In a method for operating a fluid valve for controlling or regulating a fluid, having at least one movable valve component is displaceable with the aid of at least one electrical actuating signal which contains at least one first actuating signal portion which causes an oscillating valve motion of the valve component. Pressure oscillations generated in the fluid due to the oscillating valve motion are detected, and are used for regulation of the oscillating valve motion caused by the first actuating signal portion.

A device for utilizing waste heat of an internal combustion engine. A heat exchanger of a circuit of a working medium is provided in its exhaust system. A pump is connected upstream from the heat exchanger, the circuit containing an expansion machine. A coupling heat exchanger is located in the circuit of the working medium, the working medium of the circuit and the cooling medium of the internal combustion engine flowing through the coupling heat exchanger.

Device for utilizing waste heat

A device for utilizing the waste heat of an internal combustion includes a single-stage or multi-stage supercharging device, which is designed as an exhaust-gas turbocharger in particular. The single-stage or multi-stage supercharging device is assigned an additional supercharging device including an expansion machine acted upon by an auxiliary circuit, in particular a steam circuit.

Device for supporting a supercharging device

An internal combustion engine having an exhaust gas recirculation device for recirculating exhaust gas of the internal combustion engine to a fresh-air side of the internal combustion engine. For this purpose, it is provided that the exhaust gas recirculation device has at least one compressor for compressing the exhaust gas supplied to the fresh-air side of the internal combustion engine.

Internal combustion engine

For operating an internal combustion engine having a throttle situated in an exhaust line or exhaust return line, in which a heat engine is driven by a quantity of heat produced by the internal combustion engine, in a first non-heating operating mode of the internal combustion engine, a first setpoint value is preset, a first operating parameter that characterizes a temperature of the internal combustion engine is detected, a first triggering value is determined for the triggering of the at least one throttle as a function of the first setpoint value and the first operating parameter, the at least one throttle is triggered in accordance with the first triggering value, and the at least one heat engine is driven by the resulting quantity of heat.

The current invention relates to an apparatus for cooling and/or heating a motor vehicle, with at least one coolant pump for circulating a coolant in a cooling and heating system, with a main cooler segment, which has a main cooler inlet and a main cooler outlet, wherein the main cooler inlet is at least intermittently connected to at least one coolant outlet of an engine to be cooled, in particular an internal combustion engine, of the vehicle, and its main cooler outlet is connected to at least one coolant inlet of the engine, and with at least one other, secondary cooler segment provided in addition to the main cooler segment and at least one other unit to be cooled, which is connected to the cooling and heating system, and the apparatus have at least one bypass line with a bypass valve, which is associated with the at least one secondary cooler segment and is disposed parallel to this secondary cooler segment in the cooling and heating system of the motor vehicle.

Device for cooling and heating a motor vehicle

An electric machine, particularly a generator for motor vehicles, includes a housing and a casing enclosing the housing concentrically, the casing, together with the housing, bounding an annular space that is sealed in a fluid-tight manner and is connected to a coolant outflow and a coolant inflow. To achieve a uniform circumflow of the housing with sufficient cooling capacity, even given low volumetric flow of the coolant, a plurality of axial guide bars are arranged in the annular space, so that the coolant restrictedly flows in an axially wide-strip manner through the annular space within space segments arranged in a row in the circumferential direction, with an opposing flow direction in successive space segments.

A method for controlling/regulating a process in a motor vehicle, in particular a combustion process, gear-shifting process, or braking process, with the help of a characteristics grid map, which is defined by a plurality of performance quantities of the process and represented by data points that have corresponding characteristics-map values. At least one characteristics-map value is determined from the characteristics grid map in a control cycle for an operating point by first determining adjacent data points, which define an interpolation range in which the operating point lies, and by then interpolating between the adjacent data points. To reduce the computational time for interpolation, the at least one characteristics-map value is determined for the operating range within the framework of a linear interpolation based on a minimum number of data points. The minimum number of data points results from a number of the plurality of performance quantities of the process, which define the characteristics map, plus one.

A closure for a tank, in particular a fuel tank for a motor vehicle or the like, that has a tank filling pipe which can be closed with a closure flap, is described. The closure flap has a locking device with which it can be locked and unlocked and is also connected by a hinge or the like, so that it can move into the interior of the tank filling pipe. The locking device is located completely beneath the closure flap so that the closure flap can be locked and unlocked. Thus the locking device is not accessible from the outside, so it cannot be damaged or operated by an unauthorized party. The tank filling pipe can also be sealed airtight by the closure flap or by a closure valve arranged in the tank filling pipe.
