Patent number: 5259813Abstract: 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.Type: GrantFiled: February 26, 1992Date of Patent: November 9, 1993Assignee: Mercedes-Benz AGInventors: Jorg Abthoff, Hans-Dieter Schuster, Friedhelm Nunnemann, Gunter Loose, Michael Osswald, Michael-Rainer Busch, Markus Fortkord

Patent number: 5256103Abstract: A ventilation arrangement for the interior of a motor vehicle, having at least a heating or air-conditioning unit. The ventilation arrangement has a fan for air exchange in the interior and a filter for the adsorption of odorous and/or harmful substances contained in the air stream. The filter is designed so that, for the widest possible spectrum of odorous and/or harmful substances, a filter effect is produced which is based on rapid adsorption of the odorous and harmful substances and a gradual desorption thereof with a long time delay. A high short-term concentration of the odorous and/or harmful substances is thus converted by the filter into an extremely low but, instead, long-lasting emission which, with sufficiently extensive dilution, remains below a preset odor threshold or nuisance threshold.Type: GrantFiled: February 21, 1992Date of Patent: October 26, 1993Assignee: Mercedes-Benz AGInventors: Jorg Abthoff, Hans-Dieter Schuster, Friedhelm Nunnemann, Peter Bach, Michael Osswald

Patent number: 5042248Abstract: An apparatus for the regeneration of a soot-particle filter is located in the exhaust-gas line of an air-compression, fuel-injected internal-combustion engine. The apparatus regenerates the filter using a process which burns off the soot particles in the filter. A device in the intake line is actuable as a function of the engine load and engine speed and controls the cross-section of the intake line. To prevent damage to the soot-particle filter body during a transition of the internal-combustion engine into the deceleration mode, immediately after the transition into the deceleration mode of the internal-combustion engine, the process and apparatus move the device for controlling the intake-line cross-section first out of its open position into a position to reduce the line cross-section to a minimum and thereafter continuously into its open position.Type: GrantFiled: April 12, 1990Date of Patent: August 27, 1991Assignee: Daimler Benz AGInventors: Jorg Abthoff, Hans-Dieter Schuster, Hans-Joachim Langer, Erwin Strohmer, Rolf Gabler, Roland Schulte

Patent number: 4877339Abstract: The invention relates to bearing support of a throttle valve shaft in the housing of an exhaust gas line in which the shaft is rotatably supported on both sides in a bearing sleeve element constructed cup-shaped. The cups themselves are retained by spring force against the housing extending correspondingly conically within these areas. In order to keep small the actuating forces necessary for the rotation of the throttle valve shaft, each bearing sleeve element is retained by itself against the housing by means of a spring supported at the housing and the securing of the shaft against any axial displacement takes place by a separate axial bearing.Type: GrantFiled: January 31, 1989Date of Patent: October 31, 1989Assignee: Daimler-Benz AGInventors: Hans-Dieter Schuster, Christoph Noller, Gottfried Wollenraupt, Reiner Kreeb, Roland Huss

Patent number: 4733358Abstract: A self-optimizing control method for optimizing the fuel/air ratio under non-steady conditions in an internal combustion engine is described; in this method, a probe is provided both before and after the catalyst. Control quantities and the time during which the post catalyst probe shows an undesirable fuel/air ratio are stored for certain specified engine-operating conditions in the non-steady range. When the same engine operating condition is repeated, reference is made to the stored control quantities and time and the control quantity is varied in the direction of the correct fuel/air ratio. The time now obtained is compared with the stored time and, if the time has decreased, the new control quantity and the new time are stored. The control values are iteratively corrected by repeating these procedures, when the same engine operating condition reappears, until the time reaches a minimum.Type: GrantFiled: July 3, 1985Date of Patent: March 22, 1988Assignee: Daimler-Benz AktiengesellschaftInventors: Jorg Abthoff, Dieter Schuster, Christoph Noller, Ferry Durschmidt, Gunter Loose

Patent number: 4704863Abstract: 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.Type: GrantFiled: December 19, 1985Date of Patent: November 10, 1987Assignee: Daimler-Benz AktiengesellschaftInventors: Joerg Abthoff, Hans-Dieter Schuster, Gunter Loose, Bernhard Jokl

Patent number: 4667469Abstract: 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.Type: GrantFiled: December 6, 1985Date of Patent: May 26, 1987Assignee: Daimler-Benz AktiengesellschaftInventors: Joerg Abthoff, Hans-Dieter Schuster, Gunter Loose, Bernhard Jokl
