Abstract: An electric generator system may include a housing assembly that forms an inlet vent opening and an outlet vent opening, an electric generator, an engine, and at least one fan positioned within the housing assembly, an electrical component, and an electrical component fan that is positioned proximate to the inlet vent opening and configured to draw air from externally of the housing assembly through the inlet vent opening and direct air to the electrical component during operation of the electric generator system. The at least one fan may be positioned generally opposite of the electrical component fan relative to the electrical component to draw air across the electrical component during operation of the electric generator system.

Abstract: A method of operating an internal combustion engine with at least one piston-cylinder unit, and preferably a plurality of the piston-cylinder units, whereby, in a detection mode of the internal combustion engine one or more knock-promoting measures are taken until knocking has occurred in at least one piston-cylinder unit, and the measure(s) is/are intensified until a termination criterion is reached, whereby it is detected in which of the piston-cylinder units knocking has occurred, and whereby, in piston-cylinder units detected as knocking, the ignition time for a normal operating mode of the internal combustion engine is retarded.

Abstract: A cross member for arrangement on a bumper system for a motor vehicle includes a single-piece open profile part made of uniform material and having a U-shaped cross section to define a first opening. The profile part has a curvature directed in a travel direction of the motor vehicle and includes a center zone having a second opening which is configured to point backwards in the travel direction, and end zones which have each an attachment area for a crash box and in which the first opening is configured to point forwards in the travel direction.

Abstract: A bumper for a motor vehicle includes a crossbeam having a hat profile defined by a bottom wall, legs respectively adjoining the bottom wall, and flanges respectively extending from the legs. The hat profile has sections of varying cross sectional configuration in a longitudinal direction. A face plate closes the hat profile to define a hollow space, with the crossbeam being mountable with the face plate such as to point outwards. An upper one of the legs has a width which is greater than a width of a lower one of the legs in a center section of the crossbeam. The crossbeam has curved ends oriented in a direction of the motor vehicle, and the face plate includes in the center section a stiffening embossment which is oriented into the hollow space defined by the hat profile and the face plate.

Abstract: A bumper for an automobile includes a crossbeam which is formed from at least two separate hollow profiles, wherein the hollow profiles abut one another along a longitudinal wall and are joined with one another. The abutting longitudinal walls form a double web oriented in the longitudinal direction of the automobile. The hollow profiles may have an identical cross-sectional configuration. The hollow profiles may be roll-formed or extruded. The modular construction of the crossbeam from separate hollow profiles allows a lightweight construction and allows the load characteristic of the crossbeam to be functionally adapted to different requirements depending on the vehicle or vehicle class.

Abstract: A bumper crossbeam for a motor vehicle includes an outer section configured as a roll-formed hollow profile which is closed at least in some areas. At least one inner section, configured as a separate component, is arranged in the outer section and connected to the outer section. The inner section has at least one wall extending from a front section zone of the outer section to a rear section zone of the outer section.
