Patent number: 7234430Abstract: A method for heating a glow plug for a diesel engine to its desired temperature by supplying power to the glow plug in a controlled fashion. During a certain time interval after termination of a previous glow process, a mathematical model is used to determine the values for the supply of power to the glow plug, which includes the values of the actual thermal state of the glow plug, the time elapsed since the end of the previous glow process and the parameters of the diesel engine relevant for a glow process.Type: GrantFiled: October 18, 2004Date of Patent: June 26, 2007Assignee: Beru AGInventors: Olaf Toedter, Heinz-Georg Schmitz, Andreas Bleil, Joerg Stoeckle, Hans Houben

Patent number: 7228730Abstract: A pressure-measuring glow plug for a diesel engine with a plug body (3, 4) for insertion into a cylinder of the diesel engine, a heating rod (1) which is arranged in the plug body (3, 4), and a pressure sensor, which is arranged under an initial tension between the heating rod (1) and the plug body (3, 4), in such a way that the pressure sensor (7) is acted upon by the pressure prevailing in the combustion chamber of the cylinder. The heating rod (1) transmits the pressure in the combustion chamber of the cylinder to the pressure sensor (7) and is arranged so as to be displaceable in a sliding manner in the axial direction relative to the plug body (3, 4). A seal in the form of a bellows-shaped component (2) is provided between the heating rod (1) and the plug body (3, 4).Type: GrantFiled: September 13, 2005Date of Patent: June 12, 2007Assignees: Beru AG, Texas Instruments Holland B.V.Inventors: Michael Haussner, Hans Houben, Frank Pechhold, Friedrich Mayr, Ulf Wyrwich

Patent number: 7193183Abstract: A glow plug connector for a glow plug with built-in sensor, especially built-in pressure sensor, comprising a casing made of an electrically insulating material, which can be placed onto the glow plug. Provided centrally in the casing is a high-current connection which is connected to the high-current contact of the heating devices of the glow plug when the connector is placed thereon. Sensor contacts are provided on the casing insulated with respect to the high-current connection for contacting the sensor connections of the built-in sensor when the connector is placed thereon. For sealing an O-ring is provided on the outside of the casing whereas a locking mechanism serves to deliver the withdrawal force which must be overcome so that a coupling placed thereon can be removed from the glow plug connector. The connector is part of a system with a glow plug connector and glow plug.Type: GrantFiled: January 21, 2005Date of Patent: March 20, 2007Assignees: Beru AG, Hirschmann Automotive GmbHInventors: Michael Haussner, Gerald List, Frank Pechhold, Hans Houben, Juergen Haefele, Werner Jaeger

Patent number: 5211009Abstract: A method for regeneration of a particulate filter in which the attainment of a stable idling operating condition of the diesel engine is waited for, at least within a specifiable time period after the starting of the diesel engine, rotation-speed signals of the diesel engine being registered in the specifiable time period, before a control device registers and evaluates further operating values and outputs control commands to devices of the particulate-filter system in order to insure reliable burning off of soot particles deposited in the particulate filter and prevent damage to the particulate filter due to incorrect control actions.Type: GrantFiled: December 10, 1991Date of Patent: May 18, 1993Assignee: Kloeckner-Humboldt-Deutz AGInventors: Hans Houben, Heinrich Berendes, Reinhard Pusch, Axel Rodemeister

Patent number: 4831917Abstract: A multiple piece piston is provided for a diesel internal combustion engine having a combustion chamber depression in the crown of the piston. In order to achieve a low rate of heat flow into the piston ring area and thus into the cylinder liner which surrounds the piston, a separate piston base or crown surrounding the combustion chamber depression is formed by a ring element made of a material having poor thermal conductivity, and the main body of the piston is made of a material with high thermal conductivity. The heat of combustion is thus conducted mainly axially through the piston main body and absorbed by sprayed cooling oil. The cooling oil, thus heated, can be utilized for heating purposes.Type: GrantFiled: July 22, 1987Date of Patent: May 23, 1989Assignee: Kloeckner-Humboldt Deutz AGInventors: Hans Houben, Eckhard Haas
