摘要： An exhaust gas recirculation device for an internal combustion engine has a filter for trapping particulates in a recirculation gas, which is arranged in a recirculation gas route, and a device for generating a reverse air flow in which a pure gas flow for the reverse air flow passing through said filter in a reverse direction with respect to a recirculation gas flowing direction in the filter is generated. In the exhaust gas circulation device, the trapped gases are discharged out of the filter by the reverse air flow and are not returned into the internal combustion engine due to an engine exhaust pressure.

摘要： Filter has a filter main body, a container, a first counter room, and a second counter room. A counter air is introduced into the first counter room through the counter air discharge valve, and fine particles trapped in the filter main body are removed and transported to the second counter room. Then, the removed fine particles are further transported to a process portion isolated from an exhaust gas passage, and the fine particles are fired in the process portion. Since the process portion is isolated from the exhaust gas passage, the fine particles in the process portion are not returned to the filter main body. Moreover, since the fine particles are transported by the counter air only to the second counter room, it is possible to reduce an amount of the counter air.

摘要： A ceramic honeycomb catalytic converter having a novel canning structure capable of stably retaining a thin-walled ceramic honeycomb catalyst within a metal casing for a long period. A retainer member in the form of a ceramic fiber mat is disposed between an inner peripheral surface of the casing and an outer peripheral surface of the honeycomb catalyst, in a compressed state to generate a surface pressure for retaining the honeycomb catalyst in place. The ceramic fiber mat is composed of heat resistant and non-intumescent ceramic fibers, and has a compression characteristic which is substantially free from a significant increase or decrease over an operative temperature range of the catalytic converter. The casing may be provided with at least one locking member for locking the ceramic fiber mat in a flow direction of exhaust gas passed through the honeycomb catalyst.

摘要： A ceramic honeycomb catalyst includes a thin-walled honeycomb structural body (10) and a catalytic substance carried by the honeycomb structural body (10). The honeycomb structural body (10) has a number of longitudinally extending flow passages (13) defined by an outer peripheral wall (11) and partition walls (12) with a reduced thickness (t). The honeycomb structural body (10) satisfies particular relationships between the partition wall thickness (t) and the open frontal area (OFA) or bulk density (G). Notwithstanding the thin-walled partition walls, the honeycomb structural body (10) has practically satisfactory compressive strength characteristics. The catalyst comprising the honeycomb structural body (10) has reduced pressure loss and heat capacity.

摘要： An exhaust gas filter is provided, including a honeycomb structure having a plurality of partition walls defining through-holes extending along an axial direction. The through-holes include first and second groups. The first group is plugged via first sealing members at a second axial end of the honeycomb structure, while the second group is plugged via second sealing members at the first axial end of the honeycomb structure. The first group of through-holes is adapted to receive exhaust gas, and trap therein fine particles. The first sealing members have a three-dimensional micropore structure that includes interconnected pores to allow blowback air to pass therethrough. The blowback air flows through both the first sealing members and the partition walls defining the second through-holes so as to remove the fine particles that have collected in the first through-holes. Additionally, an apparatus is provided including the honeycomb structure and a device for receiving particles that are removed from the honeycomb structure via flow of the blowback air.

摘要： An undulated-wall honeycomb structure (1) has multiple cell passages (2) with mutually parallel passage directions. With this undulated-wall honeycomb structure (1), intersections (4) between walls (3) partitioning the cell passages (2) are formed at cross-sections perpendicular to the cell passages (2) and positioned systematically maintaining a predetermined pitch, and also the wall face portions (5) of the walls (3) excluding the intersections (4) are formed with undulated shapes in both the cell passage direction and the cross-section direction perpendicular to the cell passage direction. According to this undulated-wall honeycomb structure, advantages such as improved exhaust gas purification capabilities and catalyst capabilities, improved mechanical strength for canning, and further improved heat-resistant shock properties can be obtained.
