    摘要： The invention relates to a method for diagnosing a gas-permeable object, such as a catalyst (15) or a filter, that was removed from an exhaust gas tract connected downstream of an internal combustion engine, in particular removed from a motor vehicle. In order to obtain particularly precise information about a function of the catalyst (15), according to the invention, an end face of the catalyst (15) is subjected to a test medium of a defined composition, such as propane gas or carbon monoxide, through an opening (5) by means of a device (2) in order to measure a catalytic reactivity. At a position located downstream, a concentration of at least one reduced or oxidized constituent of the test medium is measured after having passed the catalyst (15) and/or a temperature of the object after being subjected to the test medium is measured. The invention further relates to a device (1) for diagnosing a gas-permeable object, such as a catalyst (15) or a filter, that was removed from an exhaust gas tract connected downstream of an internal combustion engine, in particular removed from a motor vehicle.

    摘要： A method and an arrangement for cleaning a particulate filter in a vehicle provided with an internal combustion engine is provided. The particulate filter is mounted in an operative position inside an exhaust muffler under normal operation of the engine. The method involves performing a cleaning process including disassembling and removing the particulate filter from a first end of the muffler; reversing and reassembling the particulate filter a cleaning position at the first end of the muffler; starting and operating the engine by controlling the engine speed according to a predefined cycle until a predetermined condition is fulfilled; and stopping the engine and returning the particulate filter to its operative position inside the exhaust muffler.

    摘要： A system and method for removing retentate from filters is disclosed, which utilizes pressurized and/or vacuum fluid through localized application. The disclosure describes a cleaning system and sequence of steps for carrying out the cleaning process, whereby, a fluid is directed to flow through a localized region of the filter media, thereby dislodging and removing accumulated retentate from the filter. In addition, the localized application of fluid flow allows for localized monitoring of the cleanliness of the filter with a high degree of spatial resolution. This filter retentate removal system and method is broadly applicable to a wide range of systems and processes ranging to engines and exhaust systems to production plants and equipment.

    摘要： An upstream cylinder (21) and a downstream cylinder (24) are fixedly mounted to a support member (19), and a filter cylinder (26) is provided mountably and dismountably between the cylinders (21) and (24). In consequence, only the filter cylinder (26) can be dismounted with the cylinders (21) and (24) left as they are on the support member (19), so that the maintenance operation of a particulate matter removing filter (28) can be performed easily. In addition, pressure conduits (32) and (33) and a pressure sensor (34) of a pressure detection unit (31) for detecting a clogged state of the particulate matter removing filter (28) are disposed at positions offset from a moving path (30) of the filter cylinder (26). In consequence, only the filter cylinder (26) can be easily mounted or dismounted without being obstructed by the pressure conduits (32) and (33) and the pressure sensor (34).

    摘要： Internal combustion engine exhaust filter devices and the like are regenerated by placement in a reclamation or burn-off furnace, raising the temperature to at least about 800° F. to 900° F. and conducting relatively low volumes of low pressure air through the filter media to combust entrapped particulates and other materials residing on the filter media. The reclamation furnace includes an afterburner for combusting materials discharged from the filter devices into the furnace chamber so that complete combustion of materials is accomplished before discharge from the furnace. The flow of combustion air for the filter devices is controlled by manifolding and valving connected to a source and the oxygen content of combustion air may be enhanced by a separate source of oxygen injected into the combustion air flow stream.
