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.

Combustion engine of turbocompound type with exhaust gas brake

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.
