Abstract: In a method for heating up the intake air of an internal combustion engine during the preglow phase or start-up phase, the heating power is controlled by a control unit of the engine electronics as a function of the operating data of the internal combustion engine. During the preglow phase, the heating element is initially supplied with full current until the heating element reaches its reference temperature. After the reference temperature has been reached and until the start-up phase, a post-heating phase begins in which the heating element is kept at a constant temperature by way of a relatively low power. During the start-up phase, in a first time period, the heating element is switched off, and in a second time period in which the speed of the internal combustion engine is raised to the starting speed, the heating element is switched on again.

Abstract: In an internal combustion engine with an air separation unit and a method of realizing such an internal combustion engine, the air separation unit is able to be fed by intake air compressed by a charging unit and cooled by a charged air cooler. The internal combustion engine can at least periodically be fed with a retentate, provided by the air separation unit, having such a composition that, in comparison to normal, it is oxygen enriched. The air separation unit is connected to the outlet of the charged air cooler, and compressed intake air from the charging unit undergoes purification that includes the separation of fluid and/or solid contents before being fed into the air separation unit.

Abstract: In a motor vehicle and or a subassembly of a motor vehicle, e.g., a convertible or a roadster, with an opening roof, e.g., a soft top or a hardtop, which includes roof parts or roof elements which are mounted on a main bearing device so as to be able to pivot from a closed position into an open position, the main bearing device is fastened to a supporting structure of the motor vehicle, and with a roll bar which is fitted to the motor vehicle so as to be able to pivot from a storage position into a protective position. To reduce manufacturing costs, the main bearing device has an additional, secondary bearing device on which the roll bar is pivotally mounted.

Abstract: A passage structure for PEM fuel cells is configured locally differently in order to adapt the flow of gas on the membrane electrode assembly (MEA). Starting from the cathode entry port, the active gas volumetric flow per unit area on the MEA is locally varied by changing the number and/or cross section of the gas-carrying passages, so that the flow decreases toward the cathode exit port. Suitable configuration of the passage structure according to the invention allows the steam partial pressure to be optimally matched to the local conditions. The mass conversion is improved in these regions as a result without the electrolyte's drying out. At locations in the flowfield with a low gas humidity, the measures according to the invention (increased number of passages or passage width) significantly reduce the flow velocity. As a result, the transfer of water from the MEA to the gas flow is reduced and drying of the MEA is diminished.

Abstract: The invention relates to a shift lever arrangement for a transmission of a motor vehicle having a shift lever for setting a selected shift stage of the transmission, with the shift lever being mounted, by means of a positioning unit, so as to be movable between a non-use position of the shift lever and a use position thereof for setting the shift stages and/or vice versa, wherein an anti-trap unit is assigned to the shift lever, in such a way that, after the activation of the positioning unit for adjusting the shift lever between the non-use position and the use position thereof and/or vice versa, the positioning force generated by the positioning unit and acting on the shift lever can be at least reduced.

Abstract: A child seat which can be fastened to a vehicle seat of a vehicle by means of a fastening system comprises a child belt system for securing a child sitting on the child seat apparatus for coupling a vehicle seat belt system, which has a belt strap and a belt strap tensioning device, to the belt system of the child seat. The coupling apparatus is designed such that, when the belt strap tensioning device is activated, the child seat belt system is also tensioned. The coupling apparatus has a holder into which the belt strap provided on the vehicle can be hooked. holder is designed and arranged in such a manner that it serves to receive the lap belt section of the vehicle's belt strap.

Abstract: The invention relates to a vehicle occupant protection and/or comfort system (1) for a vehicle (10), comprising a plurality of adaptive protection system and comfort components (8.1, 8.2) which are each assigned to a sitting place (SP1 to SPn) and can be adjusted by means of a safety and/or comfort profile (PS, PK) which is related to a vehicle occupant who is occupying the respective sitting place (SP1 to SPn) and can be activated by means of an authentication system (2). The authentication system (2) here comprises a plurality of person identification devices (4.1 to 4.

Abstract: The aim of the invention is to be able to produce directly cast GGV and GGG melts in a single-stage process, simultaneously determine the physical and mechanical parameters such as the strength index and the pipe index by means of a thermal analysis and a mathematical evaluation model, continuously compare the process data to the target data with the aid of the process control computer, optimally determine the amounts to be added, and introduce the determined amount into the melt.

Abstract: In a method and apparatus for measuring and displaying the engine oil filling level in a vehicle having a filling level switch or sensor, measured values of the switch or sensor, in the form of determined time components, are summed to determine a state duration of a particular state of the engine oil filling level. The state duration is compared with predefined time limiting values of the respective state of the engine oil filling level. According to the invention, the length of the individual time components is determined as a function of driving-state-dependent parameters.

Abstract: A method for energy management of air-conditioning units in motor vehicles in which each of the air-conditioning units has a plurality of air-conditioning compressors prevents very heavy loading of an engine of a motor vehicle and prevents the engine from almost stalling when the air-conditioning compressors start up, as currently occurs during starting of the engine of the motor vehicle, after idling of the engine of the motor vehicle, and after an acceleration process in which the engine was in the full load mode. Each of the air-conditioning compressors is allocated a different priority, with the highest priority, for example, assigned to the air-conditioning compressor for a front vehicle region which is intended, inter alia, to prevent the front windscreen from misting up by removing moisture from the air. A lower priority can be assigned to the air-conditioning compressor for a rear vehicle region.

The invention further concerns an oil channel core.

Abstract: A refrigerant compressor has a control valve for controlling the degree of conveyance of the refrigerant compressor by setting a drive housing pressure pC of the refrigerant compressor. A control body controls a conveying-side control line between a discharge chamber, acted upon by high pressure of the compressor, and the drive housing of the compressor, and also controls a suction-side control line between the drive housing and a suction chamber, acted upon by suction pressure of the compressor variably in a throttling and/or shutting-off manner. The control body is driven electromagnetically. To improve the refrigerating capacity and the control behavior of the refrigerating system, the control body, which can shut off both the conveying-side and the suction-side control line, is also driven by means of a pressure cell.
