Abstract
An arrangement for a supercharged combustion engine includes a first compressor compressing air in the engine air inlet line as a first stage and a second compressor compressing the air in the inlet line as a second stage, a first coolant-cooled charge air cooler cooling the air after it has been compressed in the first stage and before it is compressed in the second stage, and an air-cooled charge air cooler cooling the compressed air when it has been compressed by the first stage, a second coolant-cooled charge air cooler cooling the compressed air after it has been compressed in the second stage and before it is compressed in the air-cooled charge air cooler. Exhaust gases in an exhaust line from the engine drive turbines which operate the compressors. A return line from the exhaust line and connected into the inlet line has a cooler for the exhaust gases before mixing the gases with the inlet air.
