摘要： An exhaust gas filter for Diesel engines that consists of a filter block made of a porous ceramic material, and a plurality of ducts extending through said filter block that extend in the flow direction of the exhaust gases. The ducts in each case are alternately closed at their upstream or their downstream end, whereby the exhaust gases are forced to penetrate a filtering separating wall between two ducts. The closing means at the downstream end, are arranged so that they are staggered with respect to one another in the flow direction; in particular they are staggered by about 5 to 150 mm. The staggered arrangement of the closing means reduces the danger of a thermal damage to the filter block during the burning-off of the deposited soot.

摘要： An exhaust gas filter for Diesel engines that consists of a monolithic filter block made of a porous ceramic material having a plurality of ducts extending in the flow direction of the exhaust gases, said ducts alternately being closed by plugs in order to force the passage of gas through the duct walls into adjacent ducts. In the case of this exhaust gas filter, the filter block is divided into zones having a decreasing porosity in the flow direction of the gases, and the plugs which force the passage of the gas through the duct walls are each arranged in the area of the zone border. Filters are preferred that have two to four zones of decreasing porosity. The exhaust gas filters are manufactured in that a filter blank that has the largest desired porosity is immersed in a solution or suspension of a porosity-reducing agent up to the desired zone border and is subsequently dried and is possibly burnt. Preferred agents for reducing the porosity are water glass solutions or cordierite suspensions.

摘要： A process and equipment for removing toxic and malodorous gases from the fresh air for vehicle cabins by catalytic oxidation, the process being based on passing the fresh air over a heating-system heat exchanger, the heat-emitting surfaces of which form the support for an oxidation catalyst. The heat exchanger used is the heating-system heat exchanger which is present in virtually all motor vehicles. In contrast to known solutions for purifying the fresh air, for example by means of activated carbon, the process is maintenance-free and does not require any additional constructional volume.

摘要： An exhaust-gas filter, for example a soot-particle filter, has a filter element which has inlet passages for the raw gas and outlet passages for the clean gas. In order as far as possible to prevent clogging of the filter over the running time caused by deposits on the filter walls, the raw-gas passages are configured with a larger cross-section than the clean-gas passages.

摘要： The quality of the external air is determined by means of a pollutant sensor. The quality of the internal air is determined by calculation taking account of the air quantities introduced from outside into the internal space. A decision between air supply operation and air recirculation operation is then made on the basis of a comparison of the air qualities inside and outside. The pollutant sensor is preferably located in a casing whose internal space is accessible to gases through an opening which is preferably sealed by a gas-permeable membrane.

摘要： A method for testing and adjusting catalytic exhaust gas emission control systems of internal combustion engines, in which the fuel-air-ratio is regulated by means of a .lambda.-probe (control-probe) arranged in the exhaust gas stream upstream of the catalyst, whereby the exhaust gas stream is measured downstream of the catalyst by means of a further .lambda.-probe (test-probe). The voltage average value and amplitude magnitude of the signal produced by the test-probe are determined and serve for adjusting the operating point of the control system and for the recognition of the catalyst efficiency.

摘要： A system is provided for measuring the amount of oxygen in exhaust gas emitted by an internal-combustion engine. The system includes an exhaust pipe for conducting engine exhaust gas and a probe for determining the oxygen content of engine exhaust gases. The exhaust pipe has a side wall formed to include an aperture for continuously discharging a portion of the engine exhaust gas flowing through the pipe. The system further includes a support housing for positioning the probe at a location outside of the exhaust pipe in proximity to the side wall aperture so that the probe is exposed to the engine exhaust gas portion discharged through the aperture and for collecting exhaust gas in a space surrounding the probe. The aperture is sized to permit exhaust gas collected in the support housing to be reintroduced into the exhaust pipe so that collected exhaust gas will be exchanged continuously with exhaust gas flowing through the exhaust pipe.
