摘要： This disclosure is directed to a method for operating a wind turbine which includes a speed-variable drive system. The system includes an electrical machine and a pulsewidth modulation-controlled converter. The speed-variable drive system is connected to an electrical grid. In the event of a transient grid fault, a frequency of the pulsewidth modulation is determined in response to a current in an electrical circuit connected to the converter.

摘要： A method determines a vehicle mass of a self-driving vehicle, wherein an internal force can be exerted on the self-driving vehicle by the automated control of an electronic drive system and/or an electronic braking system. The method includes determining whether a trigger event is present indicating a change in vehicle mass is likely, and activating a learning operating mode in the presence of a trigger event wherein the self-driving vehicle is operated alternately in a first and a second phase. In the first phase, an internal force is exerted on the self-driving vehicle, and in the second phase, an internal force is exerted on the self-driving vehicle. A disturbing force acting in the phases is determined. The vehicle mass is determined depending on the vehicle acceleration and the internal force present in each phase, as well as depending on the determined disturbing force.

摘要： A method for activating a fluid solenoid valve in a fluid system of a vehicle, in which, in order to set a switching mode, an activation voltage is applied to a coil arrangement of the fluid solenoid valve. The activation voltage is set depending on an operating criterion to at least two different operating modes, wherein, in a first operating mode, a current regulation of the coil current flowing through the coil arrangement is performed, and in a second operating mode, differing from the first operating mode, the activation voltage is set without the current regulation.

摘要： A two-stroke engine includes a cylinder having a combustion chamber. The combustion chamber is delimited by a piston guided in a reciprocating manner in the cylinder and drives a crankshaft. A first intake channel opens into the crankcase interior. A transfer channel opens into the crankcase interior via a transfer window on a cylinder bore of the cylinder and via a passage opening. A second intake channel is provided for supplying scavenging air to the transfer channel. The first intake channel and the second intake channel are configured for supplying air. An injection valve configured for injecting the entire quantity of fuel to be supplied to the engine directly into the crankcase interior is disposed on the crankcase. A method for operating a two-stroke engine provides that the entire quantity of fuel to be supplied to the engine via a metering installation is supplied directly to the crankcase interior.

摘要： An exhaust gas treatment arrangement for an exhaust gas system of an internal combustion engine includes a first exhaust gas flow path leading from an exhaust gas inlet provided on a housing to an exhaust gas outlet provided on the housing and a second exhaust gas flow path leading from the exhaust gas inlet to the exhaust gas outlet. The second exhaust gas flow path is separate from the first exhaust gas flow path. A flow path switching unit changes the exhaust gas stream parts, which are conducted in the first exhaust gas flow path and the second exhaust gas flow path. A reactant supply device supplies reactant into the second exhaust gas flow path downstream of the exhaust gas inlet and an SCR catalyst arrangement is provided in the second exhaust gas flow path upstream of the exhaust gas outlet.

摘要： A work apparatus includes a housing part and a stud bolt for fastening a work tool on the housing part. The stud bolt extends along an axial direction and has a first section and a second section in the axial direction. The first section is at least in part arranged in a receptacle of the housing part. The second section protrudes from the housing part in the axial direction. The first section of the stud bolt in a first lower portion thereof has an outer thread which, for transmitting longitudinal forces (L), threadably engages an inner thread of the receptacle to define a threaded connection. The first section for transmitting transverse forces (Q) to the housing part, in a second lower portion thereof, has a support region supported on the receptacle. The support region is disposed at a spacing (a1) from the threaded connection.
