Abstract

A turbo-compound-IC engine has an intake pipe (9), an exhaust pipe (5), a turbo-compressor (3) whose first turbine stage is coupled to the exhaust so as to drive the compressor stage in the intake pipe and a second turbine stage downstream of the first stage, coupled by gearing 911) to the crankshaft. A compression brake device and valves (14) are located in the exhaust pipe upstream of the second turbine stage, used to reduce the gas flow to this second stage. The valves are in a pipe (19) on the suction side of the compressor in the intake pipe. There is a cooler on the intake side of the compressor for the exhaust gases coming through the valves.
