Abstract: The invention concerns a drive arrangement (1) for the combustion of fuel, with an internal combustion engine (2), an intake air compressor (4) and an exhaust gas turbine (5) which drives the latter. An intake-air distributor (7) is provided between the compressor (4) and the internal combustion engine (2) and an exhaust gas chamber (8) is disposed between the internal combustion engine (2) and the exhaust gas turbine (5). Further provided are a container (12) and a nozzle (18) which is connected thereto via a first water-conveying pressure line (13), the nozzle injecting water into the scavenging air in front of the compressor (4). The internal combustion engine takes the form of a diesel engine (2), and the first pressure line (13) and the nozzle (18) are connected to the intake line (9) in front of a compressor (4) such that the atomizing water is injected into the compressor (4).

Abstract: In a means for detecting the wear of a current interrupting contact (4) there is used a light conductor (12) as a connecting link between the contact (4) and a detector (20) arranged at ground potential. The light conductor is inserted into an aperture (11) provided from the rear side of the contact, the bottom of said aperture being positioned at the level corresponding to a worn out contact. When the wear has grown so great that the light conductor (12) is exposed, the light or heat of the breaking arc will generate or interrupt a light signal, which via the light conductor is transmitted to the detector.

Abstract: When reversing a marine power plant, due consideration must be given to the fact that the inertia of the ship will continue to force the ship through the water during a moment of time after the shut down of the prime mover, with the propeller then acting as a water turbine tending to rotate the propeller shaft in the same direction as before. If the propulsion plant includes a gas turbine and a reversing gear, the reversing gear is designed in such a manner that the part thereof connected to the turbine will represent, in use, a smaller inertia than the part connected to the propeller shaft, with the propeller shaft together with the propeller attached thereto representing a considerable rotating body.
