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.
