摘要:
A pulse supercharger for internal combustion engines, in which the pulse supercharger is situated in a charge air duct. The flow cross-section of the charge air duct for a charge air flow is opened or closed via the pulse supercharger. The pulse supercharger includes two synchronously operatable rotary slide elements.

An impulse turbocharger for an internal combustion engine. The impulse turbocharger is adapted to be used for controlling the air flow of an air supply conduit on the intake side of an internal combustion engine. The impulse turbocharger has a rotary valve which is connected by an elastic coupling to a rotary actuator.

摘要:
A method for operating an internal combustion engine in which combustion air is supplied to a combustion chamber of the internal combustion engine, which air is compressed with the aid of a pulse supercharger, the pulse supercharger being controlled in such a way that optionally, in a first operating mode, the combustion air is compressed in order to support a compressor of a turbocharger, or in a second operating mode, the combustion air compressed with the aid of the compressor is cooled.
摘要:
In an automotive drive, at least one dynamic characteristic of a bearing by which the automotive drive is supported on a beam is selectively influenced during operation of the automotive drive (active bearing). It is provided that a change in an instantaneous operating variable of the automotive drive is determined from a change in a state variable of the active bearing that influences its dynamic characteristic.

摘要:
The disclosure relates to a method for operating a positioning actuator system with an electronically commutated actuator drive for driving an actuator element, having the following steps: non-volatile storage of a position information item of the actuator element or of a rotor of the actuator drive which was detected last as a reference position before the positioning actuator system is switched off; in the case of switching on of the positioning actuator system retrieval of the reference position and actuation of the actuator drive by energizing the actuator drive in accordance with a space phasor which is dependent on the reference position. The object is to make available an improved method for releasing blockage of an actuator element or actuation after activation of a motor system with a maximum actuating torque. For positioning actuators with commutated motors such as, for example, synchronous motors.

A method for calibrating a positioner system that has an electronically commutated servomotor and a counterforce-loaded actuator coupled thereto includes actuating the servomotor such that a first motor magnetic field of a first strength is generated and determining a first position specification for the position of the actuator aligned to the first motor magnetic field. The servomotor is actuated such that a second motor magnetic field of a second strength is generated and a second position specification for the position of the actuator aligned to the second motor magnetic field is determined. Based on the first and the second position specifications, a position specification which indicates a position of the actuator under the assumption that the actuator is not loaded with a counterforce is determined. The determined position is allocated to a rotor position which corresponds to the direction of the first and second motor magnetic field.
摘要:
A method for operating an internal combustion engine having at least one triggerable intake valve and at least one triggerable discharge valve, in which the internal combustion engine is directly started in a start-up operating mode and, following the start, is operated in at least one other operating mode. A starting discharge instant of a discharge valve of the internal combustion engine that is used during the start-up operating mode is retarded in time with respect to a standard discharge instant so as to improve the direct start-up characteristics of the internal combustion engine. In addition, to further improve the direct start-up characteristics, it is possible to retard a closing instant of an intake valve that is used during the start-up operating mode with respect to a standard closing instant.
