in the opposite axial direction (48).
