Abstract: A system for cooling a dynamoelectric machine is provided. The system includes a coolant medium inlet, a coolant medium outlet and a fan connected to a rotor of the dynamoelectric machine, The system further includes a flow control device configured to control the amount of the coolant medium passing through the dynamoelectric machine by controlling an opening area of at least one of the coolant medium inlet and the coolant medium outlet. The system further includes a winding temperature measurement system configured to measure the temperature of one or more windings in the dynamoelectric machine, and control the flow control device by adjusting the opening area of at least one of the coolant medium inlet and the coolant medium outlet based on the temperature of the windings in the dynamoelectric machine to at least one of reduce windage loss and control coolant medium pressure within the dynamoelectric machine.

Abstract: Method of operating a combustion engine provided with at least one flushed prechamber, wherein the at least one prechamber is connected to a main combustion chamber of the combustion engine and wherein—during a compression phase immediately preceding the ignition in the main combustion chamber—after ignition has taken place in the prechamber, in a first transfer phase gas transfers from the prechamber into the main combustion chamber, wherein after the first transfer phase, an at least two-phase, incompressible medium—preferably water—is introduced into the prechamber.

Abstract: The invention relates to a power plant unit (1) for generating electrical power, comprising at least a first electric generator (2) which can be driven by a gas turbine (3), at least a second electric generator (4) which can be driven by a reciprocating piston engine (5). According to the invention, the at least one first and the at least second electric generator (2, 4) feed electrical power into a common network (6), wherein a section switch (7) is provided by which the common network (6) can be electrically connected to an electrical consumer (8).

Abstract: The invention relates to a power station comprising at least two generators (3, 3?) for generating electricity, wherein a gas turbine (1) is provided for driving one of the at least two generators (3, 3?), and a reciprocating piston engine (2) is provided for driving the other of the at least two generators (3, 3?). According to the invention, the reciprocating piston engine (2) comprises at least one charge air inlet (21) for precompressed charge air, and the gas turbine (1) comprises at least one compression stage (11), the at least one charge air inlet (21) of the reciprocating piston engine (2) being connected to an exit of the at least one compression stage (11) via a charge air line (41).

Abstract: Prechamber system for an internal combustion engine, having:—a prechamber,—a fuel introduction device,—a dead space which connects the fuel introduction device to the prechamber, wherein a channel is provided which connects the prechamber to the dead space.
