摘要： An exhaust gas purifying apparatus includes an exhaust pipe 2a for forming an exhaust way 2, and a catalyst disposed in the exhaust way 2 for purifying an exhaust gas. The catalyst includes the first honeycomb catalyst portion 3a and the second honeycomb catalyst portion 4a. The first honeycomb catalyst portion 3a has an outer circumferrencial surface for forming a blowing passage 200 with an inner circumferrencial surface of the exhaust pipe 2a. The radial cross sectional area in the catalyst region of the first honeycomb catalyst portion 3a is set in the 1/5-2/3 range with respect to the radial cross sectional area of a flowing way defined by the inwall surface of the first mounting position 3a placed in the exhaust way 2, with the first honeycomb catalyst portion 3a being removed.

摘要： An exhaust-gas purifying apparatus includes a mantle, a support, and a catalytic layer. The support is disposed in the mantle, and is formed as at least one shape selected from the group consisting of cylinder shapes and corrugated shapes. The catalytic layer is loaded on at least one of the surfaces of the support. Moreover, the support includes at least two support elements disposed in the axial direction of the mantle, and the two support elements neighboring in the axial direction of the mantle are disposed out of phase with each other in the peripheral direction of the mantle. The exhaust-gas purifying apparatus shows not only an enhanced exhaust-gas purifying ability but also high misfire resistance.

摘要： An exhaust-gas purifying apparatus includes an outer cylinder, a plurality of cylinder-shaped supports, and a catalytic layer. The cylinder-shaped supports are disposed in the outer cylinder, and have an outer peripheral surface and an inner peripheral surface. At least two of the neighboring cylinder-shaped supports contact with each other with the outer peripheral surfaces. The catalytic layer is loaded on at least one of the outer peripheral surface and inner peripheral surface of the cylinder-shaped supports. At least one of the cylinder-shaped supports has a ring-shaped cross-section with a cut-off, and is disposed in the outer cylinder in such an elastically deformed state that it expands in the centrifugal direction. Thus, the exhaust-gas purifying apparatus not only shows a high exhaust-gas purifying ability, but also is good in terms of the assemblage easiness. Moreover, the exhaust-gas purifying apparatus exhibits improved misfire resistance.
