20080300732 | Bus Communication Management in a Motor Vehicle with a Plurality of Control Devices Linked by a Bus and Method of Controlling the Bus Communication Management - An apparatus for a motor vehicle includes a first control device, a plurality of second control devices, and a bus system that links the control devices. Wherewith an activity of the control devices is dependent on communication between the control devices which is transmitted via the bus system. The apparatus is distinguished in that the first control device is configured such as to deny communication to (or via) the bus system under prescribed conditions, and the second control devices are configured to cancel (interrupt) a communication to (or via) the bus system if the first control device denies the communication. Additionally, a method is disclosed wherein the apparatus is operated in the described manner. | 12-04-2008 |

20100037765 | METHOD FOR THE PRODUCTION OF A PISTON OF AN INTERNAL COMBUSTION ENGINE IN ORDER TO FORM A REINFORCEMENT OF A COMBUSTION CHAMBER CAVITY OF THE PISTON - A method for producing a piston of an internal combustion engine in which a first blank and at least one additional black are provided with a somewhat cylindrical shape. The blanks are joined together, and the obtained piston blank is subjected to a shaping process in which a combustion chamber cavity of the piston is formed in the area of a joining point between the first and the second blank. The material of the second blank forms a reinforcement for at least the combustion chamber cavity. | 02-18-2010 |
20100275873 | SIMPLE FRICTIONAL WELD - A cooling channel piston for an internal combustion engine which includes a piston bottom and a piston shaft that are joined thereto of a friction welding process. The piston bottom and the piston shaft jointly form a cooling channel. An annular wall which radially delimits the cooling channel towards the outside is formed by the piston bottom and/or the piston shaft. The annular wall can be sealed by a welding process once the piston bottom and the piston shaft have been joined together. | 11-04-2010 |
20110119914 | Piston For Internal Combustion Engines, Produced By Means of a Multi-Orbital Friction Welding Method - A method for producing a piston of an internal combustion engine, designed as a one-piece cooling channel piston. The piston includes an upper part and a lower part supported by corresponding circumferential joining bosses together forming a joining zone. In order to produce a bonded joint of the upper part and the lower part, the joining bosses are connected by means of multiorbital friction welding in the region of a rotationally symmetrical or rotationally asymmetrical joining zone. | 05-26-2011 |
