Abstract: The invention relates to a combustion engine 7 of compound type in which the exhaust gases partly drive a first turbine 3 for driving a compressor 4 for supplying and compressing combustion air, partly a second turbine 2 which, via a mechanical transmission 1 transmits the residual energy in the exhaust gases to the crankshaft 10 of the combustion engine. The exhaust gas brake 6 being placed downstream, in the exhaust gas flow direction, after the second power turbine 2 results in a greatly increased braking effect at a given limited permitted exhaust gas temperature. In corresponding conditions with regard to exhaust gas temperature and type of exhaust gas brake damper the braking effect extracted for compound engines can be improved by up to 27% compared with a conventional supercharged diesel engine.

Abstract: Device for feeding oil from the lubricating oil system of an internal combustion engine to units mountable on a unit support plate which is secured to the engine block. On one surface of the unit support plate facing out from the engine block there are one or more oil distribution ducts incorporated in the support plate, each of which connects to the lubricating oil system of the engine at the block to at least one associated mounted unit. Each duct is defined by a groove in the support plate surface outward from the engine block. Each groove is covered on the surface of the support plate by a cover plate secured in the unit support plate. Each duct groove has its associated cover plate preferably secured in the unit support plate by shape and/or friction.

Abstract: Arrangement for effective oil supply to a working chamber in a hydrodynamic coupling flushed through with oil, and lubrication of the bearings of the coupling. The working chamber is supplied with oil through a channel in the stationary part of the coupling via a main bearing forming part of the coupling and bearing the turbine in the pump wheel. A second main bearing bearing the pump wheel in the stationary part receives a continuously limited throughflow of lubricating oil via a throttle in communication with the flow of oil to the first main bearing. By means of the invention, a steady flow of oil to the working chamber of the coupling is obtained, and at the same time all the main bearings receive a continuous throughflow of lubricating oil which does not cause any great oil friction losses in the bearings during stationary running.
