A film capacitor including a core, a plurality of film layers wrapped around the core, and at least one first spacer arranged between two first film layers of the plurality of film layers, wherein an interstice configured outside of a spacer cross-section is provided between the two first film layers by the at least one first spacer.

Film capacitor and motor vehicle

A pulse inverter for operating an electric machine of a motor vehicle from a motor vehicle battery, including a housing for delimiting an interior, a power electronics system, provided in the interior of the housing, for converting direct current to alternating current, a first cooling circuit configured to dissipate heat from an outer side of the housing facing away from the power electronics system, and a second cooling circuit, which is separated from the first cooling circuit and communicates with the interior of the housing, configured to directly liquid-cool the power electronics system with an electrically insulating fluid. (FIG.)

Cooled pulse inverter for operating an electric machine of a motor vehicle

A rotor () for an electric machine has a sheet stack () arranged between a first end plate () and a second end plate (). The first end plate and the second end plate () are connected to each other by pipes () that extend at least partially through the sheet stack (). Each pipe () has a cooling channel () for conducting a coolant. The pipes () and the first end plate () are constructed as an integral pipe/end plate ().

Rotor for an electric machine

The invention relates to a motor vehicle having a lighting device (-), which is combined with a noise-output device, and having an electrical drive device. In order to optimize a motor vehicle having a lighting device, which is combined with a noise output device, and having an electrical drive device in respect of the installation space required for the noise output device, at least one diffusing lens of the lighting device () is designed as a sound-emitting device.

Motor vehicle

A motor vehicle has an internal combustion engine () and a drive train () with an electric machine that can be operated as a generator. A supercharger () supplies air through a mass flow line () to an inlet side of the internal combustion engine (). The air mass flow line () has no throttle valve. The supercharger () also selectively can function as a secondary air pump to blow secondary air through a branch () of the mass flow line () and to an outlet side () of the internal combustion engine () upstream of a catalytic converter. A control unit causes the electric machine to operate as a generator when the supercharger () is functioning as a secondary air pump to compensate for excess torque caused by a charge pressure generated by the secondary air.

Drive train for a motor vehicle

The invention relates to a method and an arrangement for controlling a drive unit (), especially of a vehicle, having a combustion engine (). The method and arrangement make possible a correct charge control when utilizing a secondary air charger () as well as make possible a diagnosis of the secondary air charger (). Secondary air is blown into an exhaust-gas system () of the combustion engine () via the secondary air charger (). The secondary air charger () is driven by a pressure drop across an actuating element () for adjusting an air supply to the engine (). The actuating element () is driven for adjusting an air supply to the engine () corrected in dependence upon an air mass flow driving a turbine () of the secondary air charger ().

Method and arrangement for controlling a drive unit having an internal combustion engine

In a pressure sleeve in particular a vibration pickup, an abutment surface is formed as a circumferential ring at a location radially spaced from a central point. Therefore, the pressure sleeve can be fully pressed against the structure to be monitored by a mounting screw. Therefore a sensor provided with the pressure sleeve can approximately linearily extending and disturbance measuring signals.

Pressure sleeve

A knock sensor for indirect or direct fixing to an internal combustion engine has a housing (10) with a pressure sleeve (11) on the outer side of which a piezoceramic disk, a seismic mass (16), the contact disks (14), and the insulating disks (13) are arranged. The insulating disks (13) or the piezoelectrical disk (15) are or is made slightly electrically conductive so that the voltage spikes which occur due to the pyroelectrical effect can be easily eliminated. In this way, faulty measuring and interference can be avoided in the electrical circuit connected to the knock sensor.
